00:00:00.001 --> 00:00:00.260
savrdce@auburn.edu: Little one go.

2
00:00:03.050 --> 00:00:11.240
RISE GSA Audrey Heun: yeah she she see if she gets like tired of me, being in here and then she'll come in and be like she wants to really be on the video screen.

3
00:00:13.310 --> 00:00:14.300
RISE GSA Audrey Heun: She really wants to.

4
00:00:14.960 --> 00:00:18.920
savrdce@auburn.edu: Be front and Center she just wants to learn something about quotations Paleo.

5
00:00:21.020 --> 00:00:24.410
RISE GSA Audrey Heun: There was um for the Northeast section, there was um.

6
00:00:25.670 --> 00:00:28.730
RISE GSA Audrey Heun: I think it's in Connecticut dinosaur national.

7
00:00:29.960 --> 00:00:33.140
RISE GSA Audrey Heun: Not there's like a national dinosaur museum.

8
00:00:34.580 --> 00:00:43.670
RISE GSA Audrey Heun: And they did this really cool field trip, and it was on a set it was on the weekend, so I made my kids sit with me we watched it and it was really fun so yeah.

9
00:00:44.720 --> 00:00:47.060
John Fronimos: Does that dinosaurs state park with the footprints.

10
00:00:47.180 --> 00:00:48.650
RISE GSA Audrey Heun: that's what it was yes.

11
00:00:49.970 --> 00:00:52.700
John Fronimos: And that's in Connecticut right and take classes up there yeah.

12
00:00:52.910 --> 00:00:55.820
RISE GSA Audrey Heun: yeah yeah they've been closed and so.

13
00:00:57.320 --> 00:01:13.550
RISE GSA Audrey Heun: A lot of things were a little different and they're kind of redoing a lot of different things, because they can right now with people not being there but they did a great job and they'd live stream did and have videos and they were like down crawling around and so it's really cool.

14
00:01:15.740 --> 00:01:25.820
Michael Thonis: yeah there's there's one of those in Connecticut and one of those Massachusetts both of them are in the well the hartford and the deerfield basins, those are the.

15
00:01:27.080 --> 00:01:29.360
Michael Thonis: Those are the the rift basins.

16
00:01:30.410 --> 00:01:31.340
Michael Thonis: mesozoic.

17
00:01:32.180 --> 00:01:33.920
savrdce@auburn.edu: Are they triassic or Jurassic.

18
00:01:34.730 --> 00:01:40.040
Michael Thonis: triassic I think 204 well I think yeah.

19
00:01:41.090 --> 00:01:45.110
John Fronimos: Thanks some of the track ways, or just up into the Jurassic.

20
00:01:45.350 --> 00:01:46.280
Michael Thonis: yeah I might be.

21
00:01:46.370 --> 00:01:51.890
Michael Thonis: that's why I hesitated but what's interesting is that there have been up there and he's been virtually no.

22
00:01:52.370 --> 00:02:03.710
Michael Thonis: almost no fossil bones found dinosaur bones found it's almost the entire there have been fossil fish found, but there are virtually it's almost entirely footprints.

23
00:02:04.310 --> 00:02:10.160
Michael Thonis: And there and they're in Massachusetts Massachusetts they're everywhere, you can go to the park, but you don't really need to.

24
00:02:11.330 --> 00:02:16.010
Michael Thonis: Because you can just walk out in the woods wherever you find it out crap there's footprints all over it.

25
00:02:17.060 --> 00:02:21.500
Michael Thonis: it's really astonishing and yet very few skeletal remains.

26
00:02:22.730 --> 00:02:26.060
Michael Thonis: And there's all kinds of theories about why you know why, why not.

27
00:02:28.040 --> 00:02:32.270
Michael Thonis: The museum is i'm with them i'm a trustee with museum of science in Boston and we.

28
00:02:33.470 --> 00:02:43.760
Michael Thonis: We, along with the state as a contest to two different species of dinosaur fossils that have been farewell footprints then a couple of pounds.

29
00:02:44.720 --> 00:02:56.960
Michael Thonis: Fossil bones, and we just just a month ago there was a contest and it was one of the most popular museum events ever it was to get people to name to choose which of the two.

30
00:02:59.240 --> 00:03:01.940
Michael Thonis: Which are the two dinosaurs would be the state dinosaur.

31
00:03:06.350 --> 00:03:09.110
Michael Thonis: And they were both cool they're both cool dinosaurs are small, but.

32
00:03:09.170 --> 00:03:09.650
Michael Thonis: You know.

33
00:03:09.860 --> 00:03:10.280
Very.

34
00:03:11.900 --> 00:03:16.700
savrdce@auburn.edu: Well, we have only 12 hey Scott there you're you're on the moon.

35
00:03:19.310 --> 00:03:20.000
savrdce@auburn.edu: up here.

36
00:03:21.140 --> 00:03:22.010
savrdce@auburn.edu: you're muted.

37
00:03:25.190 --> 00:03:26.630
Michael Thonis: Well, you can't hear anything on the moon.

38
00:03:26.720 --> 00:03:26.990
Saying.

39
00:03:29.600 --> 00:03:35.930
Scott Brande: hey look i'm a bit older than you so I figured 230,000 miles is efficient social distance in order.

40
00:03:39.800 --> 00:03:47.330
savrdce@auburn.edu: All right, well, it looks like we only have 12 out of the 53 attendees and I know at least a few of them told me they had.

41
00:03:48.500 --> 00:04:04.370
savrdce@auburn.edu: convene other sessions and that sort of thing, so I guess, we can get started, what I wanted what I wanted to do, though, before we actually to the Q amp a for the field trip is to acknowledge our sponsors.

42
00:04:08.150 --> 00:04:19.100
savrdce@auburn.edu: know a number of us were several hats for this meeting, and as as the sponsorship chair, I wanted to personally thank.

43
00:04:20.000 --> 00:04:39.680
savrdce@auburn.edu: The various sponsors for the meeting, and there are a number of corporate sponsors focused material southern company since Tara and Bob fossa comes with Fo sick mineral resources, incorporated and then of course we had excuse me, local support from our own department.

44
00:04:40.850 --> 00:04:46.610
savrdce@auburn.edu: Not only all the work that all the Faculty and students are doing, but some financial support for the meeting.

45
00:04:48.020 --> 00:04:56.750
savrdce@auburn.edu: Also, our college of science and mathematics here at auburn thank Dean Giordano, for his support and then we have a number of other.

46
00:04:57.920 --> 00:05:09.050
savrdce@auburn.edu: alumni and friends that are part of our auburn university geosciences advisory board that should be acknowledged for their their support as well, I also want to thank everybody.

47
00:05:10.070 --> 00:05:10.430
savrdce@auburn.edu: Who.

48
00:05:12.260 --> 00:05:20.390
savrdce@auburn.edu: put together sessions and led sessions, but also everybody who's participated in the in the meetings for those who attended.

49
00:05:21.740 --> 00:05:27.680
savrdce@auburn.edu: The meeting in the folks at GSA because I think they've they're handling this covert crisis.

50
00:05:28.880 --> 00:05:38.210
savrdce@auburn.edu: In a an incredible way and appreciate every everything they've done to help us get this rolling anyway i'll stop sharing the screen for now.

51
00:05:39.620 --> 00:05:53.540
savrdce@auburn.edu: And we can go ahead and and get started with our Q amp a hopefully everybody listening in received my email, I think I sent it on Wednesday evening, just to remind everybody that that.

52
00:05:54.410 --> 00:06:02.240
savrdce@auburn.edu: To get the most out of this session I guess it you really needed to kind of watch or attend the field trip beforehand.

53
00:06:03.350 --> 00:06:14.990
savrdce@auburn.edu: I apologize, that it was all pre recorded and and just kind of like a long very own PowerPoint presentation, it would have been nice obviously to visit the section which currently.

54
00:06:15.740 --> 00:06:23.180
savrdce@auburn.edu: Have katie boundary sands are about 40 feet underwater right now due to high discharge on the Tongue big be river.

55
00:06:24.440 --> 00:06:30.860
savrdce@auburn.edu: Of course coven would have kept us from getting out there and also some issues with access.

56
00:06:32.240 --> 00:06:41.510
savrdce@auburn.edu: To the exposure, but hopefully you got something out of it, hopefully, there were enough photographs and that sort of thing.

57
00:06:42.530 --> 00:06:46.520
savrdce@auburn.edu: That you found the trip informative anyway.

58
00:06:48.260 --> 00:06:50.060
savrdce@auburn.edu: But with that i'll just kind of.

59
00:06:51.500 --> 00:06:53.300
savrdce@auburn.edu: turn it over to kind of open it up.

60
00:06:53.960 --> 00:06:57.470
Michael Thonis: I know, on that point, the one you just made about the location.

61
00:06:57.980 --> 00:07:07.550
Michael Thonis: If I think you do mentioned in the video that there's a maybe something under a bridge somewhere, but is that it in terms of in terms of the boundary in that area.

62
00:07:09.200 --> 00:07:10.310
Rindsberg, Andrew: I can speak to that.

63
00:07:10.610 --> 00:07:12.950
savrdce@auburn.edu: yeah go ahead Andy Andy just communicated so.

64
00:07:14.480 --> 00:07:16.760
Rindsberg, Andrew: I live 30 miles away from Moscow.

65
00:07:18.410 --> 00:07:21.530
Rindsberg, Andrew: And I work at uw at the University of West Alabama.

66
00:07:23.090 --> 00:07:29.120
Rindsberg, Andrew: So i've been there i've talked with the landowner i've talked with his previous land after.

67
00:07:30.440 --> 00:07:35.210
Rindsberg, Andrew: As well and i've looked into the property ownership situation.

68
00:07:36.230 --> 00:07:45.350
Rindsberg, Andrew: The only publicly own part of that outcrop that is visible that can be visited is the part immediately below the bridge and within.

69
00:07:46.490 --> 00:07:49.970
Rindsberg, Andrew: An easement around at 10 or 15 feet that's it.

70
00:07:51.050 --> 00:07:58.910
Rindsberg, Andrew: All of the outcrop that that chuck chuck is described is on private land, including.

71
00:08:01.100 --> 00:08:05.720
Rindsberg, Andrew: part that we normally would consider an Alabama to be public land along the river bank.

72
00:08:06.950 --> 00:08:11.600
Rindsberg, Andrew: But it's not long river bank it's a long an artificial lake bank.

73
00:08:12.830 --> 00:08:31.880
Rindsberg, Andrew: And the original property line goes right down to the original river bank which is now deeply submerged So if you look at a property ownership map it actually shows that he owns land that is some permanently submerged below the Tom big bear lake.

74
00:08:33.830 --> 00:08:44.090
Rindsberg, Andrew: Which means that it's vital to get the word out that people shouldn't just traipse around on this man's land, because he is touchy about it, but he does, let people go with permission.

75
00:08:46.610 --> 00:08:49.040
Rindsberg, Andrew: So we, we need to treat this one gently.

76
00:08:50.840 --> 00:08:58.370
Michael Thonis: I wasn't planning to go, but I just was wondering I just don't know enough about I don't spend enough time I haven't spent enough time in Alabama to know.

77
00:08:59.180 --> 00:09:10.910
Michael Thonis: How much how much exposure the Roosevelt crops, how much alcohol exposure there is so I didn't know if this is, you know really special that you can see the boundary because you can't see it anywhere else in Alabama.

78
00:09:11.600 --> 00:09:18.290
Rindsberg, Andrew: You can you can visit the boundary the easiest place to go, is it near a small town.

79
00:09:19.550 --> 00:09:22.280
Rindsberg, Andrew: About 30 miles to the east called Jefferson.

80
00:09:22.940 --> 00:09:26.390
Rindsberg, Andrew: uh huh but you'll have to take a shovel because.

81
00:09:27.740 --> 00:09:31.700
Rindsberg, Andrew: Country continually gets overgrown but you what you recognizes the clayton sand.

82
00:09:33.440 --> 00:09:40.760
Rindsberg, Andrew: Yes, keep sticking out, you can dig above and below that it's even fall, but if you have enough students to dig it out, please do.

83
00:09:41.570 --> 00:09:44.030
savrdce@auburn.edu: Okay, should even go a little further east.

84
00:09:46.280 --> 00:09:47.780
savrdce@auburn.edu: near brags.

85
00:09:48.860 --> 00:09:59.900
savrdce@auburn.edu: there's another exposure of katie boundary beneath actually add a new bridge that's kind of in the middle of nowhere.

86
00:10:01.190 --> 00:10:09.500
savrdce@auburn.edu: there's a clayton Sam body there, but I think that's a completely different orange and the katie boundary sands at moscow's.

87
00:10:09.530 --> 00:10:11.570
savrdce@auburn.edu: landing in the ones in Jefferson.

88
00:10:13.910 --> 00:10:24.170
Rindsberg, Andrew: So that are getting others on private land that Shell creek and, in this very meeting and see there was a skin to.

89
00:10:24.320 --> 00:10:24.770
savrdce@auburn.edu: josh.

90
00:10:24.800 --> 00:10:25.760
Rindsberg, Andrew: are starting with.

91
00:10:26.570 --> 00:10:27.920
Rindsberg, Andrew: Cash broussard yeah.

92
00:10:28.010 --> 00:10:28.190
savrdce@auburn.edu: yeah.

93
00:10:28.310 --> 00:10:30.110
Rindsberg, Andrew: yeah he's working with George Philips.

94
00:10:32.120 --> 00:10:36.110
Rindsberg, Andrew: They located a new outcropping and near starkville Mississippi.

95
00:10:38.030 --> 00:10:38.330
Michael Thonis: Good.

96
00:10:38.540 --> 00:10:39.650
Rindsberg, Andrew: Also, private land.

97
00:10:40.640 --> 00:10:45.590
savrdce@auburn.edu: yeah and one of those Sam bodies look like it's chock full of cereals altered.

98
00:10:46.280 --> 00:10:47.720
Rindsberg, Andrew: To preserve remarkable yeah.

99
00:10:51.320 --> 00:11:04.910
Michael Thonis: So that was I had one other question and i'll be quiet, but just how you kind of answered it a little bit, but how representative, if you look at the different look at the cloud formation, for example, how.

100
00:11:06.380 --> 00:11:18.590
Michael Thonis: How much does that change as you go, you know horizontally through the through the formation from you know across I mean I looked at the math it looks like it's very extensive.

101
00:11:19.520 --> 00:11:27.260
Michael Thonis: Is it is your site is it the site in this in this field trip, you know, is it special or is it really quite typical.

102
00:11:27.770 --> 00:11:39.680
savrdce@auburn.edu: I think it's a more difficult site, I think, in the field trip, we talked about the thickness of the quaint information in central Alabama where it's actually differentiated.

103
00:11:40.220 --> 00:11:55.370
savrdce@auburn.edu: into the pine Baron Member and the mcbride limestone Member, and then the pine Baron Member in central Alabama there are, I would say 20 or so morrow limestone couplets very similar to the ones.

104
00:11:56.840 --> 00:11:59.180
savrdce@auburn.edu: In the lower part of the clayton and.

105
00:12:00.200 --> 00:12:10.760
savrdce@auburn.edu: i've always kind of viewed them as sort of, say, you only have maybe four or five meters of the same type of sediment whereas you have 27 meters or Molar.

106
00:12:11.150 --> 00:12:17.570
savrdce@auburn.edu: In the pine Barry Member and i've always kind of thought of those is sort of down lapping Paris sequence.

107
00:12:18.140 --> 00:12:33.080
savrdce@auburn.edu: That maybe down lapping on to some sort of surface of maximum starvation, so I think that the mosque landing section, where the quaintness much thinner I think it's much it's more disturbing than then in central Alabama.

108
00:12:36.260 --> 00:12:36.620
mm hmm.

109
00:12:41.330 --> 00:12:44.510
Michael Thonis: In a one last question similar to all those questions is.

110
00:12:45.980 --> 00:12:48.860
Michael Thonis: Is you mentioned, I think, in the prairie bluff.

111
00:12:50.240 --> 00:12:57.320
Michael Thonis: chalk, you know it's very shallow in fact probably exposed to above above sea level at some points above water level at some points.

112
00:12:58.940 --> 00:13:05.120
Michael Thonis: But I didn't I couldn't pick up how deep it might it might be below the surface of the water.

113
00:13:08.030 --> 00:13:11.600
savrdce@auburn.edu: main at the time of deposition or when it was eroded.

114
00:13:11.990 --> 00:13:18.350
Michael Thonis: What is that no, no, at the time the deposition you right like what what would have been the typical deposition yeah.

115
00:13:20.300 --> 00:13:23.960
savrdce@auburn.edu: I think that's it might have been 10s of meters.

116
00:13:24.500 --> 00:13:26.540
Michael Thonis: tensorflow API under 100 meters.

117
00:13:26.750 --> 00:13:31.490
savrdce@auburn.edu: Under a guest so and it's only because we have that admixed sand.

118
00:13:33.320 --> 00:13:49.130
savrdce@auburn.edu: and presumably the shelf was influenced periodically by storms, where you had discrete sand layers being deposited storm beds, but because it's so strata graphically condense that that thorough buyer probation is totally admixed.

119
00:13:50.600 --> 00:13:51.080
savrdce@auburn.edu: The.

120
00:13:52.280 --> 00:13:58.550
savrdce@auburn.edu: booze basically with all of the the classic detritus that were shared in periodically.

121
00:14:00.950 --> 00:14:10.220
savrdce@auburn.edu: yeah what I thought you were asking about was erosion at the top of the prayer bluff which is it's interesting because if you look at the Alabama state map.

122
00:14:12.560 --> 00:14:22.040
savrdce@auburn.edu: And angie correct me if i'm wrong, but a little bit further to the east of the Moscow landing area, the prairie bluff is absent.

123
00:14:23.270 --> 00:14:25.520
savrdce@auburn.edu: it's completely eroded, I think the lower.

124
00:14:25.520 --> 00:14:28.760
savrdce@auburn.edu: paleocene is sitting on the ripley if i'm not mistaken.

125
00:14:29.000 --> 00:14:30.260
savrdce@auburn.edu: At least that's the way it's.

126
00:14:30.260 --> 00:14:30.890
mapped.

127
00:14:31.970 --> 00:14:41.270
Rindsberg, Andrew: The haven't seen anywhere where it's missing, all together, but at the type locality of Perry bluff and so here on the Alabama river.

128
00:14:42.530 --> 00:14:45.080
Rindsberg, Andrew: It is almost missing it's very it's.

129
00:14:46.310 --> 00:14:47.420
Rindsberg, Andrew: been nine feet thick.

130
00:14:49.400 --> 00:14:50.090
Michael Thonis: And you think.

131
00:14:50.120 --> 00:14:54.710
Michael Thonis: And you think eroded not it was there, but then eroded.

132
00:14:55.070 --> 00:14:57.170
Rindsberg, Andrew: I think it's been condensed it's.

133
00:14:57.200 --> 00:14:58.520
Rindsberg, Andrew: chock full of shells.

134
00:14:59.120 --> 00:15:00.110
Michael Thonis: And at that point.

135
00:15:01.880 --> 00:15:02.720
Rindsberg, Andrew: it's it's.

136
00:15:03.740 --> 00:15:07.190
Rindsberg, Andrew: So typical week we named the.

137
00:15:07.790 --> 00:15:09.980
Rindsberg, Andrew: Before nation for one of the least typical.

138
00:15:12.080 --> 00:15:12.830
Rindsberg, Andrew: disclosures.

139
00:15:13.160 --> 00:15:24.530
Michael Thonis: Completely true here in Boston we've got a number of famous formations, you know that are hugely visible everywhere except that the tight locality, you know.

140
00:15:25.550 --> 00:15:28.250
Michael Thonis: But that's where someone did the original work right right.

141
00:15:28.700 --> 00:15:33.950
savrdce@auburn.edu: But getting back Mike to one of your earlier comments about exposures and coastal plain.

142
00:15:35.000 --> 00:15:43.250
savrdce@auburn.edu: Overall, I mean, given our climate in the associated vegetation exposures and the coastal plain are not very good so.

143
00:15:44.030 --> 00:16:02.930
savrdce@auburn.edu: We have some local typically short road cut exposures, but a lot of times we rely on on the rivers and then of course we're, we have to rely on discharge and flooding, and what that does to accessibility.

144
00:16:04.250 --> 00:16:12.590
Michael Thonis: it's just that it's a shame in ways that the places that are close to if if you know the meteor the media or is that.

145
00:16:13.640 --> 00:16:17.390
Michael Thonis: Media right media or if the asteroid is the is the culprit here.

146
00:16:19.640 --> 00:16:22.820
Michael Thonis: which I think you have evidence that it has a role it plays a role in this.

147
00:16:24.200 --> 00:16:29.870
Michael Thonis: It may play a significant role in this it's just a shame that the outcrops are hardest to find right.

148
00:16:31.520 --> 00:16:40.250
Michael Thonis: I mean, even the right, even the asteroid itself is buried, but I mean even but all of these all of these sites that could be.

149
00:16:41.840 --> 00:16:50.930
Michael Thonis: places where they were where they were or large title were large tsunamis may have occurred or not particularly great across.

150
00:16:51.770 --> 00:17:01.040
Michael Thonis: And that's kind of true almost everywhere, I think most of the well I don't want to say i'll just I think that places like Cuba is where you see more evidence of mega tsunami.

151
00:17:03.620 --> 00:17:07.550
Michael Thonis: But it doesn't mean it couldn't have happened were you were you are right.

152
00:17:08.450 --> 00:17:17.630
savrdce@auburn.edu: yeah how crops are isolated, there are a number of places like brazos river in Texas in several places, and I think northern Mexico that.

153
00:17:18.800 --> 00:17:22.490
savrdce@auburn.edu: yeah we're we have Sam bodies that are dear the case, excuse me.

154
00:17:25.700 --> 00:17:29.930
savrdce@auburn.edu: That are invariably interpreted related to the impact.

155
00:17:30.170 --> 00:17:31.370
Michael Thonis: yeah yeah well.

156
00:17:31.520 --> 00:17:39.950
Rindsberg, Andrew: we're in a much better situation for this and Alabama than we are and and most of the rest of the Gulf remley have more outcrops.

157
00:17:41.480 --> 00:17:50.810
Rindsberg, Andrew: denser a number of decent crops and elsewhere and Compare that to say the lower Chesapeake impact crater.

158
00:17:51.500 --> 00:17:52.550
Rindsberg, Andrew: Only nothing ever.

159
00:17:52.760 --> 00:17:54.140
Rindsberg, Andrew: happened well drilling for.

160
00:17:54.860 --> 00:17:55.130
Rindsberg, Andrew: Now.

161
00:17:55.970 --> 00:18:02.810
Michael Thonis: I should they survived I think they first advised, I think, based on tech tights and then do an analysis of.

162
00:18:03.050 --> 00:18:03.620
Rindsberg, Andrew: Oh that's right.

163
00:18:03.950 --> 00:18:12.560
Michael Thonis: Where they might have come from, and is it Oh, and then drilling supported I don't know actually for sure, which came first, but I think I think it was first just looking at the tech tech field.

