1
00:00:00.001 --> 00:00:11.120
Randy Kath: It is 1130 so we'll go ahead and get started, our first presentation today will be by Michael trippy Michael will be presenting a new cross section in the central.

2
00:00:11.900 --> 00:00:26.510
Randy Kath: appalachian central Alabama illustrating the regional and structural and strata graphic framework in the valley and Ridge province in southern appalachian basin so very excited to see this poster and i'll go ahead and see if I can get it.

3
00:00:26.780 --> 00:00:27.680
Presenting.

4
00:00:29.750 --> 00:00:34.580
Randy Kath: If you can just give me a thumbs up or raise your hand, let me know that you're seeing the poster okay.

5
00:00:37.940 --> 00:00:38.750
mtrippi: yeah, we can see it.

6
00:00:39.080 --> 00:00:47.120
Randy Kath: Okay, great so let me go ahead and play this is way too heavy for us, yes, the beginning thanks for coming to my poster.

7
00:00:47.660 --> 00:00:54.890
Randy Kath: And this point, please expand the videos so it fills you screwed So you can see all of my sites, thank you.

8
00:00:55.670 --> 00:01:08.060
Randy Kath: The title of the poster is blue cross section in central Alabama illustrating the regional structure and span rapid framework of the valium range province in the southern appalachian face.

9
00:01:09.470 --> 00:01:30.410
Randy Kath: there's a map showing some previously published cross sections by the usgs to the appalachian basin and worked on five star sections, the red line you see in Alabama is the location of the current cross section and black lines are the locations of some other cross section we both work.

10
00:01:33.170 --> 00:01:35.480
Randy Kath: there's a close up of those same cross section.

11
00:01:37.970 --> 00:01:49.850
Randy Kath: And this is a close up of the crime cross section which starts on the South, was to the county and it passes to hale county Perry county and and in it.

12
00:02:06.290 --> 00:02:09.500
mtrippi: I think it's muted can't hear it anymore.

13
00:02:09.920 --> 00:02:10.250
he's.

14
00:02:11.600 --> 00:02:15.080
Randy Kath: able to hear his voice to the map and the other colors.

15
00:02:15.110 --> 00:02:16.130
mtrippi: Now we can you.

16
00:02:16.520 --> 00:02:19.400
Randy Kath: heard of the map, or the paleozoic rocks.

17
00:02:21.620 --> 00:02:35.330
Randy Kath: And here is a strat column with the cretaceous and return rock and then carboniferous developments learning rocks including upper development and shadow the Shell, which is a potential source of shale gas.

18
00:02:36.470 --> 00:02:51.470
Randy Kath: And the early admission and camry interaction cool kind of saga formations use unknown source of shale gas, the lower two units and the cambrian and chill how he and shamed or might may or may not exist in this process.

19
00:02:54.050 --> 00:03:13.460
Randy Kath: Now here are the wells that we're using the Cross section six of these wells were previously news in a bb prime cross section of passion 2011 is our SP a report and those really athletic coach the baby etheridge.

20
00:03:16.070 --> 00:03:25.790
Randy Kath: And the to go stays paper company wells, and we added two other wells intake and university of Alabama well.

21
00:03:27.200 --> 00:03:38.480
Randy Kath: As the actual cross section shattering pretty good vertical exaggeration one foot sorry one inch vertically is 1000 feet.

22
00:03:38.870 --> 00:03:50.000
Randy Kath: And one inch horizontally is three miles so it's about what the 15 vertical exaggeration, as you can see the faces on left slopes off to the left.

23
00:03:50.450 --> 00:04:02.720
Randy Kath: And the blue areas underneath it are thrust sheets the bottom one is the one spreadsheet and the top one is Back to School Fresh sheet, which is display off in the corner.

24
00:04:03.320 --> 00:04:12.140
Randy Kath: they're both moving away from us into the page to the Northwest we just cut off the nose in them that's why you see a small or.