164
00:18:14.480 --> 00:18:15.710
Rindsberg, Andrew: Just as an aside.

165
00:18:17.180 --> 00:18:19.490
Rindsberg, Andrew: Several years ago chuck's.

166
00:18:20.540 --> 00:18:23.000
Rindsberg, Andrew: Colleague at auburn David king.

167
00:18:26.450 --> 00:18:32.420
Rindsberg, Andrew: He organized a mini conference on the tonka impact crater of Alabama.

168
00:18:33.710 --> 00:18:36.530
Rindsberg, Andrew: Which is not related to the sheep sulu impact.

169
00:18:38.150 --> 00:18:50.540
Rindsberg, Andrew: Its owners, he yeah he it's still involved as cretaceous but it's older and he brought in people from all over the world, who had studied impact craters and since I lived in Alabama I went.

170
00:18:51.980 --> 00:18:52.400
Michael Thonis: and

171
00:18:54.140 --> 00:19:01.340
Rindsberg, Andrew: Out of curiosity, I asked the participants, how many impact craters have you seen him, you know, everybody said, well, other than the weed tonka crater.

172
00:19:02.030 --> 00:19:14.060
Rindsberg, Andrew: And meteor crater out in Arizona i've seen the only the only other one i've seen is the one that I just just studied, so the Chesapeake people had only seen at most three craters.

173
00:19:14.480 --> 00:19:20.930
Rindsberg, Andrew: yeah ever and since I had been to meteor crater we chunk and.

174
00:19:22.700 --> 00:19:28.580
Rindsberg, Andrew: The whales creek structure in Tennessee I actually was right up there that rare.

175
00:19:30.230 --> 00:19:34.850
Rindsberg, Andrew: Most people it's like people studying ivory big build woodpeckers.

176
00:19:35.210 --> 00:19:44.540
Michael Thonis: yeah it's pretty rare looks like a pretty rare and I think that is the manson one in iowa, I think, which is smaller and then there's that one up in Quebec.

177
00:19:45.620 --> 00:19:47.780
Michael Thonis: The medic medic Coogan is it.

178
00:19:49.160 --> 00:19:58.760
Rindsberg, Andrew: My point is that, if you're studying the tsunami features and most people like like chuck who studied tsunami features have just seen the one.

179
00:19:59.210 --> 00:20:00.770
Rindsberg, Andrew: yeah right Am I correct.

180
00:20:01.940 --> 00:20:14.330
savrdce@auburn.edu: Well, I think I think that's been the issue all along is we we people talk about tsunami deposits and I kind of avoid that term I like mega way better for the katie boundaries.

181
00:20:14.780 --> 00:20:15.950
savrdce@auburn.edu: Because we have.

182
00:20:16.370 --> 00:20:22.190
savrdce@auburn.edu: No modern analogs for the the magnitude of.

183
00:20:22.250 --> 00:20:25.010
savrdce@auburn.edu: The event that occurred at the end of the quotations.

184
00:20:26.720 --> 00:20:39.440
savrdce@auburn.edu: And one of the things that bothered me early on, originally when I was looking at katie boundary Sections I focused on muscle creek and central Alabama and I was convinced it was a thin little insides valley film.

185
00:20:40.100 --> 00:20:59.390
savrdce@auburn.edu: yeah and so then moved out to Moscow landing and I fell into the trap where whatever these sans even though they're very different than the ones that muscle creek I had to try to pigeonhole them into my preconceived notion of what was going on.

186
00:21:00.860 --> 00:21:12.740
savrdce@auburn.edu: on the opposite side of the coin is because we have no modern analogs people good look at some of these katie boundary deposits in make observations and then interpret them.

187
00:21:14.240 --> 00:21:22.580
savrdce@auburn.edu: In terms of they were free to kind of interpret them in terms of what they perceive was going on in terms of some giant mega.

188
00:21:23.060 --> 00:21:38.570
savrdce@auburn.edu: mega wave event for which they had no matter modern analogues or no way of testing, but after spending more and more time that up Muscat landing I just can't see how you could explain.

189
00:21:39.590 --> 00:21:50.540
savrdce@auburn.edu: Those Sam bodies and other work in any other way than then to say that at least the lower parts of them were in place by some very large no wait.

190
00:21:52.940 --> 00:21:56.660
Sharon Browning: question here, someone who's who seen this site and.

191
00:21:58.580 --> 00:22:16.040
Sharon Browning: At the time, in my career was going to agree with whatever the Professor says i've watched your presentation twice, and I remember, noting an iridium layer in my notes and you didn't mention that in the video, and so I was curious about that.

192
00:22:16.970 --> 00:22:22.520
savrdce@auburn.edu: Note there was no I don't think anybody's documented any high concentration of iridium.

193
00:22:22.610 --> 00:22:22.970
At.

194
00:22:24.170 --> 00:22:38.660
savrdce@auburn.edu: Moscow landing if you go to muscle creek and there is a somewhat enrich the iridium layer just above the boundary but it's not a real big spike in it it's in a very, very, very cool oxygenated.

195
00:22:39.980 --> 00:22:40.970
Sharon Browning: Thought i'd missed that.

196
00:22:41.000 --> 00:22:44.150
Sharon Browning: But I had that in my original field notes.

197
00:22:44.390 --> 00:22:44.690
yeah.

198
00:22:46.610 --> 00:22:57.650
Michael Thonis: it's a great question I had wonder, the same thing, I know, though, that iridium you know it is a necessary thing that the iridium be distributed smoothly and evenly across the planet right.

199
00:22:58.310 --> 00:23:04.760
Michael Thonis: It could be and I don't know I don't know whether you've ever ever Is anyone ever founded radium close up to the.

200
00:23:06.080 --> 00:23:10.010
Michael Thonis: You know, to the to the suspect meteor asteroid.

201
00:23:11.660 --> 00:23:20.870
Michael Thonis: In fact isn't it sort of generally associated with some some plays of some sort i'm thinking of the brazos situation and I don't know much about it.

202
00:23:21.230 --> 00:23:30.830
savrdce@auburn.edu: yeah I mean it was originally discovered in a very fine grain pelagic mud rock that's how the whole thing got started and.

203
00:23:32.180 --> 00:23:42.770
savrdce@auburn.edu: But the one in central Alabama is it just not off the charts and it could easily be explained by very slow sedimentation yeah yeah.

204
00:23:46.010 --> 00:23:49.280
Michael Thonis: So you know, this is a little bit crazy but.

205
00:23:50.330 --> 00:23:53.540
Michael Thonis: But I was thinking about your surfing shrimp and.

206
00:23:54.890 --> 00:24:05.000
Michael Thonis: I actually showed the photo to my wife very cute i'm actually right now in Cape cod and we have we have we don't have shrimp, but we have a lot of borrowing things.

207
00:24:06.410 --> 00:24:16.790
Michael Thonis: crustaceans and mollusks and nothing and nothing really borrows quite as fast as you would need it to and your explanation, but I wondered.

208
00:24:18.230 --> 00:24:23.660
Michael Thonis: If if there was any chance that you have evidence they're not evidence, but.

209
00:24:25.100 --> 00:24:39.710
Michael Thonis: You know the suggestion of maybe that that the that the asteroid had baby to did they were two bodies, you know one right after the other one after a few hours after the other, and then i'd be people have talked about whether any of these bodies are.

210
00:24:40.940 --> 00:24:42.650
Michael Thonis: Fully intact when they hit.

211
00:24:43.670 --> 00:24:47.510
Michael Thonis: And I don't know whether that would have bought you know, maybe they were to sit on two mega.

212
00:24:48.620 --> 00:24:49.490
Michael Thonis: mega waves.

213
00:24:50.720 --> 00:24:50.930
savrdce@auburn.edu: well.

214
00:24:51.410 --> 00:24:55.130
Michael Thonis: That would have bought you enough time for those shrimp to borrow deeply enough.

215
00:24:55.370 --> 00:24:59.570
savrdce@auburn.edu: that's a good question, in fact, when we had submitted the paper.

216
00:25:00.590 --> 00:25:11.450
savrdce@auburn.edu: A couple years ago one of the reviewers comments were you know how do you have enough time if if for those shrimp to do you know the buyer debate those.

217
00:25:11.450 --> 00:25:14.240
savrdce@auburn.edu: interviews and of course they're not completely homogenized is.

218
00:25:15.290 --> 00:25:31.700
savrdce@auburn.edu: There discrete burrows super imposed on laminated sand and, if you look into the literature, there are a variety of papers that described the Berlin rates of certain types of kalyan acid trim and it's highly variable but.

219
00:25:32.720 --> 00:25:40.490
savrdce@auburn.edu: some indication that they might borrow or up to 50 centimeters per hour or something like that.

220
00:25:41.390 --> 00:25:50.780
savrdce@auburn.edu: And the other thing, too, is that you got a try to put myself in a shrimp in the body of a shrimp that was just catastrophic Lee.

221
00:25:51.140 --> 00:26:05.540
savrdce@auburn.edu: transported by a mega wave and then lived to tell about it, I would imagine that that would have a significant impact on you know sort of helter skelter what the hell's going on i'm gonna burn really quickly to.

222
00:26:06.230 --> 00:26:07.280
savrdce@auburn.edu: be yes.

223
00:26:08.150 --> 00:26:13.700
savrdce@auburn.edu: And so I think there's enough evidence from the literature of modern shrimpton.

224
00:26:15.980 --> 00:26:22.250
savrdce@auburn.edu: The other side of that story, I should point out is that you know people have modeled the progress.

225
00:26:23.120 --> 00:26:31.940
savrdce@auburn.edu: Of the waves and it wasn't one big mega wave we had these waves oscillating back and forth across the proto Gulf of Mexico.

226
00:26:32.810 --> 00:26:54.110
savrdce@auburn.edu: And I think they indicated that the period one modeling paper that the period would be a bait about eight hours and so maybe there were periods of relative qui essence in between waves that these locks on a set that's what they are these pioneers.

227
00:26:55.490 --> 00:27:02.150
savrdce@auburn.edu: would have maybe an hour or a few hours to actually do the work we seem manifest those The lesson.

228
00:27:04.460 --> 00:27:14.510
Rindsberg, Andrew: Well, I don't think I don't I think this is that was the least plausible part of your your field trip but.

229
00:27:17.000 --> 00:27:18.380
Rindsberg, Andrew: Obviously the birds are there.

230
00:27:19.640 --> 00:27:28.970
Rindsberg, Andrew: An alternative hypothesis might be that they there aren't very many visible vertical shafts and that they are actually.

231
00:27:30.230 --> 00:27:40.730
Rindsberg, Andrew: They conquer and they preferred particular layers within the sand, for some reason, and we know that animals, sometimes do that it would all be it would still be peculiar because.

232
00:27:41.750 --> 00:27:46.850
Rindsberg, Andrew: they're like three basic layers and they have different segments illogical styles.

233
00:27:47.960 --> 00:27:48.830
Rindsberg, Andrew: As you've noticed.

234
00:27:49.850 --> 00:27:50.900
Rindsberg, Andrew: What i'd like to know is.

235
00:27:52.250 --> 00:27:59.690
Rindsberg, Andrew: The one at least the ones toward the top are filled with chalk, so I presume that if micro micro paleontologist.

236
00:28:01.460 --> 00:28:08.840
Rindsberg, Andrew: took scrapings from that they find clayton age material i'd like to know about the lower ones, though.

237
00:28:09.350 --> 00:28:10.670
Rindsberg, Andrew: Right so.

238
00:28:10.730 --> 00:28:11.570
Rindsberg, Andrew: that's festival.

239
00:28:12.050 --> 00:28:24.230
savrdce@auburn.edu: yeah and that's one of the things that I sorta was alluding to in terms of suggestions toward the end of the of the field trip but what's interesting is in both same body one in six.

240
00:28:25.580 --> 00:28:35.810
savrdce@auburn.edu: The same body six only has the one clearly defined layer and then that's I think equivalent to the upper layer at Sam body one.

241
00:28:37.400 --> 00:28:47.900
savrdce@auburn.edu: You have the penetrating across from the base of the clayton you have planar laminated sandstone that doesn't appear to be disrupted at all.

242
00:28:48.380 --> 00:28:57.860
savrdce@auburn.edu: And then you have an interval that's got more of a marley matrix and then you're back into parallel emanated sans that have the borough.

243
00:28:58.640 --> 00:29:07.520
savrdce@auburn.edu: And so it's my impression that the source horizon may actually be coming out of one of those Marty earlier intervals, which might suggest that.

244
00:29:07.880 --> 00:29:16.700
savrdce@auburn.edu: A little bit of a I don't want to say slack water but qui essence, where we had more time to maybe settle out some of the MIC right that got put into suspension.

245
00:29:17.870 --> 00:29:31.460
savrdce@auburn.edu: Excuse me if, in fact, that was related to to the mega waves, but I agonized in both of those same bodies, whether those were discrete buyer debated horizons and I hope we can get out there.

246
00:29:33.260 --> 00:29:35.810
savrdce@auburn.edu: And look at them together and.

247
00:29:36.080 --> 00:29:36.890
Rindsberg, Andrew: I would be nice.

248
00:29:38.480 --> 00:29:47.930
savrdce@auburn.edu: Because I argued with myself, you know, often and had to convince myself that those were discrete internal buyer debater horizons and.

249
00:29:49.130 --> 00:30:07.070
Rindsberg, Andrew: i've been well looking at your your slides I was planning to just delve into my memory of trying to remember what the field relations were, and it would be so easy to point to it and try to figure it out on on the outcrop yeah.

250
00:30:08.330 --> 00:30:08.810
Rindsberg, Andrew: But they.

251
00:30:09.860 --> 00:30:10.250
Rindsberg, Andrew: See.

252
00:30:11.270 --> 00:30:17.540
Rindsberg, Andrew: Have you taken then sections of the clayton sandstone I know it's pretty friable stuff.

253
00:30:18.230 --> 00:30:24.080
savrdce@auburn.edu: Like we have a we have a few things sections through upward through one of the.

254
00:30:25.460 --> 00:30:28.040
savrdce@auburn.edu: sand bodies now I can't remember which number.

255
00:30:29.150 --> 00:30:34.640
savrdce@auburn.edu: And those samples were taken fairly early before we were actually numbering them.

256
00:30:36.290 --> 00:30:45.410
savrdce@auburn.edu: But they do vary texturally and they also vary significantly, I think the ones in the lower part primarily contain a.

257
00:30:47.180 --> 00:31:03.830
savrdce@auburn.edu: particular topic carbonate cements and then some of the other intervals, are more blocky or, in some cases it's a MIC right matrix summit, so the matrix the green size in the matrix do very.

258
00:31:05.300 --> 00:31:14.450
savrdce@auburn.edu: Through through the units one of the things that I think would be interesting, we we didn't do this is take a closer look at sediment technology, for example.

259
00:31:15.650 --> 00:31:21.410
savrdce@auburn.edu: same body one or any of the same bodies, I mean they're clearly deposition will units.

260
00:31:22.760 --> 00:31:28.820
savrdce@auburn.edu: And it would be interesting to see whether you can actually even though they're discreet Sam bodies, whether you could match up.

261
00:31:29.900 --> 00:31:36.950
savrdce@auburn.edu: texturally or fabric wise, because that would indicate that they're responding to the same.

262
00:31:38.060 --> 00:31:44.930
savrdce@auburn.edu: deposition process in these fault bounded depth of centers as opposed to oh you've got some near shore.

263
00:31:46.100 --> 00:31:48.110
savrdce@auburn.edu: sedimentation going on in these.

264
00:31:48.110 --> 00:31:49.160
savrdce@auburn.edu: flooded areas.

265
00:31:50.840 --> 00:31:52.670
savrdce@auburn.edu: And so I think that's something that.

266
00:31:53.780 --> 00:31:55.670
savrdce@auburn.edu: That that could be done.

267
00:31:56.810 --> 00:31:58.310
savrdce@auburn.edu: Look at a little bit more carefully.

268
00:31:59.300 --> 00:32:02.600
Rindsberg, Andrew: Another queue that I have is if.

269
00:32:04.130 --> 00:32:08.000
Rindsberg, Andrew: The bird is at the top of the co plane, or whatever, whatever you call it.

270
00:32:09.860 --> 00:32:21.470
Rindsberg, Andrew: they're doing much the same thing in the chalk, as they are in the sand and if the sound was loose, then why aren't they doing a few morphing the sand and the last night is in the chalk.

271
00:32:24.650 --> 00:32:25.010
savrdce@auburn.edu: that's.

272
00:32:25.130 --> 00:32:25.850
Rindsberg, Andrew: Why, why are they.

273
00:32:25.910 --> 00:32:29.450
Rindsberg, Andrew: Helping they're reinforcing their versus pay them.

274
00:32:30.200 --> 00:32:32.030
savrdce@auburn.edu: Well it's interesting question the.

275
00:32:33.830 --> 00:32:42.860
savrdce@auburn.edu: There they're clearly differences in overall morphology I think the ones where there's no clayton saying they tend to be more vertical.

276
00:32:45.590 --> 00:32:52.910
savrdce@auburn.edu: And so I would consider those things to represent firm grounds I don't see anything in the ones that are placed in the tops of the same bodies.

277
00:32:54.440 --> 00:33:03.110
savrdce@auburn.edu: It looks like they're just you know plain old the last annoyed ease and placed in a granular sand but getting back to your question is.

278
00:33:03.860 --> 00:33:23.720
savrdce@auburn.edu: If those things are being placed as the shore face migrates landward and the substrates they're being placed in aren't necessarily shifting and characterized by rapid erosion or rapid deposition maybe the crustaceans didn't need to tell it ties the other.

279
00:33:24.770 --> 00:33:29.630
savrdce@auburn.edu: potential problem is that most of the fields of those burrows have been washed out.

280
00:33:30.230 --> 00:33:32.240
savrdce@auburn.edu: yeah due to high water in the river.

281
00:33:32.660 --> 00:33:36.440
Rindsberg, Andrew: Yes, but you can see the chalk and then, if you look yeah for her.

282
00:33:38.360 --> 00:33:52.970
savrdce@auburn.edu: But, but I have one photograph that I took probably 15 years ago from Sam body six the one at the southern end where it actually so, and this would be in one of these lead internal.

283
00:33:53.510 --> 00:34:03.980
savrdce@auburn.edu: Fire debated horizons, there is one that has fluted engines that look for all the world like it was pelted in the pellets as well as the film were washed out.

284
00:34:05.450 --> 00:34:06.380
savrdce@auburn.edu: But it's only one.

285
00:34:07.520 --> 00:34:12.020
Rindsberg, Andrew: But this brings up another point I hadn't occurred to me until this moment.

286
00:34:13.850 --> 00:34:22.220
Rindsberg, Andrew: Okay you've got a mega wave has just brought in Washington sand and and shrimp the doomed pioneers.

287
00:34:23.750 --> 00:34:36.800
Rindsberg, Andrew: That sand is not fun, no, it does the shrimp couldn't this shrimp or as would have collapsed, but this was saying that had been deposited only hours before.

288
00:34:44.210 --> 00:34:45.320
savrdce@auburn.edu: I don't know why would.

289
00:34:46.910 --> 00:34:52.220
savrdce@auburn.edu: Why would they necessarily collapse, I mean we see a crust the shrimp burrows in.

290
00:34:53.510 --> 00:34:56.450
savrdce@auburn.edu: The last and he's in near shore sans.

291
00:34:56.930 --> 00:35:03.650
Rindsberg, Andrew: These would be sensitive been deposited only hours before it would be fixed Tropic it'd be very.

292
00:35:05.870 --> 00:35:06.320
Rindsberg, Andrew: wet.

293
00:35:09.080 --> 00:35:09.290
savrdce@auburn.edu: well.

294
00:35:09.770 --> 00:35:11.420
savrdce@auburn.edu: I don't know how fix a tropical.

295
00:35:11.570 --> 00:35:15.350
savrdce@auburn.edu: Be that's an interesting point, though, so.

296
00:35:17.210 --> 00:35:19.580
savrdce@auburn.edu: You just don't like my megaliths surfing.

297
00:35:22.850 --> 00:35:24.590
Rindsberg, Andrew: Just looked so normal.

298
00:35:26.060 --> 00:35:27.470
Rindsberg, Andrew: there's too much of them.

299
00:35:28.340 --> 00:35:39.740
Michael Thonis: The sand bodies or or maybe they're if they're fought fall down they might be drink me they may be an orientation to the overall were there, or just coincidentally on this site.

300
00:35:40.310 --> 00:35:56.030
Michael Thonis: The six or four on the site that were there drain where they drain or they may just be dipping the actual the actual fault Valley, the valley created by the faulty maybe just draining you know in some direction and drying fairly quickly.

301
00:35:56.450 --> 00:35:58.340
Rindsberg, Andrew: move would also be under the sea.

302
00:35:59.420 --> 00:35:59.870
Michael Thonis: yeah.

303
00:36:01.160 --> 00:36:01.550
savrdce@auburn.edu: resume.

304
00:36:02.000 --> 00:36:04.160
Michael Thonis: that's right yeah that's right see.

305
00:36:04.850 --> 00:36:18.020
savrdce@auburn.edu: One of the things I mean john Smith, who also interprets the wedge shapes and bodies as as related to mega wave deposition one of the things that he didn't consider.

306
00:36:20.150 --> 00:36:20.900
savrdce@auburn.edu: Is that.

307
00:36:22.310 --> 00:36:27.980
savrdce@auburn.edu: If they pray bluff clayton contact is a sequence boundary.

308
00:36:29.150 --> 00:36:35.090
savrdce@auburn.edu: And if there are no one size valley feels and it's a Co plane or transgressive sequence boundary.

309
00:36:36.260 --> 00:36:49.910
savrdce@auburn.edu: sea level had to a fall sometime before deposition of the clayton sand, and so the question is when the mega waves if assuming mega waves, the positive.

310
00:36:50.960 --> 00:36:53.060
savrdce@auburn.edu: All or parts of the same bodies.

311
00:36:54.110 --> 00:37:06.380
savrdce@auburn.edu: What was the sea level and i'm not saying that prairie bluff had to been severely exposed but sea level had to have fallen in the lake rotations.

312
00:37:09.140 --> 00:37:24.530
Michael Thonis: I was thinking sub Ariel exposed between the between the mega waves, because you know when there's a mega wave it the way it pulls all the water back away from away from the shoreline puts the shoreline way out.

313
00:37:26.090 --> 00:37:40.910
Michael Thonis: It just that's watching videos you know things like that Japan tsunami or the tsunami in the Indian Ocean, where it's just a huge amount of water just disappears goes out 30 miles and then come back with a vengeance.

314
00:37:41.660 --> 00:37:42.740
Rindsberg, Andrew: I don't know we know how.

315
00:37:43.490 --> 00:37:43.850
hard.

316
00:37:45.110 --> 00:37:49.550
Rindsberg, Andrew: i'm sorry I don't think anyone knows truly how high the wave was.

317
00:37:49.610 --> 00:37:53.390
Michael Thonis: No right right i'm just thinking about several possibility and.

318
00:37:54.590 --> 00:38:01.850
Michael Thonis: These these and these shrimp are scrambling to get down to you know below the water table locally.

319
00:38:02.870 --> 00:38:09.650
Michael Thonis: And you've got eight hours to do it, and I know is that I don't know enough about this topic, but does that who knows right.

320
00:38:11.690 --> 00:38:12.890
Rindsberg, Andrew: Not a geophysicist.

321
00:38:15.980 --> 00:38:16.460
savrdce@auburn.edu: Things.

322
00:38:16.640 --> 00:38:19.490
savrdce@auburn.edu: do with it, when the argument became Okay, are these.

323
00:38:20.810 --> 00:38:34.340
savrdce@auburn.edu: mega wave deposits or they thin little in size valley feels I mean insides me how he feels let's say in the western interior, where you had greater substance and more accommodation space they're up to 10s if not hundreds of meters.

324
00:38:36.080 --> 00:38:40.400
savrdce@auburn.edu: The sand bodies are probably no more than two meters stick, but if you.

325
00:38:41.870 --> 00:38:49.100
savrdce@auburn.edu: How do you get an inside Valley, to you, you have sea level fall subfertile exposure and erosion.

326
00:38:50.300 --> 00:38:53.600
savrdce@auburn.edu: And then during the initial transgression.

327
00:38:54.650 --> 00:39:04.700
savrdce@auburn.edu: As base levels rise you fill in those depressions and then the short face comes through well now let's take a mega wave.

328
00:39:06.800 --> 00:39:12.800
savrdce@auburn.edu: The trough of the mega wave hits first so you have withdrawal of the sea.

329
00:39:14.060 --> 00:39:16.100
savrdce@auburn.edu: And then, as the.

330
00:39:18.050 --> 00:39:21.800
savrdce@auburn.edu: The first mega wave comes running through.

331
00:39:23.090 --> 00:39:24.080
savrdce@auburn.edu: You could.

332
00:39:25.430 --> 00:39:30.740
savrdce@auburn.edu: conceivably feel these depressions in this case, they were produced by faulting if we said.

333
00:39:31.940 --> 00:39:33.860
savrdce@auburn.edu: Moscow landing and then.

334
00:39:34.910 --> 00:39:43.490
savrdce@auburn.edu: That erosion will surface at the top could potentially have something to do with the the mega which so to me it's like this the mega wave model could almost.

335
00:39:44.570 --> 00:39:47.900
savrdce@auburn.edu: be a sped up version of a sea levels.

336
00:39:48.830 --> 00:39:49.100
yeah.

337
00:39:50.330 --> 00:39:50.600
Rindsberg, Andrew: yeah.

338
00:39:51.140 --> 00:39:51.920
Rindsberg, Andrew: You could have.

339
00:39:54.050 --> 00:40:05.150
Rindsberg, Andrew: Okay you've got the Sheikh shalhoub impact that's going to generate the granddaddy of all earthquakes, so the faults are formed before the tsunamis hit several hours later.

340
00:40:07.010 --> 00:40:22.400
Michael Thonis: mm hmm yeah they're happening almost simultaneously with that well not simultaneously but pretty quickly after the event, I should I don't know that due to mega waves travel faster than seismic waves I think they travel more slowly, I think.

341
00:40:23.090 --> 00:40:24.980
Michael Thonis: Ours our slogan.

342
00:40:25.670 --> 00:40:33.230
Rindsberg, Andrew: She actually would have been what 900 miles south of here I think about 1000 miles.

343
00:40:35.660 --> 00:40:38.450
savrdce@auburn.edu: I wouldn't hazard a guess have to look at a map.

344
00:40:39.110 --> 00:40:42.380
Michael Thonis: I think that sounds right but you're in your in your geophysicist so you.

345
00:40:43.670 --> 00:40:44.600
Rindsberg, Andrew: said what you said earlier.

346
00:40:44.840 --> 00:40:45.890
Michael Thonis: So how fast would.

347
00:40:47.150 --> 00:40:58.460
Michael Thonis: plus or minus a few hundred miles, what would you know kilometers what would how fast does it take for the seismic the first seismic waves to arrive, not long right.

348
00:40:59.990 --> 00:41:01.460
Rindsberg, Andrew: Hours hours.

349
00:41:01.490 --> 00:41:04.700
Scott Brande: yeah well the the the propagation of.

350
00:41:06.200 --> 00:41:13.040
Scott Brande: Body waves and the crust is somewhere around call it, five, six kilometres per second and.

351
00:41:13.100 --> 00:41:15.590
Scott Brande: The segment of the tsunami waves.

352
00:41:16.040 --> 00:41:24.020
Scott Brande: are only about four to 450 miles an hour so as as Andy said it's it's a huge difference.

353
00:41:25.040 --> 00:41:30.500
Scott Brande: In the transmission time between the head of the seismic wave and the head of the the ocean wave.

354
00:41:31.130 --> 00:41:47.030
Michael Thonis: So the series of events could be the impact, then the huge mega earthquake, you know which breaks up at least the surface, and these are probably semi liquefied right materials right and.

355
00:41:48.260 --> 00:41:48.770
Michael Thonis: And then.

356
00:41:50.000 --> 00:41:56.900
Michael Thonis: And then the next event happens is that the way the water pulls out like a like a regression just pulls way out.

357
00:41:57.680 --> 00:42:11.300
Michael Thonis: And then, and then hours later comes back with a vengeance, and that probably repeats a few times meanwhile the shrimp you know they're like have no idea what's going on right, but all they know is that every time you get a chance, he just borrow down.

358
00:42:13.610 --> 00:42:13.940
Rindsberg, Andrew: well.

359
00:42:15.050 --> 00:42:16.190
Rindsberg, Andrew: there's your walk and get away.

360
00:42:16.280 --> 00:42:17.060
savrdce@auburn.edu: My theory.

361
00:42:20.060 --> 00:42:29.450
Rindsberg, Andrew: I like Superman additional evidence for you some things that you may not have been able to see because I had somewhat different experiences at the side.

362
00:42:30.680 --> 00:42:31.250
Rindsberg, Andrew: But that's.

363
00:42:32.360 --> 00:42:40.730
Rindsberg, Andrew: Instead of poking at your weak point let's i'm going to i'm going to strengthen your already strong point okay.

364
00:42:42.500 --> 00:42:53.570
Rindsberg, Andrew: bear with me i've got more than one point here one of them, the faults, I have more than once, gone down on a boat trip from demonic lists to Moscow landing.

365
00:42:55.190 --> 00:43:00.950
Rindsberg, Andrew: On the Tom baby river at the marvelous the faults are few and displacement is like.

366
00:43:01.610 --> 00:43:21.440
Rindsberg, Andrew: As you go farther South the displacement the faults become more numerous and the displacement displacement gets greater until you get to Moscow landing and virtually every KPMG site now Alabama I don't know about brags but as far as I know, all of the others are faulted.

367
00:43:24.380 --> 00:43:32.930
Rindsberg, Andrew: including some that are now permanently underwater destroyed by eugene Allen Smith in the in the 1800s I can't bluff.

368
00:43:34.190 --> 00:43:37.400
Rindsberg, Andrew: So this these folks are not local.

369
00:43:38.690 --> 00:43:45.530
Rindsberg, Andrew: This you can pretty much assume that the whole coastal plain of Alabama got faulted and I think simultaneously.

370
00:43:48.050 --> 00:43:56.060
Rindsberg, Andrew: Okay, so that's one strengthening piece of evidence, another is the caitlyn the cobbles of chalk.

371
00:43:58.130 --> 00:44:17.180
Rindsberg, Andrew: They are the wrong shape to be formed in local creeks and rivers i've been on many creeks and rivers and Alabama and if that child was anything like the chocolate today, maybe a little less less liquefied it should be shaped in slabs.

372
00:44:18.620 --> 00:44:32.540
Rindsberg, Andrew: They tend to get plucked up in the in the creeks and then moved if they're broken down much further they're not slabs anymore or or blocks or rectangular blocks that are often joint bound rounded.

373
00:44:34.250 --> 00:44:44.960
Rindsberg, Andrew: Rather than these very rounded looking cobbles that you see at Moscow landing, I simply don't believe that there's a river process that could produce that shape of chalk.

374
00:44:46.700 --> 00:44:51.080
Rindsberg, Andrew: So we've got something else, those that truck rolled.

375
00:44:52.370 --> 00:44:57.680
Rindsberg, Andrew: Okay, what we should be looking for is armory of these giant clay balls.

376
00:45:00.050 --> 00:45:10.820
Rindsberg, Andrew: Another feature that some of this chalk day breathe some of it quite course is actually injected down into these faults that Moscow landing.

377
00:45:12.650 --> 00:45:15.950
Rindsberg, Andrew: That means that those faults moved exactly once.

378
00:45:18.110 --> 00:45:21.710
Rindsberg, Andrew: and did not otherwise there's chalk cobbles would today be smeared.

379
00:45:24.560 --> 00:45:33.620
Rindsberg, Andrew: So yes, some of the faults did continue to move in the paleocene I think that's clear, but some of them moved once.

380
00:45:35.240 --> 00:45:36.680
Rindsberg, Andrew: During a disaster.

381
00:45:38.480 --> 00:45:42.020
Scott Brande: And a with regard to those boulders if you will.

382
00:45:43.190 --> 00:45:49.310
Scott Brande: Is there any petrol graphic analysis of the.

383
00:45:50.630 --> 00:45:52.580
Scott Brande: interior of those.

384
00:45:56.960 --> 00:45:58.460
Scott Brande: is just a partners or cobbles.

385
00:45:58.700 --> 00:46:02.030
Scott Brande: versus verte couples versus.

386
00:46:03.110 --> 00:46:08.360
Scott Brande: The matrix which would be within a couple of centimeters outside I mean i'm i'm trying to picture.

387
00:46:10.370 --> 00:46:11.690
Scott Brande: The degree to which.

388
00:46:12.800 --> 00:46:15.170
Scott Brande: The chalk held together.

389
00:46:16.580 --> 00:46:17.570
Scott Brande: In a.

390
00:46:19.010 --> 00:46:20.540
Scott Brande: In a mechanical way.

391
00:46:21.620 --> 00:46:24.800
Scott Brande: As different from the surrounding matrix.

392
00:46:25.400 --> 00:46:32.030
Rindsberg, Andrew: I certainly haven't done any such studies Oh, there was one other thing to notice that was john smith's.

393
00:46:33.350 --> 00:46:36.800
Rindsberg, Andrew: Observation he he found and i'm.

394
00:46:37.880 --> 00:46:54.020
Rindsberg, Andrew: jack has confirmed that there were three main pebble to cut cobbled two double beds there, they are finding upwards, each one it's as if there was a way there's another wave and he had a third wave, how many more ways we don't know.

395
00:46:56.660 --> 00:46:58.820
Rindsberg, Andrew: But as far as cryptography goes.

396
00:46:59.870 --> 00:47:01.130
Rindsberg, Andrew: it's an open field.

397
00:47:02.240 --> 00:47:09.530
savrdce@auburn.edu: And it's interesting too, because in some of those wedge shaped bodies it's clear that there was a fault scarf.

398
00:47:10.550 --> 00:47:31.850
savrdce@auburn.edu: And those class were more or less being check that probably coming over the top, but those the work and glamour attic intervals, then, can shout generally to the north, depending what Sam body are looking looking at so they're probably all sorts of other things that could be.

399
00:47:33.020 --> 00:47:34.880
savrdce@auburn.edu: done to try to fill in.

400
00:47:37.190 --> 00:47:37.430
savrdce@auburn.edu: In.

401
00:47:40.580 --> 00:47:41.300
Rindsberg, Andrew: This important.

402
00:47:42.710 --> 00:47:47.000
Rindsberg, Andrew: there's there's not another outcrop it's so expensive that shows all these features.

403
00:47:50.270 --> 00:47:54.140
Sharon Browning: For saving, I want to get out to Moscow landing again anytime this year.

404
00:47:56.750 --> 00:47:57.350
savrdce@auburn.edu: Maybe.

405
00:48:00.140 --> 00:48:03.650
savrdce@auburn.edu: I haven't been out there now and and probably over a year.

406
00:48:05.690 --> 00:48:06.350
savrdce@auburn.edu: Colvin.

407
00:48:07.400 --> 00:48:13.820
savrdce@auburn.edu: And the property situation kind of hit I was under the impression that the.

408
00:48:15.170 --> 00:48:24.380
savrdce@auburn.edu: And Andy clarified this at the beginning of our session but I had the misunderstanding that property lines or high water.

409
00:48:25.220 --> 00:48:39.350
savrdce@auburn.edu: mark and also there is a the gas pipeline that goes through the River there's a an access for utility and thinking that that was also public right away, and as Andy described before.

410
00:48:40.940 --> 00:48:42.950
savrdce@auburn.edu: I was wrong, it had been trespass.

411
00:48:46.670 --> 00:48:52.220
savrdce@auburn.edu: And so I think if we make the right connections Andy has already started and.

412
00:48:54.410 --> 00:48:56.660
savrdce@auburn.edu: I may try to introduce myself and.

413
00:48:58.040 --> 00:48:59.390
savrdce@auburn.edu: Give them a glossy.

414
00:49:00.470 --> 00:49:09.440
savrdce@auburn.edu: balloon up map strip napa there shoreline maybe that would use a dad of the call the COPs and say how did you do this with that trespassing them I.

415
00:49:10.970 --> 00:49:12.650
Michael Thonis: don't have the sweet occupies of that one.

416
00:49:13.100 --> 00:49:19.790
Rindsberg, Andrew: Well, I when I talked to him, like, I had a field trip and co and he said, what are you doing here.

417
00:49:21.980 --> 00:49:26.840
Rindsberg, Andrew: There I was at the bridge and we had quite a discussion I he left he, let us go.

418
00:49:29.690 --> 00:49:42.350
Rindsberg, Andrew: But I think mostly it was his honor that was being that he was thinking about he does, I don't think he really cares about all these field trips, as long as people ask for permission ahead time.

419
00:49:43.010 --> 00:49:52.280
Michael Thonis: Was, you know as long as you know, find a whole a whole tire and osiris fossil you know in there because that's that's out West right wyoming in.

420
00:49:53.300 --> 00:49:55.250
Rindsberg, Andrew: The code and that would be the kiss of death.

421
00:49:55.430 --> 00:49:56.240
Michael Thonis: yeah nobody.

422
00:49:56.570 --> 00:50:02.150
Michael Thonis: will know rancher will it just doesn't happen anymore, they will not give you access on the properties.

423
00:50:02.810 --> 00:50:06.440
Sharon Browning: But I wonder to about a liability issue because, if I remember that.

424
00:50:06.500 --> 00:50:09.260
Sharon Browning: Ben riverbank can be pretty slippery.

425
00:50:09.260 --> 00:50:11.270
Rindsberg, Andrew: Sometimes, yes yeah he was.

426
00:50:11.330 --> 00:50:12.470
Rindsberg, Andrew: He was concerned about.

427
00:50:13.130 --> 00:50:16.490
Rindsberg, Andrew: I wrote a handwritten liability waiver and.

428
00:50:16.490 --> 00:50:18.410
Rindsberg, Andrew: Had everyone sign it on the spot.

429
00:50:19.370 --> 00:50:20.360
Yes, that better.

430
00:50:21.740 --> 00:50:23.930
Michael Thonis: picture, do you have a do you have a.

431
00:50:24.980 --> 00:50:33.320
Michael Thonis: Full a composite of photographs of the I can't remember I don't think I saw that in the video of your strip map, but you have.

432
00:50:35.330 --> 00:50:37.610
Michael Thonis: Like you know what I mean a panorama.

433
00:50:39.290 --> 00:50:39.800
savrdce@auburn.edu: know.

434
00:50:41.420 --> 00:50:45.320
savrdce@auburn.edu: When I first started working out their digital cameras or.

435
00:50:45.950 --> 00:50:47.000
Michael Thonis: yeah yeah.

436
00:50:47.330 --> 00:50:56.510
savrdce@auburn.edu: And in order to try to sketch what we were seeing we dragged a canoe down there and I took an old polaroid camera.

437
00:50:58.250 --> 00:51:08.120
savrdce@auburn.edu: And as we floated down the river right, and so, and then what we did was put overlays on that sketched it so that the geometry is a little distorted but.

438
00:51:11.900 --> 00:51:15.380
savrdce@auburn.edu: We have some cross sectional view sketches that we've done but.

439
00:51:16.460 --> 00:51:19.880
savrdce@auburn.edu: It would have been neat to do a you know, to get a drone out there.

440
00:51:20.240 --> 00:51:25.940
Michael Thonis: Well, I was just thinking about my museum of science, you know how that would make a great Ural.

441
00:51:27.440 --> 00:51:34.370
Michael Thonis: In health people understand get us, you know it, you know, point out that we don't know sure what happened, but one possibility is.

442
00:51:35.450 --> 00:51:45.980
Michael Thonis: As supported, partly by this panorama this mural is the following story which I just think it's kind of you know you always wanting to museum to be as scintillating as possible yeah.

443
00:51:46.070 --> 00:51:58.850
savrdce@auburn.edu: Well, given the scale and the length of minutes, one point Gomez two kilometers long and and the outcrops Andy what maximum five meters in any one place if you.

444
00:51:59.090 --> 00:52:01.910
savrdce@auburn.edu: Had a whole panorama you wouldn't be able to see.

445
00:52:02.330 --> 00:52:09.950
Michael Thonis: No, but you know what these digital which you can do with these digital photos, as you can change the scales, you know, however, often the trial set.

446
00:52:09.950 --> 00:52:10.580
savrdce@auburn.edu: stretch it out.

447
00:52:10.880 --> 00:52:13.700
Michael Thonis: Well, you know the Cross section, you might have you know five X.

448
00:52:14.000 --> 00:52:14.240
savrdce@auburn.edu: yeah.

449
00:52:14.360 --> 00:52:20.030
Michael Thonis: On the vertical you can do that, you can actually do that with a with you know by digitizing it.

450
00:52:21.500 --> 00:52:31.070
Michael Thonis: And i've seen actually were there's a name for it, but the you can take separate photos and then using software stitch them together like you're just one.

451
00:52:32.330 --> 00:52:39.800
Michael Thonis: Like one large panoramic photo it's got huge detail, you know the pixels are terrific.

452
00:52:40.490 --> 00:52:42.440
Sharon Browning: Are you talking about like a giga pan.

453
00:52:42.590 --> 00:52:46.760
Michael Thonis: yeah good Japan that's it, thank you, the giga pan yeah that that technology.

454
00:52:46.850 --> 00:52:47.540
Van Burbach: i'm gonna have to.

455
00:52:48.950 --> 00:52:49.310
Michael Thonis: deal.

456
00:52:49.460 --> 00:52:49.910
With thanks.

457
00:52:53.750 --> 00:52:59.660
Michael Thonis: So that would you know you can really grateful i'm just i'm just thinking of maybe maybe i'll make contact you at some point.

458
00:53:00.770 --> 00:53:03.740
Michael Thonis: and go on a field trip with you and we'll get all the right permissions.

459
00:53:05.690 --> 00:53:06.980
Rindsberg, Andrew: That would be so wonder.

460
00:53:08.300 --> 00:53:09.710
Rindsberg, Andrew: It should be done on a.

461
00:53:10.790 --> 00:53:12.950
Rindsberg, Andrew: On a day when the river is flat so.

462
00:53:14.810 --> 00:53:15.200
Michael Thonis: Low.

463
00:53:15.260 --> 00:53:18.860
Rindsberg, Andrew: The drones you're right with drones you wouldn't matter with it.

464
00:53:20.270 --> 00:53:20.570
Rindsberg, Andrew: wow.

465
00:53:21.920 --> 00:53:28.490
savrdce@auburn.edu: Well, I think it'd be hard to settle the issue of the mega wave surfing shrimp using a drone I think.

466
00:53:29.180 --> 00:53:30.740
savrdce@auburn.edu: We need to get our nose right on.

467
00:53:30.740 --> 00:53:31.130
savrdce@auburn.edu: The good.

468
00:53:33.050 --> 00:53:49.520
Scott Brande: hey chuck i'm going to have to go shortly, but I just wanted to bring back, maybe a memory that I have held strongly since 1996 and specifically in May and you might You might remember whoops, how can I do this.

469
00:53:50.750 --> 00:53:51.830
Sharon Browning: Virtual background.

470
00:53:52.400 --> 00:53:55.400
Scott Brande: Yes, buddy oh there it is.

471
00:53:55.460 --> 00:53:57.080
Michael Thonis: Okay dad dinosaurs.

472
00:53:57.260 --> 00:54:10.190
Scott Brande: dead dead dead dinosaurs right, and this is when yeah i'll see if I can get this this is when Walter Alvarez came to Alabama for his one.

473
00:54:11.930 --> 00:54:21.230
Scott Brande: Guided field trip with you, and what I did is since a friend of mine was writing for the burnham news Jeff handsome.

474
00:54:22.130 --> 00:54:38.180
Scott Brande: came along on the trip and I brought to Birmingham City school teachers and so we had a wonderful time with you as you were leading one of your your local field trips down there may may of 1996.

475
00:54:39.260 --> 00:54:42.560
Scott Brande: And and Alvarez apparently enjoyed it greatly at that time.

476
00:54:45.980 --> 00:54:47.810
savrdce@auburn.edu: Are you are you talking to Andy.

477
00:54:48.440 --> 00:54:49.160
Scott Brande: No i'm talking.

478
00:54:49.250 --> 00:54:50.990
Scott Brande: i'm talking to you chuck.

479
00:54:51.470 --> 00:54:57.890
savrdce@auburn.edu: Oh well, i'll take credit for, but I think I would Alvarez, on a future down there so.

480
00:54:58.280 --> 00:54:59.330
Scott Brande: yeah well.

481
00:55:01.220 --> 00:55:01.610
Scott Brande: well.

482
00:55:03.080 --> 00:55:03.920
Sharon Browning: shoemaker.

483
00:55:04.550 --> 00:55:05.180
Scott Brande: It definitely.

484
00:55:05.570 --> 00:55:06.290
Rindsberg, Andrew: wasn't me.

485
00:55:07.610 --> 00:55:08.000
Michael Thonis: well.

486
00:55:09.560 --> 00:55:12.110
savrdce@auburn.edu: crowded Charlie Charlie Smith navy.

487
00:55:13.820 --> 00:55:16.580
Scott Brande: Was Charlie the one who argued against.

488
00:55:17.690 --> 00:55:18.560
Rindsberg, Andrew: Yes.

489
00:55:18.620 --> 00:55:21.350
Rindsberg, Andrew: Yes, and he's he's a nano expert.

490
00:55:22.460 --> 00:55:27.320
Rindsberg, Andrew: I don't know what he's doing now, but he says that eventually he wants his ashes, to be spread at Moscow.

491
00:55:28.850 --> 00:55:30.290
Scott Brande: Oh good Lord.

492
00:55:32.330 --> 00:55:32.720
Scott Brande: well.