25
00:04:14.030 --> 00:04:23.360
Randy Kath: they're both thrust on top of the pottsville formation, which, on the right side, you can see, contains a number of different cool beds in the cahaba call.

26
00:04:24.710 --> 00:04:34.550
Randy Kath: In the middle part of the cross section, you see the devonian chattanooga and other shales which are potential source of shale gas.

27
00:04:36.200 --> 00:04:51.470
Randy Kath: At the bottom, we are blog faulting in the healing sorry precambrian basement rocks lower block fall on the right and the steps going down to the lower level in the middle, are the.

28
00:04:52.190 --> 00:05:08.090
Randy Kath: Birmingham grounded and the Birmingham grab it is filled with no information and above that kind of side of formation and in certain places, you see a kind of sorta formation founded at the top and bottom by thrust falls.

29
00:05:08.510 --> 00:05:25.700
Randy Kath: area in between the best summer much law, which is highly contorted shells finally on the far left there are three ramp thrust faults and those are the ones, described by passion in 2011 and Robinson in 2012.

30
00:05:26.180 --> 00:05:35.750
Randy Kath: And i'm just about out of time now, so thank you for watching the slides and hope you enjoy the day bye bye.

31
00:05:39.170 --> 00:05:43.460
Randy Kath: Okay sorry about muting you Michael there at the beginning.

32
00:05:43.820 --> 00:05:44.390
mtrippi: No problem.

33
00:05:44.810 --> 00:05:51.920
Randy Kath: yeah I didn't realize, I was trying to mute myself to be quiet and it muted, the whole thing, so I apologize.

34
00:05:52.940 --> 00:05:53.360
mtrippi: Okay.

35
00:05:54.590 --> 00:05:59.780
Randy Kath: So um does anybody have any questions trying to see where my chat window is.

36
00:05:59.900 --> 00:06:08.630
mtrippi: Before before anybody has any questions, I just want to apologize for the pixelated images on the actual poster.

37
00:06:10.130 --> 00:06:11.750
mtrippi: I was thinking, this was the.

38
00:06:13.250 --> 00:06:26.630
mtrippi: The preview mode someone told me, this would be the preview mode and then the actual PDF would be available to look at, but no Apparently, this is the only image that's available which.

39
00:06:27.950 --> 00:06:32.510
mtrippi: it's a PNG that they created from the PDF that I sent them.

40
00:06:33.440 --> 00:06:36.050
mtrippi: You could see the PDF it would really look great.

41
00:06:38.090 --> 00:06:44.180
Randy Kath: Well, and Michael I think that the slide presentations you know look like very good quality.

42
00:06:44.390 --> 00:06:52.910
mtrippi: yeah those are better So if you look at the slides and freeze them, you know you can look a little bit closer and see.

43
00:06:54.020 --> 00:07:00.020
mtrippi: See the detail, but unfortunately the actual poster here is pretty pixelated.

44
00:07:01.970 --> 00:07:12.950
Randy Kath: Well we'll have to discuss with GSA and see you know when they archive these if we can update the p amp g to P PDF a higher higher level higher Greg.

45
00:07:13.430 --> 00:07:18.170
mtrippi: yeah Jennifer no Sir, you know, told me that they would probably do that.

46
00:07:18.530 --> 00:07:20.990
Randy Kath: yeah yeah Jennifer is pretty easy to work with and.

47
00:07:22.430 --> 00:07:26.990
Randy Kath: I am, I am not seeing my chat window, so I don't know if there's any.

48
00:07:27.650 --> 00:07:29.420
mtrippi: You know i've got a here let's see.

49
00:07:33.590 --> 00:07:36.290
mtrippi: i'm not seeing any questions from anyone.

50
00:07:38.240 --> 00:07:45.530
mtrippi: There is a statement there from Andy about his presentation.

51
00:07:45.530 --> 00:07:48.950
Randy Kath: That I just found my chat and I got the last audios here.

52
00:07:49.490 --> 00:07:49.760
mtrippi: yeah.

53
00:07:50.270 --> 00:07:54.500
Randy Kath: So, so any questions we have a few minutes i've got a question for you.