493
00:55:33.770 --> 00:55:41.330
Scott Brande: In any case, i've got the head off, but thanks for the incredible graphics and the photographs as well chuck so I really appreciate it.

494
00:55:41.540 --> 00:55:44.060
Michael Thonis: Thanks, thank you, thank you chuck i'm gonna go to thank you.

495
00:55:44.300 --> 00:55:44.870
savrdce@auburn.edu: Mike Thank you.

496
00:55:48.500 --> 00:55:48.950
Rindsberg, Andrew: well.

497
00:55:56.510 --> 00:56:15.050
Sharon Browning: But preserving, it is an issue because I remember seeing the ups site just off of air base boulevard and and that's gone now because it took that CAP rock for the zoo and that meat or scale cross stratification that was preserved there yeah I think it was the utah formation.

498
00:56:16.040 --> 00:56:17.600
savrdce@auburn.edu: yeah the topic be saying.

499
00:56:17.870 --> 00:56:20.570
Rindsberg, Andrew: Suddenly, so the River outcrops are.

500
00:56:20.600 --> 00:56:30.380
Rindsberg, Andrew: Self renewing in a way, I mean it's a subtracted process, the fact is, you can go there many times and see something different, every time you go.

501
00:56:30.620 --> 00:56:30.950
Oh, you.

502
00:56:33.740 --> 00:56:34.490
savrdce@auburn.edu: know the.

503
00:56:36.020 --> 00:56:48.560
savrdce@auburn.edu: you're talking about preservation, I thought, what this may be a harebrained idea and Andy I think you were highly involved in the what is the Union Chapel mind is that the right.

504
00:56:50.330 --> 00:56:51.230
Rindsberg, Andrew: One time yes.

505
00:56:51.410 --> 00:56:54.200
savrdce@auburn.edu: yeah in terms of getting that preserved.

506
00:56:55.340 --> 00:56:57.260
savrdce@auburn.edu: Is that state property now right.

507
00:56:58.250 --> 00:56:59.270
Rindsberg, Andrew: It is.

508
00:56:59.870 --> 00:57:08.390
savrdce@auburn.edu: i'm just wondering whether we could figure out a way of preserving a strip of the Moscow landing section.

509
00:57:11.180 --> 00:57:12.920
savrdce@auburn.edu: Through a similar type of effort.

510
00:57:15.830 --> 00:57:19.100
Rindsberg, Andrew: It would be very different the Union Chapel mine was.

511
00:57:20.090 --> 00:57:21.440
Rindsberg, Andrew: A whole line of being shot.

512
00:57:21.440 --> 00:57:24.350
Rindsberg, Andrew: down, so the.

513
00:57:26.900 --> 00:57:35.780
Rindsberg, Andrew: Congress had to had to interfere, because it was because there was a federal law sayings inactive minds, have to be covered over again.

514
00:57:37.220 --> 00:57:45.020
Rindsberg, Andrew: So they had to make an exception, we got support from at her fault, one of our State Representatives.

515
00:57:48.050 --> 00:57:51.800
Rindsberg, Andrew: This and it was private property, and then I.

516
00:57:53.060 --> 00:58:02.660
Rindsberg, Andrew: I don't know how much money the other owners were given that they got something from the state I don't know how we've managed to do this in this.

517
00:58:02.690 --> 00:58:06.530
savrdce@auburn.edu: Is yeah I thought there was some sort of fundraising effort that actually.

518
00:58:06.530 --> 00:58:07.970
Rindsberg, Andrew: got better was.

519
00:58:08.330 --> 00:58:16.010
savrdce@auburn.edu: It to some degree, this could potentially be simpler, because you don't have the coal mining regulation.

520
00:58:18.020 --> 00:58:26.780
savrdce@auburn.edu: And it's kind of like you know just up to the edge of the woods, what are they going to do at that those nicely exposed products.

521
00:58:27.860 --> 00:58:42.620
savrdce@auburn.edu: And then they wouldn't have to worry about liability and it could be, it could be administered similar to the way the Herald station, or something like that is where it's through University of Alabama or something like that so.

522
00:58:45.860 --> 00:58:50.450
savrdce@auburn.edu: So there is some control on accessed but.

523
00:58:51.920 --> 00:59:00.410
savrdce@auburn.edu: And there be some sort of central clearing house or something that that let people in or gotten lucky or whatever, but.

524
00:59:02.900 --> 00:59:09.680
Rindsberg, Andrew: You who operates as a sumter county nature trust on.

525
00:59:10.700 --> 00:59:12.920
Rindsberg, Andrew: And through that they operate.

526
00:59:14.630 --> 00:59:35.000
Rindsberg, Andrew: A site on the River on an old bluff part it actually includes the type locality of the bluff part our own, although that was not their intention it's an archaeological site and it includes the laughs along the river, I could look into that and see how that was done.

527
00:59:36.470 --> 00:59:39.260
Rindsberg, Andrew: And that would be one avenue you.

528
00:59:41.300 --> 00:59:42.740
Rindsberg, Andrew: could also see that we could.

529
00:59:43.910 --> 00:59:45.710
Rindsberg, Andrew: go through the nature conservancy.

530
00:59:47.270 --> 00:59:54.680
Rindsberg, Andrew: which has a huge amount of experience in talking with landowners and soothing their ruffled feathers and.

531
00:59:56.030 --> 01:00:02.870
Rindsberg, Andrew: And sometimes leaving land in their hands, but within a kind of an easement.

532
01:00:04.400 --> 01:00:04.760
Rindsberg, Andrew: That.

533
01:00:06.470 --> 01:00:09.620
Rindsberg, Andrew: restrict certain kind of usage they do this with.

534
01:00:11.000 --> 01:00:14.420
Rindsberg, Andrew: Oh endangered plants, for instance.

535
01:00:15.530 --> 01:00:21.380
Rindsberg, Andrew: so that you know they might have an easement on a field and say you can hunt there all you like just just don't.

536
01:00:22.430 --> 01:00:24.440
Rindsberg, Andrew: Just don't plow it and use it for crops, you know.

537
01:00:25.250 --> 01:00:32.330
savrdce@auburn.edu: I guess if I was the property owner, I think that my biggest issue is one that Sharon mentioned was is the liability.

538
01:00:34.220 --> 01:00:42.320
savrdce@auburn.edu: And so you know you you filled out those had students sign it, but you know i've been told by lawyers that you know.

539
01:00:43.340 --> 01:00:47.660
savrdce@auburn.edu: Laughter have some that may not be worth the paper they're written on.

540
01:00:48.560 --> 01:00:49.520
Rindsberg, Andrew: Why do we have them.

541
01:00:50.390 --> 01:00:52.760
savrdce@auburn.edu: Question just to make us feel better.

542
01:00:55.460 --> 01:00:56.600
savrdce@auburn.edu: My understanding is.

543
01:00:57.050 --> 01:00:58.070
Sharon Browning: due diligence.

544
01:00:59.180 --> 01:01:05.960
savrdce@auburn.edu: My understanding is and I got a contact Nick to our state geologist who was the one that.

545
01:01:06.980 --> 01:01:15.440
savrdce@auburn.edu: Supposedly it's been communicating with the property owner, in the meantime early on, when I found out about the issue of access.

546
01:01:16.130 --> 01:01:35.450
savrdce@auburn.edu: I had a draft our people here are legal folks put together a draft and that might be something that I need to show the property owner to see whether that would suffice, but I know they've been communicating with the lawyers themselves about the liability issue and so.

547
01:01:36.680 --> 01:01:38.420
savrdce@auburn.edu: they're they're not just.

548
01:01:39.800 --> 01:01:46.430
savrdce@auburn.edu: now know off the cuff well we're concerned somebody might get hurt they're communicating bleak with legal counsel about it.

549
01:01:47.720 --> 01:02:04.010
Sharon Browning: Well, one other completely different topic question here, and then I have to go, do you see that I could see this easily being used for for undergraduates have you have you thought about I think I think this field trip is supposed to be made available on GSA website.

550
01:02:05.690 --> 01:02:06.560
Sharon Browning: Is that correct.

551
01:02:08.450 --> 01:02:10.700
savrdce@auburn.edu: audrey I don't know whether she's still listening.

552
01:02:11.630 --> 01:02:13.910
savrdce@auburn.edu: We were, I was asking about that, before.

553
01:02:14.810 --> 01:02:21.980
savrdce@auburn.edu: Apparently, this will remain in what archive for a year, so that anybody.

554
01:02:23.690 --> 01:02:31.580
savrdce@auburn.edu: Who registered already can go back and access, it is that correct or somebody could register for the meeting.

555
01:02:32.600 --> 01:02:40.310
savrdce@auburn.edu: Post meeting and access whatever recordings obsessions and field trips is that accurate.

556
01:02:40.640 --> 01:02:48.980
RISE GSA Audrey Heun: yep so so like anything on the meeting that we've recorded is going to be available for up to a year and then.

557
01:02:50.180 --> 01:02:57.830
RISE GSA Audrey Heun: you're since it was a pre recorded field trip we're actually going to archive that on the GSA website behind a member of a member wall.

558
01:02:59.510 --> 01:03:09.350
RISE GSA Audrey Heun: for however long i'm not quite sure, since this is a new process for GSA we're still trying to figure out kind of that process so.

559
01:03:10.220 --> 01:03:19.580
RISE GSA Audrey Heun: I think there's for field trips from the southeast meeting that agreed to have it archives we're still trying to figure out exactly what that looks like and what does that mean.

560
01:03:20.330 --> 01:03:29.510
savrdce@auburn.edu: You know, one of the things early on, when I was trying to design a trip, I was trying to break it into segments where you would show part of it, and then say okay students.

561
01:03:30.170 --> 01:03:39.080
savrdce@auburn.edu: What did you just hear draw cross section and using strategy graphic principal sequence of events, try to figure out what's going on.

562
01:03:40.310 --> 01:03:59.810
savrdce@auburn.edu: But I think you still could introduce things the basic things like strata graphic principles and that sort of thing using polar parts of the trip, so if it's archived as long as somebody's a member, even though they weren't registered for the meeting, they would be able to access.

563
01:04:01.850 --> 01:04:02.480
savrdce@auburn.edu: At least for.

564
01:04:03.350 --> 01:04:11.780
Sharon Browning: myself thinking and in a way, I never imagined we've developed all this online content for our students and.

565
01:04:12.890 --> 01:04:18.860
Sharon Browning: And some of it is is really good and I don't see getting rid of it, especially for field experiences.

566
01:04:23.180 --> 01:04:23.990
Sharon Browning: Okay, I have.

567
01:04:24.020 --> 01:04:40.820
RISE GSA Audrey Heun: Yet and there's even then talk just you know kind of going forward with field trips, should we be sending professional photographers or videographers out there and really capturing everything that's a lot more money, but that is kind of the talk of like.

568
01:04:41.150 --> 01:04:41.540
RISE GSA Audrey Heun: Is this.

569
01:04:41.660 --> 01:04:49.910
RISE GSA Audrey Heun: Where are we going like what we you know covert hit we're dealing with it, how can we kind of continue to maybe.

570
01:04:50.930 --> 01:04:51.800
RISE GSA Audrey Heun: make things better.

571
01:04:53.840 --> 01:04:54.860
Sharon Browning: Thank you very much.

572
01:04:55.010 --> 01:04:55.340
savrdce@auburn.edu: No.

573
01:04:56.300 --> 01:04:58.160
Rindsberg, Andrew: Thank you, sharing, that was a great question.

574
01:05:01.880 --> 01:05:18.080
Rindsberg, Andrew: Well, you know discovering Alabama does have does does send out professionals into the field to do just very similarly thanks, but they're not doing it it's such a technical level, as you are checking.

575
01:05:20.450 --> 01:05:22.670
Rindsberg, Andrew: So I think would be that would be wonderful if you could.

576
01:05:22.760 --> 01:05:26.450
Rindsberg, Andrew: If you could get in touch with them with discovering Alabama Doug Phillips.

577
01:05:26.690 --> 01:05:35.870
savrdce@auburn.edu: yeah I can do with Doug Phillips, and took the sands of time, the mighty Tom big me river here flows southward across the coastal plain.

578
01:05:39.590 --> 01:05:43.010
Rindsberg, Andrew: Until it flowed backward and the great tsunami yeah.

579
01:05:43.910 --> 01:05:46.310
savrdce@auburn.edu: Maybe that's the voice, I should have done the field trip.

580
01:05:47.300 --> 01:05:49.310
RISE GSA Audrey Heun: To say where's the British British accent.

581
01:05:50.780 --> 01:05:52.610
Rindsberg, Andrew: What will know that you're doing.

582
01:05:52.640 --> 01:05:58.160
Rindsberg, Andrew: Real detailed work chuck when you tell us what season of the year, it happened in.

583
01:06:00.650 --> 01:06:06.530
Rindsberg, Andrew: i'll bet you can do it with if you look careful attention to the oyster growth lines.

584
01:06:19.940 --> 01:06:23.000
Rindsberg, Andrew: Actually, until I said it, I hadn't realized, it is actually possible.

585
01:06:26.810 --> 01:06:29.000
Rindsberg, Andrew: Well, that would make a great article in nature.

586
01:06:30.080 --> 01:06:34.460
savrdce@auburn.edu: Yes, yes, you draft it up send it to me and i'll add my part.

587
01:06:39.170 --> 01:06:47.030
savrdce@auburn.edu: Right any any other questions comments I think we've we've gone over and I don't know what time is the closing remarks that bill haynes's.

588
01:06:49.370 --> 01:06:57.020
RISE GSA Audrey Heun: I have to arrive at 425 mountain time, I think it starts at 545 central time okay.

589
01:06:59.870 --> 01:07:02.840
savrdce@auburn.edu: Any other questions comments so Terry john.

590
01:07:04.190 --> 01:07:04.730
savrdce@auburn.edu: So.

591
01:07:07.070 --> 01:07:10.370
John Fronimos: chuck I didn't have a lot of insights not being a.

592
01:07:11.990 --> 01:07:14.420
John Fronimos: You know somebody who does a lot with trace fossils but I did have.

593
01:07:15.260 --> 01:07:21.770
John Fronimos: One question I imagine you probably would have mentioned it if you'd seen something like this, when you talk about the you know the surfing shrimps and that sort of thing.

594
01:07:22.430 --> 01:07:33.050
John Fronimos: I immediately pictured you know here one of those shrimps that gets you know mixed up in the settlement and buried, would you see any signs of you know escaped traces or anything like that those.

595
01:07:34.460 --> 01:07:36.230
John Fronimos: persist in this type of stuff.

596
01:07:36.410 --> 01:07:42.050
savrdce@auburn.edu: that's a real good question um My guess is that the shrimp probably we're.

597
01:07:43.490 --> 01:07:46.730
savrdce@auburn.edu: Assuming that that's how they were in placed okay.

598
01:07:48.110 --> 01:08:04.220
savrdce@auburn.edu: They were probably more part of a suspended load than, although that Sam was probably in suspension to i'm just guessing that the sand might have come down before they the floating bodies of shrimp but.

599
01:08:06.290 --> 01:08:10.100
savrdce@auburn.edu: I don't know that's a interesting interesting point.

600
01:08:11.870 --> 01:08:20.900
savrdce@auburn.edu: Most of the time when you see escape structures they're usually produced by something that was already on the sea floor or when you had rapid deposition.

601
01:08:22.700 --> 01:08:34.730
savrdce@auburn.edu: But something like this probably would have had a lot of erosion prior to deposition and would have re suspended, you know just looking at regular storm deposits in the trace fossils.

602
01:08:35.870 --> 01:08:51.050
savrdce@auburn.edu: You would think you would find a lot more escape structures and then but I don't hardly ever seen him and I think it's because the base of the V San are typically sharp and original and either the current or the wave energy has reached suspended.

603
01:08:52.910 --> 01:08:55.670
savrdce@auburn.edu: The mud, and probably organisms.

604
01:08:56.720 --> 01:09:09.170
savrdce@auburn.edu: And then eventually you get the sand and then you have things fall out, you know the finer grain tail of the event, so I don't see a lot of I don't see any escape structures, although.

605
01:09:10.580 --> 01:09:16.460
savrdce@auburn.edu: it's kind of hard to see in these buyers for beta intervals, specifically in the quake sans good vertical.

606
01:09:18.170 --> 01:09:20.570
savrdce@auburn.edu: profile, so there are a few places where you can.

607
01:09:21.200 --> 01:09:25.400
Rindsberg, Andrew: I did look at the vertical profiles and I don't remember seeing any escape structures.

608
01:09:25.490 --> 01:09:28.460
Rindsberg, Andrew: or anything except for the last invitees.

609
01:09:28.700 --> 01:09:28.940
Right.

610
01:09:31.910 --> 01:09:38.000
savrdce@auburn.edu: What do you think about that audrey you buy in the mega wave surfing shrimp where's he going with Andy.

611
01:09:40.370 --> 01:09:42.200
Rindsberg, Andrew: i'm just being skeptical i'm not saying.

612
01:09:44.150 --> 01:09:46.100
savrdce@auburn.edu: i'm just trying to spot.

613
01:09:47.060 --> 01:09:50.000
RISE GSA Audrey Heun: These surfing transom quite interesting.

614
01:09:50.780 --> 01:09:55.910
savrdce@auburn.edu: Well, I didn't mention that we found the surfboards about that big it's.

615
01:09:58.340 --> 01:10:00.020
savrdce@auburn.edu: evolved been lignin ties, but.

616
01:10:01.340 --> 01:10:02.660
savrdce@auburn.edu: In board with to read oh.

617
01:10:03.920 --> 01:10:05.090
RISE GSA Audrey Heun: Yes, i'm making me hungry.

618
01:10:09.230 --> 01:10:09.410
RISE GSA Audrey Heun: I.

619
01:10:10.190 --> 01:10:19.370
Rindsberg, Andrew: guess i'm far from time to throw in the towel chuck Bravo, this was an excellent field trip video and the next Q amp a.

620
01:10:20.450 --> 01:10:29.060
savrdce@auburn.edu: And I think you helped make it that way, because you've been there and had a lot to add, I appreciate it, but let's get out there sometime.

621
01:10:31.880 --> 01:10:34.190
Rindsberg, Andrew: vantage this summer i've been vaccinated.

622
01:10:35.420 --> 01:10:38.240
savrdce@auburn.edu: I second one I got two weeks i'll get started.

623
01:10:40.640 --> 01:10:41.870
savrdce@auburn.edu: In the water should be down.

624
01:10:42.860 --> 01:10:44.150
Rindsberg, Andrew: yeah summer.

625
01:10:47.840 --> 01:10:49.700
Rindsberg, Andrew: home resting there in the summer, but.

626
01:10:49.790 --> 01:10:51.680
Rindsberg, Andrew: But to see the only good time to go.

627
01:10:54.140 --> 01:10:54.800
Rindsberg, Andrew: to slip on.

628
01:10:54.890 --> 01:10:56.630
Rindsberg, Andrew: That truck really is slick.

629
01:10:57.560 --> 01:10:57.800
yeah.

630
01:11:01.880 --> 01:11:02.840
RISE GSA Audrey Heun: So thank you.

631
01:11:02.900 --> 01:11:03.980
RISE GSA Audrey Heun: audrey yeah.

632
01:11:04.010 --> 01:11:05.960
RISE GSA Audrey Heun: Thank you fun working with you on this stuff.

633
01:11:06.200 --> 01:11:08.990
savrdce@auburn.edu: yeah thanks all of you guys at GSA it's.

634
01:11:10.220 --> 01:11:12.740
savrdce@auburn.edu: It seemed painless well thanks.

635
01:11:16.280 --> 01:11:24.500
John Fronimos: truck I wanted to say thank you being being new to the area, you know coming here this past year and still getting a feel for you know the.

636
01:11:25.130 --> 01:11:35.510
John Fronimos: locals photography and geology and things I was a great primer on a lot of them both the first photography and the the general the specific things that make this outcrop so interesting.

637
01:11:35.810 --> 01:11:37.700
Rindsberg, Andrew: Good Where are you located.

638
01:11:39.020 --> 01:11:49.460
John Fronimos: So i'm here at auburn now i'm a lecture on the department, but I just got hired this past fall mean down from vassar and so i'm crash coursing myself and.

639
01:11:50.540 --> 01:11:56.120
John Fronimos: You know I always like to get a feel for this retainer fee as fast as I can but it's sort of yeah.

640
01:11:56.480 --> 01:12:01.610
savrdce@auburn.edu: very long on retired in June, when I did run Louis.

641
01:12:03.350 --> 01:12:04.640
savrdce@auburn.edu: And he's been really hiding.

642
01:12:09.800 --> 01:12:11.090
Rindsberg, Andrew: Know darn you you move.

643
01:12:12.230 --> 01:12:17.330
Rindsberg, Andrew: Across country and during the pandemic and set up a new office and all everything.

644
01:12:17.960 --> 01:12:19.550
John Fronimos: That was interesting it was interesting.

645
01:12:21.170 --> 01:12:21.950
John Fronimos: It was probably about.

646
01:12:23.030 --> 01:12:34.910
John Fronimos: A little earlier than this last year that I was interviewing I was supposed to come down to auburn and then suddenly they said hey we're not traveling anymore rob you know reasons that we're quickly becoming obvious a.

647
01:12:37.130 --> 01:12:39.710
John Fronimos: little bit different from other other moves i've done.

648
01:12:41.510 --> 01:12:52.370
Rindsberg, Andrew: Well you're better off than the you who the biologists who almost became a member of our faculty our our hiring process just collapsed.

649
01:12:55.520 --> 01:12:58.640
John Fronimos: Right after I you know got this position, the.

650
01:13:00.050 --> 01:13:05.060
John Fronimos: You know, seeing that the job listing sort of dry up and things.

651
01:13:07.310 --> 01:13:08.690
savrdce@auburn.edu: Well we're glad you're here john.

652
01:13:13.400 --> 01:13:14.300
Rindsberg, Andrew: Welcome to Alabama.

653
01:13:15.980 --> 01:13:19.520
John Fronimos: Thanks i'm glad to be here glad to circuit and know the area.

654
01:13:21.230 --> 01:13:21.740
savrdce@auburn.edu: Okay.

655
01:13:22.490 --> 01:13:23.360
John Fronimos: So you actually get.

656
01:13:23.420 --> 01:13:25.250
Rindsberg, Andrew: Along with when chuck.

657
01:13:26.000 --> 01:13:28.280
Rindsberg, Andrew: comes together let's go come along.

658
01:13:29.060 --> 01:13:32.510
John Fronimos: i'm glad to come along on any any outing I can get.

659
01:13:35.810 --> 01:13:40.880
savrdce@auburn.edu: Well, I hope everybody has a good Easter weekend yeah I gotta go home and eat fish.

660
01:13:47.270 --> 01:13:47.840
Rindsberg, Andrew: Good fish.

661
01:13:49.910 --> 01:13:50.690
Rindsberg, Andrew: good night everyone.

662
01:13:52.400 --> 01:13:54.000
savrdce@auburn.edu: Thanks, for attending.

savrdce@auburn.edu: Thanks, for attending.

WEBVTT

1
00:00:00.001 --> 00:00:00.260
savrdce@auburn.edu: Little one go.

2
00:00:03.050 --> 00:00:11.240
RISE GSA Audrey Heun: yeah she she see if she gets like tired of me, being in here and then she'll come in and be like she wants to really be on the video screen.

3
00:00:13.310 --> 00:00:14.300
RISE GSA Audrey Heun: She really wants to.

4
00:00:14.960 --> 00:00:18.920
savrdce@auburn.edu: Be front and Center she just wants to learn something about quotations Paleo.

5
00:00:21.020 --> 00:00:24.410
RISE GSA Audrey Heun: There was um for the Northeast section, there was um.

6
00:00:25.670 --> 00:00:28.730
RISE GSA Audrey Heun: I think it's in Connecticut dinosaur national.

7
00:00:29.960 --> 00:00:33.140
RISE GSA Audrey Heun: Not there's like a national dinosaur museum.

8
00:00:34.580 --> 00:00:43.670
RISE GSA Audrey Heun: And they did this really cool field trip, and it was on a set it was on the weekend, so I made my kids sit with me we watched it and it was really fun so yeah.

9
00:00:44.720 --> 00:00:47.060
John Fronimos: Does that dinosaurs state park with the footprints.

10
00:00:47.180 --> 00:00:48.650
RISE GSA Audrey Heun: that's what it was yes.

11
00:00:49.970 --> 00:00:52.700
John Fronimos: And that's in Connecticut right and take classes up there yeah.

12
00:00:52.910 --> 00:00:55.820
RISE GSA Audrey Heun: yeah yeah they've been closed and so.

13
00:00:57.320 --> 00:01:13.550
RISE GSA Audrey Heun: A lot of things were a little different and they're kind of redoing a lot of different things, because they can right now with people not being there but they did a great job and they'd live stream did and have videos and they were like down crawling around and so it's really cool.

14
00:01:15.740 --> 00:01:25.820
Michael Thonis: yeah there's there's one of those in Connecticut and one of those Massachusetts both of them are in the well the hartford and the deerfield basins, those are the.

15
00:01:27.080 --> 00:01:29.360
Michael Thonis: Those are the the rift basins.

16
00:01:30.410 --> 00:01:31.340
Michael Thonis: mesozoic.

17
00:01:32.180 --> 00:01:33.920
savrdce@auburn.edu: Are they triassic or Jurassic.

18
00:01:34.730 --> 00:01:40.040
Michael Thonis: triassic I think 204 well I think yeah.

19
00:01:41.090 --> 00:01:45.110
John Fronimos: Thanks some of the track ways, or just up into the Jurassic.

20
00:01:45.350 --> 00:01:46.280
Michael Thonis: yeah I might be.

21
00:01:46.370 --> 00:01:51.890
Michael Thonis: that's why I hesitated but what's interesting is that there have been up there and he's been virtually no.

22
00:01:52.370 --> 00:02:03.710
Michael Thonis: almost no fossil bones found dinosaur bones found it's almost the entire there have been fossil fish found, but there are virtually it's almost entirely footprints.

23
00:02:04.310 --> 00:02:10.160
Michael Thonis: And there and they're in Massachusetts Massachusetts they're everywhere, you can go to the park, but you don't really need to.

24
00:02:11.330 --> 00:02:16.010
Michael Thonis: Because you can just walk out in the woods wherever you find it out crap there's footprints all over it.

25
00:02:17.060 --> 00:02:21.500
Michael Thonis: it's really astonishing and yet very few skeletal remains.

26
00:02:22.730 --> 00:02:26.060
Michael Thonis: And there's all kinds of theories about why you know why, why not.

27
00:02:28.040 --> 00:02:32.270
Michael Thonis: The museum is i'm with them i'm a trustee with museum of science in Boston and we.

28
00:02:33.470 --> 00:02:43.760
Michael Thonis: We, along with the state as a contest to two different species of dinosaur fossils that have been farewell footprints then a couple of pounds.

29
00:02:44.720 --> 00:02:56.960
Michael Thonis: Fossil bones, and we just just a month ago there was a contest and it was one of the most popular museum events ever it was to get people to name to choose which of the two.

30
00:02:59.240 --> 00:03:01.940
Michael Thonis: Which are the two dinosaurs would be the state dinosaur.

31
00:03:06.350 --> 00:03:09.110
Michael Thonis: And they were both cool they're both cool dinosaurs are small, but.

32
00:03:09.170 --> 00:03:09.650
Michael Thonis: You know.

33
00:03:09.860 --> 00:03:10.280
Very.

34
00:03:11.900 --> 00:03:16.700
savrdce@auburn.edu: Well, we have only 12 hey Scott there you're you're on the moon.

35
00:03:19.310 --> 00:03:20.000
savrdce@auburn.edu: up here.

36
00:03:21.140 --> 00:03:22.010
savrdce@auburn.edu: you're muted.

37
00:03:25.190 --> 00:03:26.630
Michael Thonis: Well, you can't hear anything on the moon.

38
00:03:26.720 --> 00:03:26.990
Saying.

39
00:03:29.600 --> 00:03:35.930
Scott Brande: hey look i'm a bit older than you so I figured 230,000 miles is efficient social distance in order.

40
00:03:39.800 --> 00:03:47.330
savrdce@auburn.edu: All right, well, it looks like we only have 12 out of the 53 attendees and I know at least a few of them told me they had.

41
00:03:48.500 --> 00:04:04.370
savrdce@auburn.edu: convene other sessions and that sort of thing, so I guess, we can get started, what I wanted what I wanted to do, though, before we actually to the Q amp a for the field trip is to acknowledge our sponsors.

42
00:04:08.150 --> 00:04:19.100
savrdce@auburn.edu: know a number of us were several hats for this meeting, and as as the sponsorship chair, I wanted to personally thank.

43
00:04:20.000 --> 00:04:39.680
savrdce@auburn.edu: The various sponsors for the meeting, and there are a number of corporate sponsors focused material southern company since Tara and Bob fossa comes with Fo sick mineral resources, incorporated and then of course we had excuse me, local support from our own department.

44
00:04:40.850 --> 00:04:46.610
savrdce@auburn.edu: Not only all the work that all the Faculty and students are doing, but some financial support for the meeting.

45
00:04:48.020 --> 00:04:56.750
savrdce@auburn.edu: Also, our college of science and mathematics here at auburn thank Dean Giordano, for his support and then we have a number of other.

46
00:04:57.920 --> 00:05:09.050
savrdce@auburn.edu: alumni and friends that are part of our auburn university geosciences advisory board that should be acknowledged for their their support as well, I also want to thank everybody.

47
00:05:10.070 --> 00:05:10.430
savrdce@auburn.edu: Who.

48
00:05:12.260 --> 00:05:20.390
savrdce@auburn.edu: put together sessions and led sessions, but also everybody who's participated in the in the meetings for those who attended.

49
00:05:21.740 --> 00:05:27.680
savrdce@auburn.edu: The meeting in the folks at GSA because I think they've they're handling this covert crisis.

50
00:05:28.880 --> 00:05:38.210
savrdce@auburn.edu: In a an incredible way and appreciate every everything they've done to help us get this rolling anyway i'll stop sharing the screen for now.

51
00:05:39.620 --> 00:05:53.540
savrdce@auburn.edu: And we can go ahead and and get started with our Q amp a hopefully everybody listening in received my email, I think I sent it on Wednesday evening, just to remind everybody that that.

52
00:05:54.410 --> 00:06:02.240
savrdce@auburn.edu: To get the most out of this session I guess it you really needed to kind of watch or attend the field trip beforehand.

53
00:06:03.350 --> 00:06:14.990
savrdce@auburn.edu: I apologize, that it was all pre recorded and and just kind of like a long very own PowerPoint presentation, it would have been nice obviously to visit the section which currently.

54
00:06:15.740 --> 00:06:23.180
savrdce@auburn.edu: Have katie boundary sands are about 40 feet underwater right now due to high discharge on the Tongue big be river.

55
00:06:24.440 --> 00:06:30.860
savrdce@auburn.edu: Of course coven would have kept us from getting out there and also some issues with access.

56
00:06:32.240 --> 00:06:41.510
savrdce@auburn.edu: To the exposure, but hopefully you got something out of it, hopefully, there were enough photographs and that sort of thing.

57
00:06:42.530 --> 00:06:46.520
savrdce@auburn.edu: That you found the trip informative anyway.

58
00:06:48.260 --> 00:06:50.060
savrdce@auburn.edu: But with that i'll just kind of.

59
00:06:51.500 --> 00:06:53.300
savrdce@auburn.edu: turn it over to kind of open it up.

60
00:06:53.960 --> 00:06:57.470
Michael Thonis: I know, on that point, the one you just made about the location.

61
00:06:57.980 --> 00:07:07.550
Michael Thonis: If I think you do mentioned in the video that there's a maybe something under a bridge somewhere, but is that it in terms of in terms of the boundary in that area.

62
00:07:09.200 --> 00:07:10.310
Rindsberg, Andrew: I can speak to that.

63
00:07:10.610 --> 00:07:12.950
savrdce@auburn.edu: yeah go ahead Andy Andy just communicated so.

64
00:07:14.480 --> 00:07:16.760
Rindsberg, Andrew: I live 30 miles away from Moscow.

65
00:07:18.410 --> 00:07:21.530
Rindsberg, Andrew: And I work at uw at the University of West Alabama.

66
00:07:23.090 --> 00:07:29.120
Rindsberg, Andrew: So i've been there i've talked with the landowner i've talked with his previous land after.

67
00:07:30.440 --> 00:07:35.210
Rindsberg, Andrew: As well and i've looked into the property ownership situation.

68
00:07:36.230 --> 00:07:45.350
Rindsberg, Andrew: The only publicly own part of that outcrop that is visible that can be visited is the part immediately below the bridge and within.

69
00:07:46.490 --> 00:07:49.970
Rindsberg, Andrew: An easement around at 10 or 15 feet that's it.

70
00:07:51.050 --> 00:07:58.910
Rindsberg, Andrew: All of the outcrop that that chuck chuck is described is on private land, including.

71
00:08:01.100 --> 00:08:05.720
Rindsberg, Andrew: part that we normally would consider an Alabama to be public land along the river bank.

72
00:08:06.950 --> 00:08:11.600
Rindsberg, Andrew: But it's not long river bank it's a long an artificial lake bank.

73
00:08:12.830 --> 00:08:31.880
Rindsberg, Andrew: And the original property line goes right down to the original river bank which is now deeply submerged So if you look at a property ownership map it actually shows that he owns land that is some permanently submerged below the Tom big bear lake.

74
00:08:33.830 --> 00:08:44.090
Rindsberg, Andrew: Which means that it's vital to get the word out that people shouldn't just traipse around on this man's land, because he is touchy about it, but he does, let people go with permission.

75
00:08:46.610 --> 00:08:49.040
Rindsberg, Andrew: So we, we need to treat this one gently.

76
00:08:50.840 --> 00:08:58.370
Michael Thonis: I wasn't planning to go, but I just was wondering I just don't know enough about I don't spend enough time I haven't spent enough time in Alabama to know.

77
00:08:59.180 --> 00:09:10.910
Michael Thonis: How much how much exposure the Roosevelt crops, how much alcohol exposure there is so I didn't know if this is, you know really special that you can see the boundary because you can't see it anywhere else in Alabama.

78
00:09:11.600 --> 00:09:18.290
Rindsberg, Andrew: You can you can visit the boundary the easiest place to go, is it near a small town.

79
00:09:19.550 --> 00:09:22.280
Rindsberg, Andrew: About 30 miles to the east called Jefferson.

80
00:09:22.940 --> 00:09:26.390
Rindsberg, Andrew: uh huh but you'll have to take a shovel because.

81
00:09:27.740 --> 00:09:31.700
Rindsberg, Andrew: Country continually gets overgrown but you what you recognizes the clayton sand.

82
00:09:33.440 --> 00:09:40.760
Rindsberg, Andrew: Yes, keep sticking out, you can dig above and below that it's even fall, but if you have enough students to dig it out, please do.

83
00:09:41.570 --> 00:09:44.030
savrdce@auburn.edu: Okay, should even go a little further east.

84
00:09:46.280 --> 00:09:47.780
savrdce@auburn.edu: near brags.

85
00:09:48.860 --> 00:09:59.900
savrdce@auburn.edu: there's another exposure of katie boundary beneath actually add a new bridge that's kind of in the middle of nowhere.

86
00:10:01.190 --> 00:10:09.500
savrdce@auburn.edu: there's a clayton Sam body there, but I think that's a completely different orange and the katie boundary sands at moscow's.

87
00:10:09.530 --> 00:10:11.570
savrdce@auburn.edu: landing in the ones in Jefferson.

88
00:10:13.910 --> 00:10:24.170
Rindsberg, Andrew: So that are getting others on private land that Shell creek and, in this very meeting and see there was a skin to.

89
00:10:24.320 --> 00:10:24.770
savrdce@auburn.edu: josh.

90
00:10:24.800 --> 00:10:25.760
Rindsberg, Andrew: are starting with.

91
00:10:26.570 --> 00:10:27.920
Rindsberg, Andrew: Cash broussard yeah.

92
00:10:28.010 --> 00:10:28.190
savrdce@auburn.edu: yeah.

93
00:10:28.310 --> 00:10:30.110
Rindsberg, Andrew: yeah he's working with George Philips.

94
00:10:32.120 --> 00:10:36.110
Rindsberg, Andrew: They located a new outcropping and near starkville Mississippi.

95
00:10:38.030 --> 00:10:38.330
Michael Thonis: Good.

96
00:10:38.540 --> 00:10:39.650
Rindsberg, Andrew: Also, private land.

97
00:10:40.640 --> 00:10:45.590
savrdce@auburn.edu: yeah and one of those Sam bodies look like it's chock full of cereals altered.

98
00:10:46.280 --> 00:10:47.720
Rindsberg, Andrew: To preserve remarkable yeah.

99
00:10:51.320 --> 00:11:04.910
Michael Thonis: So that was I had one other question and i'll be quiet, but just how you kind of answered it a little bit, but how representative, if you look at the different look at the cloud formation, for example, how.

100
00:11:06.380 --> 00:11:18.590
Michael Thonis: How much does that change as you go, you know horizontally through the through the formation from you know across I mean I looked at the math it looks like it's very extensive.

101
00:11:19.520 --> 00:11:27.260
Michael Thonis: Is it is your site is it the site in this in this field trip, you know, is it special or is it really quite typical.

102
00:11:27.770 --> 00:11:39.680
savrdce@auburn.edu: I think it's a more difficult site, I think, in the field trip, we talked about the thickness of the quaint information in central Alabama where it's actually differentiated.

103
00:11:40.220 --> 00:11:55.370
savrdce@auburn.edu: into the pine Baron Member and the mcbride limestone Member, and then the pine Baron Member in central Alabama there are, I would say 20 or so morrow limestone couplets very similar to the ones.

104
00:11:56.840 --> 00:11:59.180
savrdce@auburn.edu: In the lower part of the clayton and.

105
00:12:00.200 --> 00:12:10.760
savrdce@auburn.edu: i've always kind of viewed them as sort of, say, you only have maybe four or five meters of the same type of sediment whereas you have 27 meters or Molar.

106
00:12:11.150 --> 00:12:17.570
savrdce@auburn.edu: In the pine Barry Member and i've always kind of thought of those is sort of down lapping Paris sequence.

107
00:12:18.140 --> 00:12:33.080
savrdce@auburn.edu: That maybe down lapping on to some sort of surface of maximum starvation, so I think that the mosque landing section, where the quaintness much thinner I think it's much it's more disturbing than then in central Alabama.

108
00:12:36.260 --> 00:12:36.620
mm hmm.

109
00:12:41.330 --> 00:12:44.510
Michael Thonis: In a one last question similar to all those questions is.

110
00:12:45.980 --> 00:12:48.860
Michael Thonis: Is you mentioned, I think, in the prairie bluff.

111
00:12:50.240 --> 00:12:57.320
Michael Thonis: chalk, you know it's very shallow in fact probably exposed to above above sea level at some points above water level at some points.

112
00:12:58.940 --> 00:13:05.120
Michael Thonis: But I didn't I couldn't pick up how deep it might it might be below the surface of the water.

113
00:13:08.030 --> 00:13:11.600
savrdce@auburn.edu: main at the time of deposition or when it was eroded.

114
00:13:11.990 --> 00:13:18.350
Michael Thonis: What is that no, no, at the time the deposition you right like what what would have been the typical deposition yeah.

115
00:13:20.300 --> 00:13:23.960
savrdce@auburn.edu: I think that's it might have been 10s of meters.

116
00:13:24.500 --> 00:13:26.540
Michael Thonis: tensorflow API under 100 meters.

117
00:13:26.750 --> 00:13:31.490
savrdce@auburn.edu: Under a guest so and it's only because we have that admixed sand.

118
00:13:33.320 --> 00:13:49.130
savrdce@auburn.edu: and presumably the shelf was influenced periodically by storms, where you had discrete sand layers being deposited storm beds, but because it's so strata graphically condense that that thorough buyer probation is totally admixed.

119
00:13:50.600 --> 00:13:51.080
savrdce@auburn.edu: The.

120
00:13:52.280 --> 00:13:58.550
savrdce@auburn.edu: booze basically with all of the the classic detritus that were shared in periodically.

121
00:14:00.950 --> 00:14:10.220
savrdce@auburn.edu: yeah what I thought you were asking about was erosion at the top of the prayer bluff which is it's interesting because if you look at the Alabama state map.

122
00:14:12.560 --> 00:14:22.040
savrdce@auburn.edu: And angie correct me if i'm wrong, but a little bit further to the east of the Moscow landing area, the prairie bluff is absent.

123
00:14:23.270 --> 00:14:25.520
savrdce@auburn.edu: it's completely eroded, I think the lower.

124
00:14:25.520 --> 00:14:28.760
savrdce@auburn.edu: paleocene is sitting on the ripley if i'm not mistaken.

125
00:14:29.000 --> 00:14:30.260
savrdce@auburn.edu: At least that's the way it's.

126
00:14:30.260 --> 00:14:30.890
mapped.

127
00:14:31.970 --> 00:14:41.270
Rindsberg, Andrew: The haven't seen anywhere where it's missing, all together, but at the type locality of Perry bluff and so here on the Alabama river.

128
00:14:42.530 --> 00:14:45.080
Rindsberg, Andrew: It is almost missing it's very it's.

129
00:14:46.310 --> 00:14:47.420
Rindsberg, Andrew: been nine feet thick.

130
00:14:49.400 --> 00:14:50.090
Michael Thonis: And you think.

131
00:14:50.120 --> 00:14:54.710
Michael Thonis: And you think eroded not it was there, but then eroded.

132
00:14:55.070 --> 00:14:57.170
Rindsberg, Andrew: I think it's been condensed it's.

133
00:14:57.200 --> 00:14:58.520
Rindsberg, Andrew: chock full of shells.

134
00:14:59.120 --> 00:15:00.110
Michael Thonis: And at that point.

135
00:15:01.880 --> 00:15:02.720
Rindsberg, Andrew: it's it's.

136
00:15:03.740 --> 00:15:07.190
Rindsberg, Andrew: So typical week we named the.

137
00:15:07.790 --> 00:15:09.980
Rindsberg, Andrew: Before nation for one of the least typical.

138
00:15:12.080 --> 00:15:12.830
Rindsberg, Andrew: disclosures.

139
00:15:13.160 --> 00:15:24.530
Michael Thonis: Completely true here in Boston we've got a number of famous formations, you know that are hugely visible everywhere except that the tight locality, you know.

140
00:15:25.550 --> 00:15:28.250
Michael Thonis: But that's where someone did the original work right right.

141
00:15:28.700 --> 00:15:33.950
savrdce@auburn.edu: But getting back Mike to one of your earlier comments about exposures and coastal plain.

142
00:15:35.000 --> 00:15:43.250
savrdce@auburn.edu: Overall, I mean, given our climate in the associated vegetation exposures and the coastal plain are not very good so.

143
00:15:44.030 --> 00:16:02.930
savrdce@auburn.edu: We have some local typically short road cut exposures, but a lot of times we rely on on the rivers and then of course we're, we have to rely on discharge and flooding, and what that does to accessibility.

144
00:16:04.250 --> 00:16:12.590
Michael Thonis: it's just that it's a shame in ways that the places that are close to if if you know the meteor the media or is that.

145
00:16:13.640 --> 00:16:17.390
Michael Thonis: Media right media or if the asteroid is the is the culprit here.

146
00:16:19.640 --> 00:16:22.820
Michael Thonis: which I think you have evidence that it has a role it plays a role in this.

147
00:16:24.200 --> 00:16:29.870
Michael Thonis: It may play a significant role in this it's just a shame that the outcrops are hardest to find right.

148
00:16:31.520 --> 00:16:40.250
Michael Thonis: I mean, even the right, even the asteroid itself is buried, but I mean even but all of these all of these sites that could be.

149
00:16:41.840 --> 00:16:50.930
Michael Thonis: places where they were where they were or large title were large tsunamis may have occurred or not particularly great across.

150
00:16:51.770 --> 00:17:01.040
Michael Thonis: And that's kind of true almost everywhere, I think most of the well I don't want to say i'll just I think that places like Cuba is where you see more evidence of mega tsunami.

151
00:17:03.620 --> 00:17:07.550
Michael Thonis: But it doesn't mean it couldn't have happened were you were you are right.

152
00:17:08.450 --> 00:17:17.630
savrdce@auburn.edu: yeah how crops are isolated, there are a number of places like brazos river in Texas in several places, and I think northern Mexico that.

153
00:17:18.800 --> 00:17:22.490
savrdce@auburn.edu: yeah we're we have Sam bodies that are dear the case, excuse me.

154
00:17:25.700 --> 00:17:29.930
savrdce@auburn.edu: That are invariably interpreted related to the impact.

155
00:17:30.170 --> 00:17:31.370
Michael Thonis: yeah yeah well.

156
00:17:31.520 --> 00:17:39.950
Rindsberg, Andrew: we're in a much better situation for this and Alabama than we are and and most of the rest of the Gulf remley have more outcrops.

157
00:17:41.480 --> 00:17:50.810
Rindsberg, Andrew: denser a number of decent crops and elsewhere and Compare that to say the lower Chesapeake impact crater.

158
00:17:51.500 --> 00:17:52.550
Rindsberg, Andrew: Only nothing ever.

159
00:17:52.760 --> 00:17:54.140
Rindsberg, Andrew: happened well drilling for.

160
00:17:54.860 --> 00:17:55.130
Rindsberg, Andrew: Now.

161
00:17:55.970 --> 00:18:02.810
Michael Thonis: I should they survived I think they first advised, I think, based on tech tights and then do an analysis of.

162
00:18:03.050 --> 00:18:03.620
Rindsberg, Andrew: Oh that's right.

163
00:18:03.950 --> 00:18:12.560
Michael Thonis: Where they might have come from, and is it Oh, and then drilling supported I don't know actually for sure, which came first, but I think I think it was first just looking at the tech tech field.