54
00:07:54.560 --> 00:07:54.950
Okay.

55
00:07:56.870 --> 00:08:02.780
Randy Kath: there's been a lot of exploration and the appalachian basin and Alabama and Georgia.

56
00:08:03.500 --> 00:08:08.210
Randy Kath: And a lot of the shale gas you they're looking at the condo saga and chat, of course.

57
00:08:08.240 --> 00:08:08.570
sure.

58
00:08:09.710 --> 00:08:19.880
Randy Kath: And I was just curious in these in these robbins that you're showing and we've got you know thick Roman and kind of saga in there.

59
00:08:20.300 --> 00:08:25.640
Randy Kath: I was just curious if you're able to pick up the House because there's been a lot of.

60
00:08:25.730 --> 00:08:28.100
Randy Kath: there's a couple special trips.

61
00:08:28.370 --> 00:08:30.380
mtrippi: So i've been discussing that with.

62
00:08:31.400 --> 00:08:32.930
mtrippi: Jim Coleman and.

63
00:08:34.520 --> 00:08:35.930
mtrippi: bill Thomas and.

64
00:08:38.090 --> 00:08:51.290
mtrippi: Especially Jim Coleman had some maps that he created a 20 years ago, when he was working with I I believe its shell, and they were drilling in the.

65
00:08:53.180 --> 00:08:55.010
mtrippi: In the canoe Valley.

66
00:08:56.360 --> 00:09:14.990
mtrippi: basin, which is a it's North East of here, but that that was the first place where they started drilling into the the Marsh watch for for gas, and so, at that time he created this map showing the thickness of the shady dolomite.

67
00:09:16.370 --> 00:09:18.350
mtrippi: On top of that show how he and.

68
00:09:19.400 --> 00:09:23.480
mtrippi: It pretty much Peters out by the time you get.

69
00:09:24.890 --> 00:09:32.180
mtrippi: Really any distance to the Northwest, and so I don't think it's really present in this area.

70
00:09:33.620 --> 00:09:38.270
mtrippi: But it's hard to know, because we don't have any wells in penetrate that deep and.

71
00:09:39.380 --> 00:09:44.750
mtrippi: If if it's there at all it's very, very sin, you know.

72
00:09:44.810 --> 00:09:45.170
Okay.

73
00:09:47.870 --> 00:09:57.080
Randy Kath: I was just curious because, as you go up to the Northeast right on Alabama Georgia line up in the mountain areas, the tool, how it gets pretty thick in there.

74
00:09:57.380 --> 00:10:06.950
mtrippi: It does yeah and and so, so does the shady and that's what Jim coleman's map code, but.

75
00:10:08.000 --> 00:10:23.960
mtrippi: Unfortunately, his map didn't go down into big county, but if you extend the the zero sickness contour into big eight it goes to the east of this cross section so.

76
00:10:24.380 --> 00:10:24.800
Randy Kath: Okay.

77
00:10:25.160 --> 00:10:26.480
mtrippi: So that's My guess but.

78
00:10:26.510 --> 00:10:28.970
mtrippi: I can't tell unless you.

79
00:10:29.360 --> 00:10:29.960
mtrippi: Actually.

80
00:10:30.350 --> 00:10:31.190
Randy Kath: You know right.

81
00:10:31.340 --> 00:10:32.690
mtrippi: There and phoned it, you know.

82
00:10:34.070 --> 00:10:38.030
Randy Kath: Oh, Michael thanks for that, though in the move on to the next poster.

83
00:10:38.960 --> 00:10:40.460
Randy Kath: And next poster.

84
00:10:40.940 --> 00:10:41.780
Randy Kath: Is a.

85
00:10:43.130 --> 00:10:43.880
by Bart.

86
00:10:46.160 --> 00:10:48.290
Randy Kath: Can snatch and Nicholas.

87
00:10:50.510 --> 00:11:05.600
Randy Kath: boss dog Sierra is art and Richard wooten, and this is the new one to 24,000 scale bedrock geologic map of the old for seven and a half minute quadrangle McDowell and Nancy counties North Carolina.