164
00:18:14.480 --> 00:18:15.710
Rindsberg, Andrew: Just as an aside.

165
00:18:17.180 --> 00:18:19.490
Rindsberg, Andrew: Several years ago chuck's.

166
00:18:20.540 --> 00:18:23.000
Rindsberg, Andrew: Colleague at auburn David king.

167
00:18:26.450 --> 00:18:32.420
Rindsberg, Andrew: He organized a mini conference on the tonka impact crater of Alabama.

168
00:18:33.710 --> 00:18:36.530
Rindsberg, Andrew: Which is not related to the sheep sulu impact.

169
00:18:38.150 --> 00:18:50.540
Rindsberg, Andrew: Its owners, he yeah he it's still involved as cretaceous but it's older and he brought in people from all over the world, who had studied impact craters and since I lived in Alabama I went.

170
00:18:51.980 --> 00:18:52.400
Michael Thonis: and

171
00:18:54.140 --> 00:19:01.340
Rindsberg, Andrew: Out of curiosity, I asked the participants, how many impact craters have you seen him, you know, everybody said, well, other than the weed tonka crater.

172
00:19:02.030 --> 00:19:14.060
Rindsberg, Andrew: And meteor crater out in Arizona i've seen the only the only other one i've seen is the one that I just just studied, so the Chesapeake people had only seen at most three craters.

173
00:19:14.480 --> 00:19:20.930
Rindsberg, Andrew: yeah ever and since I had been to meteor crater we chunk and.

174
00:19:22.700 --> 00:19:28.580
Rindsberg, Andrew: The whales creek structure in Tennessee I actually was right up there that rare.

175
00:19:30.230 --> 00:19:34.850
Rindsberg, Andrew: Most people it's like people studying ivory big build woodpeckers.

176
00:19:35.210 --> 00:19:44.540
Michael Thonis: yeah it's pretty rare looks like a pretty rare and I think that is the manson one in iowa, I think, which is smaller and then there's that one up in Quebec.

177
00:19:45.620 --> 00:19:47.780
Michael Thonis: The medic medic Coogan is it.

178
00:19:49.160 --> 00:19:58.760
Rindsberg, Andrew: My point is that, if you're studying the tsunami features and most people like like chuck who studied tsunami features have just seen the one.

179
00:19:59.210 --> 00:20:00.770
Rindsberg, Andrew: yeah right Am I correct.

180
00:20:01.940 --> 00:20:14.330
savrdce@auburn.edu: Well, I think I think that's been the issue all along is we we people talk about tsunami deposits and I kind of avoid that term I like mega way better for the katie boundaries.

181
00:20:14.780 --> 00:20:15.950
savrdce@auburn.edu: Because we have.

182
00:20:16.370 --> 00:20:22.190
savrdce@auburn.edu: No modern analogs for the the magnitude of.

183
00:20:22.250 --> 00:20:25.010
savrdce@auburn.edu: The event that occurred at the end of the quotations.

184
00:20:26.720 --> 00:20:39.440
savrdce@auburn.edu: And one of the things that bothered me early on, originally when I was looking at katie boundary Sections I focused on muscle creek and central Alabama and I was convinced it was a thin little insides valley film.

185
00:20:40.100 --> 00:20:59.390
savrdce@auburn.edu: yeah and so then moved out to Moscow landing and I fell into the trap where whatever these sans even though they're very different than the ones that muscle creek I had to try to pigeonhole them into my preconceived notion of what was going on.

186
00:21:00.860 --> 00:21:12.740
savrdce@auburn.edu: on the opposite side of the coin is because we have no modern analogs people good look at some of these katie boundary deposits in make observations and then interpret them.

187
00:21:14.240 --> 00:21:22.580
savrdce@auburn.edu: In terms of they were free to kind of interpret them in terms of what they perceive was going on in terms of some giant mega.

188
00:21:23.060 --> 00:21:38.570
savrdce@auburn.edu: mega wave event for which they had no matter modern analogues or no way of testing, but after spending more and more time that up Muscat landing I just can't see how you could explain.

189
00:21:39.590 --> 00:21:50.540
savrdce@auburn.edu: Those Sam bodies and other work in any other way than then to say that at least the lower parts of them were in place by some very large no wait.

190
00:21:52.940 --> 00:21:56.660
Sharon Browning: question here, someone who's who seen this site and.

191
00:21:58.580 --> 00:22:16.040
Sharon Browning: At the time, in my career was going to agree with whatever the Professor says i've watched your presentation twice, and I remember, noting an iridium layer in my notes and you didn't mention that in the video, and so I was curious about that.

192
00:22:16.970 --> 00:22:22.520
savrdce@auburn.edu: Note there was no I don't think anybody's documented any high concentration of iridium.

193
00:22:22.610 --> 00:22:22.970
At.

194
00:22:24.170 --> 00:22:38.660
savrdce@auburn.edu: Moscow landing if you go to muscle creek and there is a somewhat enrich the iridium layer just above the boundary but it's not a real big spike in it it's in a very, very, very cool oxygenated.

195
00:22:39.980 --> 00:22:40.970
Sharon Browning: Thought i'd missed that.

196
00:22:41.000 --> 00:22:44.150
Sharon Browning: But I had that in my original field notes.

197
00:22:44.390 --> 00:22:44.690
yeah.

198
00:22:46.610 --> 00:22:57.650
Michael Thonis: it's a great question I had wonder, the same thing, I know, though, that iridium you know it is a necessary thing that the iridium be distributed smoothly and evenly across the planet right.

199
00:22:58.310 --> 00:23:04.760
Michael Thonis: It could be and I don't know I don't know whether you've ever ever Is anyone ever founded radium close up to the.

200
00:23:06.080 --> 00:23:10.010
Michael Thonis: You know, to the to the suspect meteor asteroid.

201
00:23:11.660 --> 00:23:20.870
Michael Thonis: In fact isn't it sort of generally associated with some some plays of some sort i'm thinking of the brazos situation and I don't know much about it.

202
00:23:21.230 --> 00:23:30.830
savrdce@auburn.edu: yeah I mean it was originally discovered in a very fine grain pelagic mud rock that's how the whole thing got started and.

203
00:23:32.180 --> 00:23:42.770
savrdce@auburn.edu: But the one in central Alabama is it just not off the charts and it could easily be explained by very slow sedimentation yeah yeah.

204
00:23:46.010 --> 00:23:49.280
Michael Thonis: So you know, this is a little bit crazy but.

205
00:23:50.330 --> 00:23:53.540
Michael Thonis: But I was thinking about your surfing shrimp and.

206
00:23:54.890 --> 00:24:05.000
Michael Thonis: I actually showed the photo to my wife very cute i'm actually right now in Cape cod and we have we have we don't have shrimp, but we have a lot of borrowing things.

207
00:24:06.410 --> 00:24:16.790
Michael Thonis: crustaceans and mollusks and nothing and nothing really borrows quite as fast as you would need it to and your explanation, but I wondered.

208
00:24:18.230 --> 00:24:23.660
Michael Thonis: If if there was any chance that you have evidence they're not evidence, but.

209
00:24:25.100 --> 00:24:39.710
Michael Thonis: You know the suggestion of maybe that that the that the asteroid had baby to did they were two bodies, you know one right after the other one after a few hours after the other, and then i'd be people have talked about whether any of these bodies are.

210
00:24:40.940 --> 00:24:42.650
Michael Thonis: Fully intact when they hit.

211
00:24:43.670 --> 00:24:47.510
Michael Thonis: And I don't know whether that would have bought you know, maybe they were to sit on two mega.

212
00:24:48.620 --> 00:24:49.490
Michael Thonis: mega waves.

213
00:24:50.720 --> 00:24:50.930
savrdce@auburn.edu: well.

214
00:24:51.410 --> 00:24:55.130
Michael Thonis: That would have bought you enough time for those shrimp to borrow deeply enough.

215
00:24:55.370 --> 00:24:59.570
savrdce@auburn.edu: that's a good question, in fact, when we had submitted the paper.

216
00:25:00.590 --> 00:25:11.450
savrdce@auburn.edu: A couple years ago one of the reviewers comments were you know how do you have enough time if if for those shrimp to do you know the buyer debate those.

217
00:25:11.450 --> 00:25:14.240
savrdce@auburn.edu: interviews and of course they're not completely homogenized is.

218
00:25:15.290 --> 00:25:31.700
savrdce@auburn.edu: There discrete burrows super imposed on laminated sand and, if you look into the literature, there are a variety of papers that described the Berlin rates of certain types of kalyan acid trim and it's highly variable but.

219
00:25:32.720 --> 00:25:40.490
savrdce@auburn.edu: some indication that they might borrow or up to 50 centimeters per hour or something like that.

220
00:25:41.390 --> 00:25:50.780
savrdce@auburn.edu: And the other thing, too, is that you got a try to put myself in a shrimp in the body of a shrimp that was just catastrophic Lee.

221
00:25:51.140 --> 00:26:05.540
savrdce@auburn.edu: transported by a mega wave and then lived to tell about it, I would imagine that that would have a significant impact on you know sort of helter skelter what the hell's going on i'm gonna burn really quickly to.

222
00:26:06.230 --> 00:26:07.280
savrdce@auburn.edu: be yes.

223
00:26:08.150 --> 00:26:13.700
savrdce@auburn.edu: And so I think there's enough evidence from the literature of modern shrimpton.

224
00:26:15.980 --> 00:26:22.250
savrdce@auburn.edu: The other side of that story, I should point out is that you know people have modeled the progress.

225
00:26:23.120 --> 00:26:31.940
savrdce@auburn.edu: Of the waves and it wasn't one big mega wave we had these waves oscillating back and forth across the proto Gulf of Mexico.

226
00:26:32.810 --> 00:26:54.110
savrdce@auburn.edu: And I think they indicated that the period one modeling paper that the period would be a bait about eight hours and so maybe there were periods of relative qui essence in between waves that these locks on a set that's what they are these pioneers.

227
00:26:55.490 --> 00:27:02.150
savrdce@auburn.edu: would have maybe an hour or a few hours to actually do the work we seem manifest those The lesson.

228
00:27:04.460 --> 00:27:14.510
Rindsberg, Andrew: Well, I don't think I don't I think this is that was the least plausible part of your your field trip but.

229
00:27:17.000 --> 00:27:18.380
Rindsberg, Andrew: Obviously the birds are there.

230
00:27:19.640 --> 00:27:28.970
Rindsberg, Andrew: An alternative hypothesis might be that they there aren't very many visible vertical shafts and that they are actually.

231
00:27:30.230 --> 00:27:40.730
Rindsberg, Andrew: They conquer and they preferred particular layers within the sand, for some reason, and we know that animals, sometimes do that it would all be it would still be peculiar because.

232
00:27:41.750 --> 00:27:46.850
Rindsberg, Andrew: they're like three basic layers and they have different segments illogical styles.

233
00:27:47.960 --> 00:27:48.830
Rindsberg, Andrew: As you've noticed.

234
00:27:49.850 --> 00:27:50.900
Rindsberg, Andrew: What i'd like to know is.

235
00:27:52.250 --> 00:27:59.690
Rindsberg, Andrew: The one at least the ones toward the top are filled with chalk, so I presume that if micro micro paleontologist.

236
00:28:01.460 --> 00:28:08.840
Rindsberg, Andrew: took scrapings from that they find clayton age material i'd like to know about the lower ones, though.

237
00:28:09.350 --> 00:28:10.670
Rindsberg, Andrew: Right so.

238
00:28:10.730 --> 00:28:11.570
Rindsberg, Andrew: that's festival.

239
00:28:12.050 --> 00:28:24.230
savrdce@auburn.edu: yeah and that's one of the things that I sorta was alluding to in terms of suggestions toward the end of the of the field trip but what's interesting is in both same body one in six.

240
00:28:25.580 --> 00:28:35.810
savrdce@auburn.edu: The same body six only has the one clearly defined layer and then that's I think equivalent to the upper layer at Sam body one.

241
00:28:37.400 --> 00:28:47.900
savrdce@auburn.edu: You have the penetrating across from the base of the clayton you have planar laminated sandstone that doesn't appear to be disrupted at all.

242
00:28:48.380 --> 00:28:57.860
savrdce@auburn.edu: And then you have an interval that's got more of a marley matrix and then you're back into parallel emanated sans that have the borough.

243
00:28:58.640 --> 00:29:07.520
savrdce@auburn.edu: And so it's my impression that the source horizon may actually be coming out of one of those Marty earlier intervals, which might suggest that.

244
00:29:07.880 --> 00:29:16.700
savrdce@auburn.edu: A little bit of a I don't want to say slack water but qui essence, where we had more time to maybe settle out some of the MIC right that got put into suspension.

245
00:29:17.870 --> 00:29:31.460
savrdce@auburn.edu: Excuse me if, in fact, that was related to to the mega waves, but I agonized in both of those same bodies, whether those were discrete buyer debated horizons and I hope we can get out there.

246
00:29:33.260 --> 00:29:35.810
savrdce@auburn.edu: And look at them together and.

247
00:29:36.080 --> 00:29:36.890
Rindsberg, Andrew: I would be nice.

248
00:29:38.480 --> 00:29:47.930
savrdce@auburn.edu: Because I argued with myself, you know, often and had to convince myself that those were discrete internal buyer debater horizons and.

249
00:29:49.130 --> 00:30:07.070
Rindsberg, Andrew: i've been well looking at your your slides I was planning to just delve into my memory of trying to remember what the field relations were, and it would be so easy to point to it and try to figure it out on on the outcrop yeah.

250
00:30:08.330 --> 00:30:08.810
Rindsberg, Andrew: But they.

251
00:30:09.860 --> 00:30:10.250
Rindsberg, Andrew: See.

252
00:30:11.270 --> 00:30:17.540
Rindsberg, Andrew: Have you taken then sections of the clayton sandstone I know it's pretty friable stuff.

253
00:30:18.230 --> 00:30:24.080
savrdce@auburn.edu: Like we have a we have a few things sections through upward through one of the.

254
00:30:25.460 --> 00:30:28.040
savrdce@auburn.edu: sand bodies now I can't remember which number.

255
00:30:29.150 --> 00:30:34.640
savrdce@auburn.edu: And those samples were taken fairly early before we were actually numbering them.

256
00:30:36.290 --> 00:30:45.410
savrdce@auburn.edu: But they do vary texturally and they also vary significantly, I think the ones in the lower part primarily contain a.

257
00:30:47.180 --> 00:31:03.830
savrdce@auburn.edu: particular topic carbonate cements and then some of the other intervals, are more blocky or, in some cases it's a MIC right matrix summit, so the matrix the green size in the matrix do very.

258
00:31:05.300 --> 00:31:14.450
savrdce@auburn.edu: Through through the units one of the things that I think would be interesting, we we didn't do this is take a closer look at sediment technology, for example.

259
00:31:15.650 --> 00:31:21.410
savrdce@auburn.edu: same body one or any of the same bodies, I mean they're clearly deposition will units.

260
00:31:22.760 --> 00:31:28.820
savrdce@auburn.edu: And it would be interesting to see whether you can actually even though they're discreet Sam bodies, whether you could match up.

261
00:31:29.900 --> 00:31:36.950
savrdce@auburn.edu: texturally or fabric wise, because that would indicate that they're responding to the same.

262
00:31:38.060 --> 00:31:44.930
savrdce@auburn.edu: deposition process in these fault bounded depth of centers as opposed to oh you've got some near shore.

263
00:31:46.100 --> 00:31:48.110
savrdce@auburn.edu: sedimentation going on in these.

264
00:31:48.110 --> 00:31:49.160
savrdce@auburn.edu: flooded areas.

265
00:31:50.840 --> 00:31:52.670
savrdce@auburn.edu: And so I think that's something that.

266
00:31:53.780 --> 00:31:55.670
savrdce@auburn.edu: That that could be done.

267
00:31:56.810 --> 00:31:58.310
savrdce@auburn.edu: Look at a little bit more carefully.

268
00:31:59.300 --> 00:32:02.600
Rindsberg, Andrew: Another queue that I have is if.

269
00:32:04.130 --> 00:32:08.000
Rindsberg, Andrew: The bird is at the top of the co plane, or whatever, whatever you call it.

270
00:32:09.860 --> 00:32:21.470
Rindsberg, Andrew: they're doing much the same thing in the chalk, as they are in the sand and if the sound was loose, then why aren't they doing a few morphing the sand and the last night is in the chalk.

271
00:32:24.650 --> 00:32:25.010
savrdce@auburn.edu: that's.

272
00:32:25.130 --> 00:32:25.850
Rindsberg, Andrew: Why, why are they.

273
00:32:25.910 --> 00:32:29.450
Rindsberg, Andrew: Helping they're reinforcing their versus pay them.

274
00:32:30.200 --> 00:32:32.030
savrdce@auburn.edu: Well it's interesting question the.

275
00:32:33.830 --> 00:32:42.860
savrdce@auburn.edu: There they're clearly differences in overall morphology I think the ones where there's no clayton saying they tend to be more vertical.

276
00:32:45.590 --> 00:32:52.910
savrdce@auburn.edu: And so I would consider those things to represent firm grounds I don't see anything in the ones that are placed in the tops of the same bodies.

277
00:32:54.440 --> 00:33:03.110
savrdce@auburn.edu: It looks like they're just you know plain old the last annoyed ease and placed in a granular sand but getting back to your question is.

278
00:33:03.860 --> 00:33:23.720
savrdce@auburn.edu: If those things are being placed as the shore face migrates landward and the substrates they're being placed in aren't necessarily shifting and characterized by rapid erosion or rapid deposition maybe the crustaceans didn't need to tell it ties the other.

279
00:33:24.770 --> 00:33:29.630
savrdce@auburn.edu: potential problem is that most of the fields of those burrows have been washed out.

280
00:33:30.230 --> 00:33:32.240
savrdce@auburn.edu: yeah due to high water in the river.

281
00:33:32.660 --> 00:33:36.440
Rindsberg, Andrew: Yes, but you can see the chalk and then, if you look yeah for her.

282
00:33:38.360 --> 00:33:52.970
savrdce@auburn.edu: But, but I have one photograph that I took probably 15 years ago from Sam body six the one at the southern end where it actually so, and this would be in one of these lead internal.

283
00:33:53.510 --> 00:34:03.980
savrdce@auburn.edu: Fire debated horizons, there is one that has fluted engines that look for all the world like it was pelted in the pellets as well as the film were washed out.

284
00:34:05.450 --> 00:34:06.380
savrdce@auburn.edu: But it's only one.

285
00:34:07.520 --> 00:34:12.020
Rindsberg, Andrew: But this brings up another point I hadn't occurred to me until this moment.

286
00:34:13.850 --> 00:34:22.220
Rindsberg, Andrew: Okay you've got a mega wave has just brought in Washington sand and and shrimp the doomed pioneers.

287
00:34:23.750 --> 00:34:36.800
Rindsberg, Andrew: That sand is not fun, no, it does the shrimp couldn't this shrimp or as would have collapsed, but this was saying that had been deposited only hours before.

288
00:34:44.210 --> 00:34:45.320
savrdce@auburn.edu: I don't know why would.

289
00:34:46.910 --> 00:34:52.220
savrdce@auburn.edu: Why would they necessarily collapse, I mean we see a crust the shrimp burrows in.

290
00:34:53.510 --> 00:34:56.450
savrdce@auburn.edu: The last and he's in near shore sans.

291
00:34:56.930 --> 00:35:03.650
Rindsberg, Andrew: These would be sensitive been deposited only hours before it would be fixed Tropic it'd be very.

292
00:35:05.870 --> 00:35:06.320
Rindsberg, Andrew: wet.

293
00:35:09.080 --> 00:35:09.290
savrdce@auburn.edu: well.

294
00:35:09.770 --> 00:35:11.420
savrdce@auburn.edu: I don't know how fix a tropical.

295
00:35:11.570 --> 00:35:15.350
savrdce@auburn.edu: Be that's an interesting point, though, so.

296
00:35:17.210 --> 00:35:19.580
savrdce@auburn.edu: You just don't like my megaliths surfing.

297
00:35:22.850 --> 00:35:24.590
Rindsberg, Andrew: Just looked so normal.

298
00:35:26.060 --> 00:35:27.470
Rindsberg, Andrew: there's too much of them.

299
00:35:28.340 --> 00:35:39.740
Michael Thonis: The sand bodies or or maybe they're if they're fought fall down they might be drink me they may be an orientation to the overall were there, or just coincidentally on this site.

300
00:35:40.310 --> 00:35:56.030
Michael Thonis: The six or four on the site that were there drain where they drain or they may just be dipping the actual the actual fault Valley, the valley created by the faulty maybe just draining you know in some direction and drying fairly quickly.

301
00:35:56.450 --> 00:35:58.340
Rindsberg, Andrew: move would also be under the sea.

302
00:35:59.420 --> 00:35:59.870
Michael Thonis: yeah.

303
00:36:01.160 --> 00:36:01.550
savrdce@auburn.edu: resume.

304
00:36:02.000 --> 00:36:04.160
Michael Thonis: that's right yeah that's right see.

305
00:36:04.850 --> 00:36:18.020
savrdce@auburn.edu: One of the things I mean john Smith, who also interprets the wedge shapes and bodies as as related to mega wave deposition one of the things that he didn't consider.

306
00:36:20.150 --> 00:36:20.900
savrdce@auburn.edu: Is that.

307
00:36:22.310 --> 00:36:27.980
savrdce@auburn.edu: If they pray bluff clayton contact is a sequence boundary.

308
00:36:29.150 --> 00:36:35.090
savrdce@auburn.edu: And if there are no one size valley feels and it's a Co plane or transgressive sequence boundary.

309
00:36:36.260 --> 00:36:49.910
savrdce@auburn.edu: sea level had to a fall sometime before deposition of the clayton sand, and so the question is when the mega waves if assuming mega waves, the positive.

310
00:36:50.960 --> 00:36:53.060
savrdce@auburn.edu: All or parts of the same bodies.

311
00:36:54.110 --> 00:37:06.380
savrdce@auburn.edu: What was the sea level and i'm not saying that prairie bluff had to been severely exposed but sea level had to have fallen in the lake rotations.

312
00:37:09.140 --> 00:37:24.530
Michael Thonis: I was thinking sub Ariel exposed between the between the mega waves, because you know when there's a mega wave it the way it pulls all the water back away from away from the shoreline puts the shoreline way out.

313
00:37:26.090 --> 00:37:40.910
Michael Thonis: It just that's watching videos you know things like that Japan tsunami or the tsunami in the Indian Ocean, where it's just a huge amount of water just disappears goes out 30 miles and then come back with a vengeance.

314
00:37:41.660 --> 00:37:42.740
Rindsberg, Andrew: I don't know we know how.

315
00:37:43.490 --> 00:37:43.850
hard.

316
00:37:45.110 --> 00:37:49.550
Rindsberg, Andrew: i'm sorry I don't think anyone knows truly how high the wave was.

317
00:37:49.610 --> 00:37:53.390
Michael Thonis: No right right i'm just thinking about several possibility and.

318
00:37:54.590 --> 00:38:01.850
Michael Thonis: These these and these shrimp are scrambling to get down to you know below the water table locally.

319
00:38:02.870 --> 00:38:09.650
Michael Thonis: And you've got eight hours to do it, and I know is that I don't know enough about this topic, but does that who knows right.

320
00:38:11.690 --> 00:38:12.890
Rindsberg, Andrew: Not a geophysicist.

321
00:38:15.980 --> 00:38:16.460
savrdce@auburn.edu: Things.

322
00:38:16.640 --> 00:38:19.490
savrdce@auburn.edu: do with it, when the argument became Okay, are these.

323
00:38:20.810 --> 00:38:34.340
savrdce@auburn.edu: mega wave deposits or they thin little in size valley feels I mean insides me how he feels let's say in the western interior, where you had greater substance and more accommodation space they're up to 10s if not hundreds of meters.

324
00:38:36.080 --> 00:38:40.400
savrdce@auburn.edu: The sand bodies are probably no more than two meters stick, but if you.

325
00:38:41.870 --> 00:38:49.100
savrdce@auburn.edu: How do you get an inside Valley, to you, you have sea level fall subfertile exposure and erosion.

326
00:38:50.300 --> 00:38:53.600
savrdce@auburn.edu: And then during the initial transgression.

327
00:38:54.650 --> 00:39:04.700
savrdce@auburn.edu: As base levels rise you fill in those depressions and then the short face comes through well now let's take a mega wave.

328
00:39:06.800 --> 00:39:12.800
savrdce@auburn.edu: The trough of the mega wave hits first so you have withdrawal of the sea.

329
00:39:14.060 --> 00:39:16.100
savrdce@auburn.edu: And then, as the.

330
00:39:18.050 --> 00:39:21.800
savrdce@auburn.edu: The first mega wave comes running through.

331
00:39:23.090 --> 00:39:24.080
savrdce@auburn.edu: You could.

332
00:39:25.430 --> 00:39:30.740
savrdce@auburn.edu: conceivably feel these depressions in this case, they were produced by faulting if we said.

333
00:39:31.940 --> 00:39:33.860
savrdce@auburn.edu: Moscow landing and then.

334
00:39:34.910 --> 00:39:43.490
savrdce@auburn.edu: That erosion will surface at the top could potentially have something to do with the the mega which so to me it's like this the mega wave model could almost.

335
00:39:44.570 --> 00:39:47.900
savrdce@auburn.edu: be a sped up version of a sea levels.

336
00:39:48.830 --> 00:39:49.100
yeah.

337
00:39:50.330 --> 00:39:50.600
Rindsberg, Andrew: yeah.

338
00:39:51.140 --> 00:39:51.920
Rindsberg, Andrew: You could have.

339
00:39:54.050 --> 00:40:05.150
Rindsberg, Andrew: Okay you've got the Sheikh shalhoub impact that's going to generate the granddaddy of all earthquakes, so the faults are formed before the tsunamis hit several hours later.

340
00:40:07.010 --> 00:40:22.400
Michael Thonis: mm hmm yeah they're happening almost simultaneously with that well not simultaneously but pretty quickly after the event, I should I don't know that due to mega waves travel faster than seismic waves I think they travel more slowly, I think.

341
00:40:23.090 --> 00:40:24.980
Michael Thonis: Ours our slogan.

342
00:40:25.670 --> 00:40:33.230
Rindsberg, Andrew: She actually would have been what 900 miles south of here I think about 1000 miles.

343
00:40:35.660 --> 00:40:38.450
savrdce@auburn.edu: I wouldn't hazard a guess have to look at a map.

344
00:40:39.110 --> 00:40:42.380
Michael Thonis: I think that sounds right but you're in your in your geophysicist so you.

345
00:40:43.670 --> 00:40:44.600
Rindsberg, Andrew: said what you said earlier.

346
00:40:44.840 --> 00:40:45.890
Michael Thonis: So how fast would.

347
00:40:47.150 --> 00:40:58.460
Michael Thonis: plus or minus a few hundred miles, what would you know kilometers what would how fast does it take for the seismic the first seismic waves to arrive, not long right.

348
00:40:59.990 --> 00:41:01.460
Rindsberg, Andrew: Hours hours.

349
00:41:01.490 --> 00:41:04.700
Scott Brande: yeah well the the the propagation of.

350
00:41:06.200 --> 00:41:13.040
Scott Brande: Body waves and the crust is somewhere around call it, five, six kilometres per second and.

351
00:41:13.100 --> 00:41:15.590
Scott Brande: The segment of the tsunami waves.

352
00:41:16.040 --> 00:41:24.020
Scott Brande: are only about four to 450 miles an hour so as as Andy said it's it's a huge difference.

353
00:41:25.040 --> 00:41:30.500
Scott Brande: In the transmission time between the head of the seismic wave and the head of the the ocean wave.

354
00:41:31.130 --> 00:41:47.030
Michael Thonis: So the series of events could be the impact, then the huge mega earthquake, you know which breaks up at least the surface, and these are probably semi liquefied right materials right and.

355
00:41:48.260 --> 00:41:48.770
Michael Thonis: And then.

356
00:41:50.000 --> 00:41:56.900
Michael Thonis: And then the next event happens is that the way the water pulls out like a like a regression just pulls way out.

357
00:41:57.680 --> 00:42:11.300
Michael Thonis: And then, and then hours later comes back with a vengeance, and that probably repeats a few times meanwhile the shrimp you know they're like have no idea what's going on right, but all they know is that every time you get a chance, he just borrow down.

358
00:42:13.610 --> 00:42:13.940
Rindsberg, Andrew: well.

359
00:42:15.050 --> 00:42:16.190
Rindsberg, Andrew: there's your walk and get away.

360
00:42:16.280 --> 00:42:17.060
savrdce@auburn.edu: My theory.

361
00:42:20.060 --> 00:42:29.450
Rindsberg, Andrew: I like Superman additional evidence for you some things that you may not have been able to see because I had somewhat different experiences at the side.

362
00:42:30.680 --> 00:42:31.250
Rindsberg, Andrew: But that's.

363
00:42:32.360 --> 00:42:40.730
Rindsberg, Andrew: Instead of poking at your weak point let's i'm going to i'm going to strengthen your already strong point okay.

364
00:42:42.500 --> 00:42:53.570
Rindsberg, Andrew: bear with me i've got more than one point here one of them, the faults, I have more than once, gone down on a boat trip from demonic lists to Moscow landing.

365
00:42:55.190 --> 00:43:00.950
Rindsberg, Andrew: On the Tom baby river at the marvelous the faults are few and displacement is like.

366
00:43:01.610 --> 00:43:21.440
Rindsberg, Andrew: As you go farther South the displacement the faults become more numerous and the displacement displacement gets greater until you get to Moscow landing and virtually every KPMG site now Alabama I don't know about brags but as far as I know, all of the others are faulted.

367
00:43:24.380 --> 00:43:32.930
Rindsberg, Andrew: including some that are now permanently underwater destroyed by eugene Allen Smith in the in the 1800s I can't bluff.

368
00:43:34.190 --> 00:43:37.400
Rindsberg, Andrew: So this these folks are not local.

369
00:43:38.690 --> 00:43:45.530
Rindsberg, Andrew: This you can pretty much assume that the whole coastal plain of Alabama got faulted and I think simultaneously.

370
00:43:48.050 --> 00:43:56.060
Rindsberg, Andrew: Okay, so that's one strengthening piece of evidence, another is the caitlyn the cobbles of chalk.

371
00:43:58.130 --> 00:44:17.180
Rindsberg, Andrew: They are the wrong shape to be formed in local creeks and rivers i've been on many creeks and rivers and Alabama and if that child was anything like the chocolate today, maybe a little less less liquefied it should be shaped in slabs.

372
00:44:18.620 --> 00:44:32.540
Rindsberg, Andrew: They tend to get plucked up in the in the creeks and then moved if they're broken down much further they're not slabs anymore or or blocks or rectangular blocks that are often joint bound rounded.

373
00:44:34.250 --> 00:44:44.960
Rindsberg, Andrew: Rather than these very rounded looking cobbles that you see at Moscow landing, I simply don't believe that there's a river process that could produce that shape of chalk.

374
00:44:46.700 --> 00:44:51.080
Rindsberg, Andrew: So we've got something else, those that truck rolled.

375
00:44:52.370 --> 00:44:57.680
Rindsberg, Andrew: Okay, what we should be looking for is armory of these giant clay balls.

376
00:45:00.050 --> 00:45:10.820
Rindsberg, Andrew: Another feature that some of this chalk day breathe some of it quite course is actually injected down into these faults that Moscow landing.

377
00:45:12.650 --> 00:45:15.950
Rindsberg, Andrew: That means that those faults moved exactly once.

378
00:45:18.110 --> 00:45:21.710
Rindsberg, Andrew: and did not otherwise there's chalk cobbles would today be smeared.

379
00:45:24.560 --> 00:45:33.620
Rindsberg, Andrew: So yes, some of the faults did continue to move in the paleocene I think that's clear, but some of them moved once.

380
00:45:35.240 --> 00:45:36.680
Rindsberg, Andrew: During a disaster.

381
00:45:38.480 --> 00:45:42.020
Scott Brande: And a with regard to those boulders if you will.

382
00:45:43.190 --> 00:45:49.310
Scott Brande: Is there any petrol graphic analysis of the.

383
00:45:50.630 --> 00:45:52.580
Scott Brande: interior of those.

384
00:45:56.960 --> 00:45:58.460
Scott Brande: is just a partners or cobbles.

385
00:45:58.700 --> 00:46:02.030
Scott Brande: versus verte couples versus.

386
00:46:03.110 --> 00:46:08.360
Scott Brande: The matrix which would be within a couple of centimeters outside I mean i'm i'm trying to picture.

387
00:46:10.370 --> 00:46:11.690
Scott Brande: The degree to which.

388
00:46:12.800 --> 00:46:15.170
Scott Brande: The chalk held together.

389
00:46:16.580 --> 00:46:17.570
Scott Brande: In a.

390
00:46:19.010 --> 00:46:20.540
Scott Brande: In a mechanical way.

391
00:46:21.620 --> 00:46:24.800
Scott Brande: As different from the surrounding matrix.

392
00:46:25.400 --> 00:46:32.030
Rindsberg, Andrew: I certainly haven't done any such studies Oh, there was one other thing to notice that was john smith's.

393
00:46:33.350 --> 00:46:36.800
Rindsberg, Andrew: Observation he he found and i'm.

394
00:46:37.880 --> 00:46:54.020
Rindsberg, Andrew: jack has confirmed that there were three main pebble to cut cobbled two double beds there, they are finding upwards, each one it's as if there was a way there's another wave and he had a third wave, how many more ways we don't know.

395
00:46:56.660 --> 00:46:58.820
Rindsberg, Andrew: But as far as cryptography goes.

396
00:46:59.870 --> 00:47:01.130
Rindsberg, Andrew: it's an open field.

397
00:47:02.240 --> 00:47:09.530
savrdce@auburn.edu: And it's interesting too, because in some of those wedge shaped bodies it's clear that there was a fault scarf.

398
00:47:10.550 --> 00:47:31.850
savrdce@auburn.edu: And those class were more or less being check that probably coming over the top, but those the work and glamour attic intervals, then, can shout generally to the north, depending what Sam body are looking looking at so they're probably all sorts of other things that could be.

399
00:47:33.020 --> 00:47:34.880
savrdce@auburn.edu: done to try to fill in.

400
00:47:37.190 --> 00:47:37.430
savrdce@auburn.edu: In.

401
00:47:40.580 --> 00:47:41.300
Rindsberg, Andrew: This important.

402
00:47:42.710 --> 00:47:47.000
Rindsberg, Andrew: there's there's not another outcrop it's so expensive that shows all these features.

403
00:47:50.270 --> 00:47:54.140
Sharon Browning: For saving, I want to get out to Moscow landing again anytime this year.

404
00:47:56.750 --> 00:47:57.350
savrdce@auburn.edu: Maybe.

405
00:48:00.140 --> 00:48:03.650
savrdce@auburn.edu: I haven't been out there now and and probably over a year.

406
00:48:05.690 --> 00:48:06.350
savrdce@auburn.edu: Colvin.

407
00:48:07.400 --> 00:48:13.820
savrdce@auburn.edu: And the property situation kind of hit I was under the impression that the.

408
00:48:15.170 --> 00:48:24.380
savrdce@auburn.edu: And Andy clarified this at the beginning of our session but I had the misunderstanding that property lines or high water.

409
00:48:25.220 --> 00:48:39.350
savrdce@auburn.edu: mark and also there is a the gas pipeline that goes through the River there's a an access for utility and thinking that that was also public right away, and as Andy described before.

410
00:48:40.940 --> 00:48:42.950
savrdce@auburn.edu: I was wrong, it had been trespass.

411
00:48:46.670 --> 00:48:52.220
savrdce@auburn.edu: And so I think if we make the right connections Andy has already started and.

412
00:48:54.410 --> 00:48:56.660
savrdce@auburn.edu: I may try to introduce myself and.

413
00:48:58.040 --> 00:48:59.390
savrdce@auburn.edu: Give them a glossy.

414
00:49:00.470 --> 00:49:09.440
savrdce@auburn.edu: balloon up map strip napa there shoreline maybe that would use a dad of the call the COPs and say how did you do this with that trespassing them I.

415
00:49:10.970 --> 00:49:12.650
Michael Thonis: don't have the sweet occupies of that one.

416
00:49:13.100 --> 00:49:19.790
Rindsberg, Andrew: Well, I when I talked to him, like, I had a field trip and co and he said, what are you doing here.

417
00:49:21.980 --> 00:49:26.840
Rindsberg, Andrew: There I was at the bridge and we had quite a discussion I he left he, let us go.

418
00:49:29.690 --> 00:49:42.350
Rindsberg, Andrew: But I think mostly it was his honor that was being that he was thinking about he does, I don't think he really cares about all these field trips, as long as people ask for permission ahead time.

419
00:49:43.010 --> 00:49:52.280
Michael Thonis: Was, you know as long as you know, find a whole a whole tire and osiris fossil you know in there because that's that's out West right wyoming in.

420
00:49:53.300 --> 00:49:55.250
Rindsberg, Andrew: The code and that would be the kiss of death.

421
00:49:55.430 --> 00:49:56.240
Michael Thonis: yeah nobody.

422
00:49:56.570 --> 00:50:02.150
Michael Thonis: will know rancher will it just doesn't happen anymore, they will not give you access on the properties.

423
00:50:02.810 --> 00:50:06.440
Sharon Browning: But I wonder to about a liability issue because, if I remember that.

424
00:50:06.500 --> 00:50:09.260
Sharon Browning: Ben riverbank can be pretty slippery.

425
00:50:09.260 --> 00:50:11.270
Rindsberg, Andrew: Sometimes, yes yeah he was.

426
00:50:11.330 --> 00:50:12.470
Rindsberg, Andrew: He was concerned about.

427
00:50:13.130 --> 00:50:16.490
Rindsberg, Andrew: I wrote a handwritten liability waiver and.

428
00:50:16.490 --> 00:50:18.410
Rindsberg, Andrew: Had everyone sign it on the spot.

429
00:50:19.370 --> 00:50:20.360
Yes, that better.

430
00:50:21.740 --> 00:50:23.930
Michael Thonis: picture, do you have a do you have a.

431
00:50:24.980 --> 00:50:33.320
Michael Thonis: Full a composite of photographs of the I can't remember I don't think I saw that in the video of your strip map, but you have.

432
00:50:35.330 --> 00:50:37.610
Michael Thonis: Like you know what I mean a panorama.

433
00:50:39.290 --> 00:50:39.800
savrdce@auburn.edu: know.

434
00:50:41.420 --> 00:50:45.320
savrdce@auburn.edu: When I first started working out their digital cameras or.

435
00:50:45.950 --> 00:50:47.000
Michael Thonis: yeah yeah.

436
00:50:47.330 --> 00:50:56.510
savrdce@auburn.edu: And in order to try to sketch what we were seeing we dragged a canoe down there and I took an old polaroid camera.

437
00:50:58.250 --> 00:51:08.120
savrdce@auburn.edu: And as we floated down the river right, and so, and then what we did was put overlays on that sketched it so that the geometry is a little distorted but.

438
00:51:11.900 --> 00:51:15.380
savrdce@auburn.edu: We have some cross sectional view sketches that we've done but.

439
00:51:16.460 --> 00:51:19.880
savrdce@auburn.edu: It would have been neat to do a you know, to get a drone out there.

440
00:51:20.240 --> 00:51:25.940
Michael Thonis: Well, I was just thinking about my museum of science, you know how that would make a great Ural.

441
00:51:27.440 --> 00:51:34.370
Michael Thonis: In health people understand get us, you know it, you know, point out that we don't know sure what happened, but one possibility is.

442
00:51:35.450 --> 00:51:45.980
Michael Thonis: As supported, partly by this panorama this mural is the following story which I just think it's kind of you know you always wanting to museum to be as scintillating as possible yeah.

443
00:51:46.070 --> 00:51:58.850
savrdce@auburn.edu: Well, given the scale and the length of minutes, one point Gomez two kilometers long and and the outcrops Andy what maximum five meters in any one place if you.

444
00:51:59.090 --> 00:52:01.910
savrdce@auburn.edu: Had a whole panorama you wouldn't be able to see.

445
00:52:02.330 --> 00:52:09.950
Michael Thonis: No, but you know what these digital which you can do with these digital photos, as you can change the scales, you know, however, often the trial set.

446
00:52:09.950 --> 00:52:10.580
savrdce@auburn.edu: stretch it out.

447
00:52:10.880 --> 00:52:13.700
Michael Thonis: Well, you know the Cross section, you might have you know five X.

448
00:52:14.000 --> 00:52:14.240
savrdce@auburn.edu: yeah.

449
00:52:14.360 --> 00:52:20.030
Michael Thonis: On the vertical you can do that, you can actually do that with a with you know by digitizing it.

450
00:52:21.500 --> 00:52:31.070
Michael Thonis: And i've seen actually were there's a name for it, but the you can take separate photos and then using software stitch them together like you're just one.

451
00:52:32.330 --> 00:52:39.800
Michael Thonis: Like one large panoramic photo it's got huge detail, you know the pixels are terrific.

452
00:52:40.490 --> 00:52:42.440
Sharon Browning: Are you talking about like a giga pan.

453
00:52:42.590 --> 00:52:46.760
Michael Thonis: yeah good Japan that's it, thank you, the giga pan yeah that that technology.

454
00:52:46.850 --> 00:52:47.540
Van Burbach: i'm gonna have to.

455
00:52:48.950 --> 00:52:49.310
Michael Thonis: deal.

456
00:52:49.460 --> 00:52:49.910
With thanks.

457
00:52:53.750 --> 00:52:59.660
Michael Thonis: So that would you know you can really grateful i'm just i'm just thinking of maybe maybe i'll make contact you at some point.

458
00:53:00.770 --> 00:53:03.740
Michael Thonis: and go on a field trip with you and we'll get all the right permissions.

459
00:53:05.690 --> 00:53:06.980
Rindsberg, Andrew: That would be so wonder.

460
00:53:08.300 --> 00:53:09.710
Rindsberg, Andrew: It should be done on a.

461
00:53:10.790 --> 00:53:12.950
Rindsberg, Andrew: On a day when the river is flat so.

462
00:53:14.810 --> 00:53:15.200
Michael Thonis: Low.

463
00:53:15.260 --> 00:53:18.860
Rindsberg, Andrew: The drones you're right with drones you wouldn't matter with it.

464
00:53:20.270 --> 00:53:20.570
Rindsberg, Andrew: wow.

465
00:53:21.920 --> 00:53:28.490
savrdce@auburn.edu: Well, I think it'd be hard to settle the issue of the mega wave surfing shrimp using a drone I think.

466
00:53:29.180 --> 00:53:30.740
savrdce@auburn.edu: We need to get our nose right on.

467
00:53:30.740 --> 00:53:31.130
savrdce@auburn.edu: The good.

468
00:53:33.050 --> 00:53:49.520
Scott Brande: hey chuck i'm going to have to go shortly, but I just wanted to bring back, maybe a memory that I have held strongly since 1996 and specifically in May and you might You might remember whoops, how can I do this.

469
00:53:50.750 --> 00:53:51.830
Sharon Browning: Virtual background.

470
00:53:52.400 --> 00:53:55.400
Scott Brande: Yes, buddy oh there it is.

471
00:53:55.460 --> 00:53:57.080
Michael Thonis: Okay dad dinosaurs.

472
00:53:57.260 --> 00:54:10.190
Scott Brande: dead dead dead dinosaurs right, and this is when yeah i'll see if I can get this this is when Walter Alvarez came to Alabama for his one.

473
00:54:11.930 --> 00:54:21.230
Scott Brande: Guided field trip with you, and what I did is since a friend of mine was writing for the burnham news Jeff handsome.

474
00:54:22.130 --> 00:54:38.180
Scott Brande: came along on the trip and I brought to Birmingham City school teachers and so we had a wonderful time with you as you were leading one of your your local field trips down there may may of 1996.

475
00:54:39.260 --> 00:54:42.560
Scott Brande: And and Alvarez apparently enjoyed it greatly at that time.

476
00:54:45.980 --> 00:54:47.810
savrdce@auburn.edu: Are you are you talking to Andy.

477
00:54:48.440 --> 00:54:49.160
Scott Brande: No i'm talking.

478
00:54:49.250 --> 00:54:50.990
Scott Brande: i'm talking to you chuck.

479
00:54:51.470 --> 00:54:57.890
savrdce@auburn.edu: Oh well, i'll take credit for, but I think I would Alvarez, on a future down there so.

480
00:54:58.280 --> 00:54:59.330
Scott Brande: yeah well.

481
00:55:01.220 --> 00:55:01.610
Scott Brande: well.

482
00:55:03.080 --> 00:55:03.920
Sharon Browning: shoemaker.

483
00:55:04.550 --> 00:55:05.180
Scott Brande: It definitely.

484
00:55:05.570 --> 00:55:06.290
Rindsberg, Andrew: wasn't me.

485
00:55:07.610 --> 00:55:08.000
Michael Thonis: well.

486
00:55:09.560 --> 00:55:12.110
savrdce@auburn.edu: crowded Charlie Charlie Smith navy.

487
00:55:13.820 --> 00:55:16.580
Scott Brande: Was Charlie the one who argued against.

488
00:55:17.690 --> 00:55:18.560
Rindsberg, Andrew: Yes.

489
00:55:18.620 --> 00:55:21.350
Rindsberg, Andrew: Yes, and he's he's a nano expert.

490
00:55:22.460 --> 00:55:27.320
Rindsberg, Andrew: I don't know what he's doing now, but he says that eventually he wants his ashes, to be spread at Moscow.

491
00:55:28.850 --> 00:55:30.290
Scott Brande: Oh good Lord.

492
00:55:32.330 --> 00:55:32.720
Scott Brande: well.