88
00:11:07.040 --> 00:11:09.890
Randy Kath: let's see if we can get that one up and playing.

89
00:11:13.520 --> 00:11:17.720
Randy Kath: Okay, and I believe seer is going to be presenting.

90
00:11:18.830 --> 00:11:27.350
Randy Kath: hi my name is yeah I don't I was in North Carolina geological survey, thank you for attending my presentation i'm doing logic mapping in the old work logical.

91
00:11:27.740 --> 00:11:34.100
Randy Kath: you'd like to view or download the official of about report, you can visit our website or contact the others.

92
00:11:34.970 --> 00:11:41.930
Randy Kath: But all of our quiet is looking in western North Carolina about 25 miles east of astral, which is one of the main reasons we chose as quiet.

93
00:11:42.320 --> 00:11:51.500
Randy Kath: As a desirable place to live and the surrounding areas are quickly developing the quietest awesome affected by the blue Ridge escarpment which separates the lower elevation.

94
00:11:52.190 --> 00:11:59.660
Randy Kath: From the higher elevation blue Ridge, which is there's a tendency for this is the area another one of the main reasons we chose this one.

95
00:12:00.890 --> 00:12:10.010
Randy Kath: Was situated in the Tutoring which is largely made up of medicine and volcanic rocks deposit of bread to continental oceanic crust.

96
00:12:10.610 --> 00:12:27.710
Randy Kath: bedrock of the magical could use the following units and undivided neoproterozoic been sedentary unit this inner layer within subway in Quebec shifts and your proteins of medicine, so of course for classified as a nice a nice Nice and violent violent awesome.

97
00:12:28.760 --> 00:12:38.750
Randy Kath: But my Pilates or the orange unit on the map and the bird provide fault is a prominent linear ne se striking feature extending from Alabama to Virginia.

98
00:12:39.440 --> 00:12:52.880
Randy Kath: It has a pretty complex history of multiple reactivation but during both the neo key and and allegheny and ronnie's the effects of this fault seen throughout the quadrennial with decreasing liberalisation hours from the fall.

99
00:12:54.470 --> 00:13:04.520
Randy Kath: So, you said that regard some isn't mixtapes unit and on the map, due to its proximity, with the braveheart all part of this identifications pretty difficult.

100
00:13:05.150 --> 00:13:12.590
Randy Kath: The units largely made up of heterogeneous by a nice continuing local criminal to grab a size for for fast food and passive layers.

101
00:13:13.370 --> 00:13:21.530
Randy Kath: layers and genetic ortho nice horses others by a tight Nice are probably related to the neoproterozoic to ask permission.

102
00:13:22.070 --> 00:13:42.260
Randy Kath: And, or to the or division nice so to move balls formation, is a fairly heterogeneous medicine momentary it's highly moment taken this Carolina while the Henderson nice it simple tallies is a criminal court, the Nice continue lots of people in our audience that are logging in the bullies.

103
00:13:43.280 --> 00:13:49.790
Randy Kath: And that sounds pretty different, but if you look at these two pictures at the bottom, you can see the similarities between all of them.

104
00:13:50.030 --> 00:13:57.440
Randy Kath: And then, adding that a lot of our crops in this unit or stabling and high weather, so it can make for a bit of a head scratcher in the field.

105
00:13:58.430 --> 00:14:13.130
Randy Kath: To add on top of that there's another board for classic by take place and it's in purple on the map usgs Tina preliminary hd a 360 million years old tentatively, making it making it devonian.

106
00:14:14.300 --> 00:14:25.580
Randy Kath: But powerful classes in unit or similar to the mix nice but they tend to be more in mueller and less elongated affiliation plane, which I think is illustrated best by our field term asphalt Nice.

107
00:14:26.360 --> 00:14:33.350
Randy Kath: In the Northwest the bottoms underlying by neoproterozoic cemetery units are probably correlated with the optionality to back.