493
00:55:33.770 --> 00:55:41.330
Scott Brande: In any case, i've got the head off, but thanks for the incredible graphics and the photographs as well chuck so I really appreciate it.

494
00:55:41.540 --> 00:55:44.060
Michael Thonis: Thanks, thank you, thank you chuck i'm gonna go to thank you.

495
00:55:44.300 --> 00:55:44.870
savrdce@auburn.edu: Mike Thank you.

496
00:55:48.500 --> 00:55:48.950
Rindsberg, Andrew: well.

497
00:55:56.510 --> 00:56:15.050
Sharon Browning: But preserving, it is an issue because I remember seeing the ups site just off of air base boulevard and and that's gone now because it took that CAP rock for the zoo and that meat or scale cross stratification that was preserved there yeah I think it was the utah formation.

498
00:56:16.040 --> 00:56:17.600
savrdce@auburn.edu: yeah the topic be saying.

499
00:56:17.870 --> 00:56:20.570
Rindsberg, Andrew: Suddenly, so the River outcrops are.

500
00:56:20.600 --> 00:56:30.380
Rindsberg, Andrew: Self renewing in a way, I mean it's a subtracted process, the fact is, you can go there many times and see something different, every time you go.

501
00:56:30.620 --> 00:56:30.950
Oh, you.

502
00:56:33.740 --> 00:56:34.490
savrdce@auburn.edu: know the.

503
00:56:36.020 --> 00:56:48.560
savrdce@auburn.edu: you're talking about preservation, I thought, what this may be a harebrained idea and Andy I think you were highly involved in the what is the Union Chapel mind is that the right.

504
00:56:50.330 --> 00:56:51.230
Rindsberg, Andrew: One time yes.

505
00:56:51.410 --> 00:56:54.200
savrdce@auburn.edu: yeah in terms of getting that preserved.

506
00:56:55.340 --> 00:56:57.260
savrdce@auburn.edu: Is that state property now right.

507
00:56:58.250 --> 00:56:59.270
Rindsberg, Andrew: It is.

508
00:56:59.870 --> 00:57:08.390
savrdce@auburn.edu: i'm just wondering whether we could figure out a way of preserving a strip of the Moscow landing section.

509
00:57:11.180 --> 00:57:12.920
savrdce@auburn.edu: Through a similar type of effort.

510
00:57:15.830 --> 00:57:19.100
Rindsberg, Andrew: It would be very different the Union Chapel mine was.

511
00:57:20.090 --> 00:57:21.440
Rindsberg, Andrew: A whole line of being shot.

512
00:57:21.440 --> 00:57:24.350
Rindsberg, Andrew: down, so the.

513
00:57:26.900 --> 00:57:35.780
Rindsberg, Andrew: Congress had to had to interfere, because it was because there was a federal law sayings inactive minds, have to be covered over again.

514
00:57:37.220 --> 00:57:45.020
Rindsberg, Andrew: So they had to make an exception, we got support from at her fault, one of our State Representatives.

515
00:57:48.050 --> 00:57:51.800
Rindsberg, Andrew: This and it was private property, and then I.

516
00:57:53.060 --> 00:58:02.660
Rindsberg, Andrew: I don't know how much money the other owners were given that they got something from the state I don't know how we've managed to do this in this.

517
00:58:02.690 --> 00:58:06.530
savrdce@auburn.edu: Is yeah I thought there was some sort of fundraising effort that actually.

518
00:58:06.530 --> 00:58:07.970
Rindsberg, Andrew: got better was.

519
00:58:08.330 --> 00:58:16.010
savrdce@auburn.edu: It to some degree, this could potentially be simpler, because you don't have the coal mining regulation.

520
00:58:18.020 --> 00:58:26.780
savrdce@auburn.edu: And it's kind of like you know just up to the edge of the woods, what are they going to do at that those nicely exposed products.

521
00:58:27.860 --> 00:58:42.620
savrdce@auburn.edu: And then they wouldn't have to worry about liability and it could be, it could be administered similar to the way the Herald station, or something like that is where it's through University of Alabama or something like that so.

522
00:58:45.860 --> 00:58:50.450
savrdce@auburn.edu: So there is some control on accessed but.

523
00:58:51.920 --> 00:59:00.410
savrdce@auburn.edu: And there be some sort of central clearing house or something that that let people in or gotten lucky or whatever, but.

524
00:59:02.900 --> 00:59:09.680
Rindsberg, Andrew: You who operates as a sumter county nature trust on.

525
00:59:10.700 --> 00:59:12.920
Rindsberg, Andrew: And through that they operate.

526
00:59:14.630 --> 00:59:35.000
Rindsberg, Andrew: A site on the River on an old bluff part it actually includes the type locality of the bluff part our own, although that was not their intention it's an archaeological site and it includes the laughs along the river, I could look into that and see how that was done.

527
00:59:36.470 --> 00:59:39.260
Rindsberg, Andrew: And that would be one avenue you.

528
00:59:41.300 --> 00:59:42.740
Rindsberg, Andrew: could also see that we could.

529
00:59:43.910 --> 00:59:45.710
Rindsberg, Andrew: go through the nature conservancy.

530
00:59:47.270 --> 00:59:54.680
Rindsberg, Andrew: which has a huge amount of experience in talking with landowners and soothing their ruffled feathers and.

531
00:59:56.030 --> 01:00:02.870
Rindsberg, Andrew: And sometimes leaving land in their hands, but within a kind of an easement.

532
01:00:04.400 --> 01:00:04.760
Rindsberg, Andrew: That.

533
01:00:06.470 --> 01:00:09.620
Rindsberg, Andrew: restrict certain kind of usage they do this with.

534
01:00:11.000 --> 01:00:14.420
Rindsberg, Andrew: Oh endangered plants, for instance.

535
01:00:15.530 --> 01:00:21.380
Rindsberg, Andrew: so that you know they might have an easement on a field and say you can hunt there all you like just just don't.

536
01:00:22.430 --> 01:00:24.440
Rindsberg, Andrew: Just don't plow it and use it for crops, you know.

537
01:00:25.250 --> 01:00:32.330
savrdce@auburn.edu: I guess if I was the property owner, I think that my biggest issue is one that Sharon mentioned was is the liability.

538
01:00:34.220 --> 01:00:42.320
savrdce@auburn.edu: And so you know you you filled out those had students sign it, but you know i've been told by lawyers that you know.

539
01:00:43.340 --> 01:00:47.660
savrdce@auburn.edu: Laughter have some that may not be worth the paper they're written on.

540
01:00:48.560 --> 01:00:49.520
Rindsberg, Andrew: Why do we have them.

541
01:00:50.390 --> 01:00:52.760
savrdce@auburn.edu: Question just to make us feel better.

542
01:00:55.460 --> 01:00:56.600
savrdce@auburn.edu: My understanding is.

543
01:00:57.050 --> 01:00:58.070
Sharon Browning: due diligence.

544
01:00:59.180 --> 01:01:05.960
savrdce@auburn.edu: My understanding is and I got a contact Nick to our state geologist who was the one that.

545
01:01:06.980 --> 01:01:15.440
savrdce@auburn.edu: Supposedly it's been communicating with the property owner, in the meantime early on, when I found out about the issue of access.

546
01:01:16.130 --> 01:01:35.450
savrdce@auburn.edu: I had a draft our people here are legal folks put together a draft and that might be something that I need to show the property owner to see whether that would suffice, but I know they've been communicating with the lawyers themselves about the liability issue and so.

547
01:01:36.680 --> 01:01:38.420
savrdce@auburn.edu: they're they're not just.

548
01:01:39.800 --> 01:01:46.430
savrdce@auburn.edu: now know off the cuff well we're concerned somebody might get hurt they're communicating bleak with legal counsel about it.

549
01:01:47.720 --> 01:02:04.010
Sharon Browning: Well, one other completely different topic question here, and then I have to go, do you see that I could see this easily being used for for undergraduates have you have you thought about I think I think this field trip is supposed to be made available on GSA website.

550
01:02:05.690 --> 01:02:06.560
Sharon Browning: Is that correct.

551
01:02:08.450 --> 01:02:10.700
savrdce@auburn.edu: audrey I don't know whether she's still listening.

552
01:02:11.630 --> 01:02:13.910
savrdce@auburn.edu: We were, I was asking about that, before.

553
01:02:14.810 --> 01:02:21.980
savrdce@auburn.edu: Apparently, this will remain in what archive for a year, so that anybody.

554
01:02:23.690 --> 01:02:31.580
savrdce@auburn.edu: Who registered already can go back and access, it is that correct or somebody could register for the meeting.

555
01:02:32.600 --> 01:02:40.310
savrdce@auburn.edu: Post meeting and access whatever recordings obsessions and field trips is that accurate.

556
01:02:40.640 --> 01:02:48.980
RISE GSA Audrey Heun: yep so so like anything on the meeting that we've recorded is going to be available for up to a year and then.

557
01:02:50.180 --> 01:02:57.830
RISE GSA Audrey Heun: you're since it was a pre recorded field trip we're actually going to archive that on the GSA website behind a member of a member wall.

558
01:02:59.510 --> 01:03:09.350
RISE GSA Audrey Heun: for however long i'm not quite sure, since this is a new process for GSA we're still trying to figure out kind of that process so.

559
01:03:10.220 --> 01:03:19.580
RISE GSA Audrey Heun: I think there's for field trips from the southeast meeting that agreed to have it archives we're still trying to figure out exactly what that looks like and what does that mean.

560
01:03:20.330 --> 01:03:29.510
savrdce@auburn.edu: You know, one of the things early on, when I was trying to design a trip, I was trying to break it into segments where you would show part of it, and then say okay students.

561
01:03:30.170 --> 01:03:39.080
savrdce@auburn.edu: What did you just hear draw cross section and using strategy graphic principal sequence of events, try to figure out what's going on.

562
01:03:40.310 --> 01:03:59.810
savrdce@auburn.edu: But I think you still could introduce things the basic things like strata graphic principles and that sort of thing using polar parts of the trip, so if it's archived as long as somebody's a member, even though they weren't registered for the meeting, they would be able to access.

563
01:04:01.850 --> 01:04:02.480
savrdce@auburn.edu: At least for.

564
01:04:03.350 --> 01:04:11.780
Sharon Browning: myself thinking and in a way, I never imagined we've developed all this online content for our students and.

565
01:04:12.890 --> 01:04:18.860
Sharon Browning: And some of it is is really good and I don't see getting rid of it, especially for field experiences.

566
01:04:23.180 --> 01:04:23.990
Sharon Browning: Okay, I have.

567
01:04:24.020 --> 01:04:40.820
RISE GSA Audrey Heun: Yet and there's even then talk just you know kind of going forward with field trips, should we be sending professional photographers or videographers out there and really capturing everything that's a lot more money, but that is kind of the talk of like.

568
01:04:41.150 --> 01:04:41.540
RISE GSA Audrey Heun: Is this.

569
01:04:41.660 --> 01:04:49.910
RISE GSA Audrey Heun: Where are we going like what we you know covert hit we're dealing with it, how can we kind of continue to maybe.

570
01:04:50.930 --> 01:04:51.800
RISE GSA Audrey Heun: make things better.

571
01:04:53.840 --> 01:04:54.860
Sharon Browning: Thank you very much.

572
01:04:55.010 --> 01:04:55.340
savrdce@auburn.edu: No.

573
01:04:56.300 --> 01:04:58.160
Rindsberg, Andrew: Thank you, sharing, that was a great question.

574
01:05:01.880 --> 01:05:18.080
Rindsberg, Andrew: Well, you know discovering Alabama does have does does send out professionals into the field to do just very similarly thanks, but they're not doing it it's such a technical level, as you are checking.

575
01:05:20.450 --> 01:05:22.670
Rindsberg, Andrew: So I think would be that would be wonderful if you could.

576
01:05:22.760 --> 01:05:26.450
Rindsberg, Andrew: If you could get in touch with them with discovering Alabama Doug Phillips.

577
01:05:26.690 --> 01:05:35.870
savrdce@auburn.edu: yeah I can do with Doug Phillips, and took the sands of time, the mighty Tom big me river here flows southward across the coastal plain.

578
01:05:39.590 --> 01:05:43.010
Rindsberg, Andrew: Until it flowed backward and the great tsunami yeah.

579
01:05:43.910 --> 01:05:46.310
savrdce@auburn.edu: Maybe that's the voice, I should have done the field trip.

580
01:05:47.300 --> 01:05:49.310
RISE GSA Audrey Heun: To say where's the British British accent.

581
01:05:50.780 --> 01:05:52.610
Rindsberg, Andrew: What will know that you're doing.

582
01:05:52.640 --> 01:05:58.160
Rindsberg, Andrew: Real detailed work chuck when you tell us what season of the year, it happened in.

583
01:06:00.650 --> 01:06:06.530
Rindsberg, Andrew: i'll bet you can do it with if you look careful attention to the oyster growth lines.

584
01:06:19.940 --> 01:06:23.000
Rindsberg, Andrew: Actually, until I said it, I hadn't realized, it is actually possible.

585
01:06:26.810 --> 01:06:29.000
Rindsberg, Andrew: Well, that would make a great article in nature.

586
01:06:30.080 --> 01:06:34.460
savrdce@auburn.edu: Yes, yes, you draft it up send it to me and i'll add my part.

587
01:06:39.170 --> 01:06:47.030
savrdce@auburn.edu: Right any any other questions comments I think we've we've gone over and I don't know what time is the closing remarks that bill haynes's.

588
01:06:49.370 --> 01:06:57.020
RISE GSA Audrey Heun: I have to arrive at 425 mountain time, I think it starts at 545 central time okay.

589
01:06:59.870 --> 01:07:02.840
savrdce@auburn.edu: Any other questions comments so Terry john.

590
01:07:04.190 --> 01:07:04.730
savrdce@auburn.edu: So.

591
01:07:07.070 --> 01:07:10.370
John Fronimos: chuck I didn't have a lot of insights not being a.

592
01:07:11.990 --> 01:07:14.420
John Fronimos: You know somebody who does a lot with trace fossils but I did have.

593
01:07:15.260 --> 01:07:21.770
John Fronimos: One question I imagine you probably would have mentioned it if you'd seen something like this, when you talk about the you know the surfing shrimps and that sort of thing.

594
01:07:22.430 --> 01:07:33.050
John Fronimos: I immediately pictured you know here one of those shrimps that gets you know mixed up in the settlement and buried, would you see any signs of you know escaped traces or anything like that those.

595
01:07:34.460 --> 01:07:36.230
John Fronimos: persist in this type of stuff.

596
01:07:36.410 --> 01:07:42.050
savrdce@auburn.edu: that's a real good question um My guess is that the shrimp probably we're.

597
01:07:43.490 --> 01:07:46.730
savrdce@auburn.edu: Assuming that that's how they were in placed okay.

598
01:07:48.110 --> 01:08:04.220
savrdce@auburn.edu: They were probably more part of a suspended load than, although that Sam was probably in suspension to i'm just guessing that the sand might have come down before they the floating bodies of shrimp but.

599
01:08:06.290 --> 01:08:10.100
savrdce@auburn.edu: I don't know that's a interesting interesting point.

600
01:08:11.870 --> 01:08:20.900
savrdce@auburn.edu: Most of the time when you see escape structures they're usually produced by something that was already on the sea floor or when you had rapid deposition.

601
01:08:22.700 --> 01:08:34.730
savrdce@auburn.edu: But something like this probably would have had a lot of erosion prior to deposition and would have re suspended, you know just looking at regular storm deposits in the trace fossils.

602
01:08:35.870 --> 01:08:51.050
savrdce@auburn.edu: You would think you would find a lot more escape structures and then but I don't hardly ever seen him and I think it's because the base of the V San are typically sharp and original and either the current or the wave energy has reached suspended.

603
01:08:52.910 --> 01:08:55.670
savrdce@auburn.edu: The mud, and probably organisms.

604
01:08:56.720 --> 01:09:09.170
savrdce@auburn.edu: And then eventually you get the sand and then you have things fall out, you know the finer grain tail of the event, so I don't see a lot of I don't see any escape structures, although.

605
01:09:10.580 --> 01:09:16.460
savrdce@auburn.edu: it's kind of hard to see in these buyers for beta intervals, specifically in the quake sans good vertical.

606
01:09:18.170 --> 01:09:20.570
savrdce@auburn.edu: profile, so there are a few places where you can.

607
01:09:21.200 --> 01:09:25.400
Rindsberg, Andrew: I did look at the vertical profiles and I don't remember seeing any escape structures.

608
01:09:25.490 --> 01:09:28.460
Rindsberg, Andrew: or anything except for the last invitees.

609
01:09:28.700 --> 01:09:28.940
Right.

610
01:09:31.910 --> 01:09:38.000
savrdce@auburn.edu: What do you think about that audrey you buy in the mega wave surfing shrimp where's he going with Andy.

611
01:09:40.370 --> 01:09:42.200
Rindsberg, Andrew: i'm just being skeptical i'm not saying.

612
01:09:44.150 --> 01:09:46.100
savrdce@auburn.edu: i'm just trying to spot.

613
01:09:47.060 --> 01:09:50.000
RISE GSA Audrey Heun: These surfing transom quite interesting.

614
01:09:50.780 --> 01:09:55.910
savrdce@auburn.edu: Well, I didn't mention that we found the surfboards about that big it's.

615
01:09:58.340 --> 01:10:00.020
savrdce@auburn.edu: evolved been lignin ties, but.

616
01:10:01.340 --> 01:10:02.660
savrdce@auburn.edu: In board with to read oh.

617
01:10:03.920 --> 01:10:05.090
RISE GSA Audrey Heun: Yes, i'm making me hungry.

618
01:10:09.230 --> 01:10:09.410
RISE GSA Audrey Heun: I.

619
01:10:10.190 --> 01:10:19.370
Rindsberg, Andrew: guess i'm far from time to throw in the towel chuck Bravo, this was an excellent field trip video and the next Q amp a.

620
01:10:20.450 --> 01:10:29.060
savrdce@auburn.edu: And I think you helped make it that way, because you've been there and had a lot to add, I appreciate it, but let's get out there sometime.

621
01:10:31.880 --> 01:10:34.190
Rindsberg, Andrew: vantage this summer i've been vaccinated.

622
01:10:35.420 --> 01:10:38.240
savrdce@auburn.edu: I second one I got two weeks i'll get started.

623
01:10:40.640 --> 01:10:41.870
savrdce@auburn.edu: In the water should be down.

624
01:10:42.860 --> 01:10:44.150
Rindsberg, Andrew: yeah summer.

625
01:10:47.840 --> 01:10:49.700
Rindsberg, Andrew: home resting there in the summer, but.

626
01:10:49.790 --> 01:10:51.680
Rindsberg, Andrew: But to see the only good time to go.

627
01:10:54.140 --> 01:10:54.800
Rindsberg, Andrew: to slip on.

628
01:10:54.890 --> 01:10:56.630
Rindsberg, Andrew: That truck really is slick.

629
01:10:57.560 --> 01:10:57.800
yeah.

630
01:11:01.880 --> 01:11:02.840
RISE GSA Audrey Heun: So thank you.

631
01:11:02.900 --> 01:11:03.980
RISE GSA Audrey Heun: audrey yeah.

632
01:11:04.010 --> 01:11:05.960
RISE GSA Audrey Heun: Thank you fun working with you on this stuff.

633
01:11:06.200 --> 01:11:08.990
savrdce@auburn.edu: yeah thanks all of you guys at GSA it's.

634
01:11:10.220 --> 01:11:12.740
savrdce@auburn.edu: It seemed painless well thanks.

635
01:11:16.280 --> 01:11:24.500
John Fronimos: truck I wanted to say thank you being being new to the area, you know coming here this past year and still getting a feel for you know the.

636
01:11:25.130 --> 01:11:35.510
John Fronimos: locals photography and geology and things I was a great primer on a lot of them both the first photography and the the general the specific things that make this outcrop so interesting.

637
01:11:35.810 --> 01:11:37.700
Rindsberg, Andrew: Good Where are you located.

638
01:11:39.020 --> 01:11:49.460
John Fronimos: So i'm here at auburn now i'm a lecture on the department, but I just got hired this past fall mean down from vassar and so i'm crash coursing myself and.

639
01:11:50.540 --> 01:11:56.120
John Fronimos: You know I always like to get a feel for this retainer fee as fast as I can but it's sort of yeah.

640
01:11:56.480 --> 01:12:01.610
savrdce@auburn.edu: very long on retired in June, when I did run Louis.

641
01:12:03.350 --> 01:12:04.640
savrdce@auburn.edu: And he's been really hiding.

642
01:12:09.800 --> 01:12:11.090
Rindsberg, Andrew: Know darn you you move.

643
01:12:12.230 --> 01:12:17.330
Rindsberg, Andrew: Across country and during the pandemic and set up a new office and all everything.

644
01:12:17.960 --> 01:12:19.550
John Fronimos: That was interesting it was interesting.

645
01:12:21.170 --> 01:12:21.950
John Fronimos: It was probably about.

646
01:12:23.030 --> 01:12:34.910
John Fronimos: A little earlier than this last year that I was interviewing I was supposed to come down to auburn and then suddenly they said hey we're not traveling anymore rob you know reasons that we're quickly becoming obvious a.

647
01:12:37.130 --> 01:12:39.710
John Fronimos: little bit different from other other moves i've done.

648
01:12:41.510 --> 01:12:52.370
Rindsberg, Andrew: Well you're better off than the you who the biologists who almost became a member of our faculty our our hiring process just collapsed.

649
01:12:55.520 --> 01:12:58.640
John Fronimos: Right after I you know got this position, the.

650
01:13:00.050 --> 01:13:05.060
John Fronimos: You know, seeing that the job listing sort of dry up and things.

651
01:13:07.310 --> 01:13:08.690
savrdce@auburn.edu: Well we're glad you're here john.

652
01:13:13.400 --> 01:13:14.300
Rindsberg, Andrew: Welcome to Alabama.

653
01:13:15.980 --> 01:13:19.520
John Fronimos: Thanks i'm glad to be here glad to circuit and know the area.

654
01:13:21.230 --> 01:13:21.740
savrdce@auburn.edu: Okay.

655
01:13:22.490 --> 01:13:23.360
John Fronimos: So you actually get.

656
01:13:23.420 --> 01:13:25.250
Rindsberg, Andrew: Along with when chuck.

657
01:13:26.000 --> 01:13:28.280
Rindsberg, Andrew: comes together let's go come along.

658
01:13:29.060 --> 01:13:32.510
John Fronimos: i'm glad to come along on any any outing I can get.

659
01:13:35.810 --> 01:13:40.880
savrdce@auburn.edu: Well, I hope everybody has a good Easter weekend yeah I gotta go home and eat fish.

660
01:13:47.270 --> 01:13:47.840
Rindsberg, Andrew: Good fish.

661
01:13:49.910 --> 01:13:50.690
Rindsberg, Andrew: good night everyone.

662
01:13:52.400 --> 01:13:54.000
savrdce@auburn.edu: Thanks, for attending.

savrdce@auburn.edu: Thanks, for attending.