108
00:14:34.760 --> 00:14:44.930
Randy Kath: These are the Gray and yellow units on the map largely the mythologies with an undivided unit very for medicine some dishes and anything in between plus and devil like.

109
00:14:45.620 --> 00:14:51.200
Randy Kath: All these mythologies were metamorphose to like a she's conditions during the two car garage me.

110
00:14:51.890 --> 00:15:06.230
Randy Kath: If you look at the slack mineral locations, that the medicine some unit was largely delineated from the rest of the medicine is because it uniquely does not contain garnishes or the light and we're thinking, this represents a shift deposition environment.

111
00:15:07.490 --> 00:15:13.880
Randy Kath: If you look at the Cross section, you can see that we are unsure of the contact relationship between the undivided better settlements.

112
00:15:14.060 --> 00:15:21.170
Randy Kath: And the medicine stone in the Northwest and some of those uncertainties stems from our debate on what constitutes ash for alligator back.

113
00:15:21.800 --> 00:15:36.260
Randy Kath: we're also ensure the exact nature between the medicine, so in the corporate classified as a nice, but we did see some evidence of extra strength of motion to provide fault it's the mix nice unit over the poor for classic it nice, but that should have leixlip motion.

114
00:15:37.640 --> 00:15:47.060
Randy Kath: Looking at the stereo and, as you can see that the mile a minute and Nonviolent medical issues within the quad Dolly straight north east, south west and did to the southeast.

115
00:15:47.720 --> 00:16:00.080
Randy Kath: The private practice that shakes my se and it's deeply debate, but there are a lot of minor factor sense as well, thank you for listening to my presentation and i'll do my best to answer any questions that you might have.

116
00:16:03.980 --> 00:16:15.920
Randy Kath: Alright, well, thank you, Sarah sorry about that michaels presentation, I had to maximize it, you can see the slides and on sierra's but I had to back minimize it thanks for the comments in the chat window.

117
00:16:16.400 --> 00:16:18.080
Sierra Isard: yeah don't worry about it okay.

118
00:16:18.650 --> 00:16:22.070
Randy Kath: yeah it looks like each one is going to be slightly different.

119
00:16:24.500 --> 00:16:26.720
Randy Kath: Does anybody have any questions for Sierra.

120
00:16:32.150 --> 00:16:35.270
Randy Kath: If you do feel free to admit I have a question for us here.

121
00:16:35.510 --> 00:16:36.260
Sierra Isard: Sure go ahead.

122
00:16:37.100 --> 00:16:39.980
Randy Kath: So you're provided fault zone, and we had a field trip.

123
00:16:41.210 --> 00:16:46.160
Randy Kath: When we had a field trip, I think it was Wednesday on Milan, is for mark skelton Paul.

124
00:16:46.610 --> 00:16:48.380
Randy Kath: Okay we're looking at the bard.

125
00:16:48.500 --> 00:16:57.140
Randy Kath: And had some very good discussions, and you know you're talking about quite a bit of movement nia katie and movement and allegheny and movement.

126
00:16:58.250 --> 00:17:06.950
Randy Kath: And one of the things we see down here associated with Milo nights and this year fabrics are the bird is there isn't a lot of movement.

127
00:17:07.700 --> 00:17:25.130
Randy Kath: We can we can track the fully ation right across fold noses in the fold noses aren't dissected and attenuated so i'm just curious what type of indicators, you have for movement net slip, if you will, on the barn.

128
00:17:26.510 --> 00:17:47.660
Sierra Isard: um well you know a lot of that is from prior a I guess research into it, not something that we have done, specifically, but if you look at the revered faults own in some of these quads you know, there are a lot of elongated portal class and.

129
00:17:48.920 --> 00:17:51.260
Sierra Isard: Like Buddha and magnetite.

130
00:17:52.490 --> 00:17:54.950
Sierra Isard: um, but I would say.

131
00:17:56.420 --> 00:18:02.690
Sierra Isard: I don't know how to answer your question I don't have anything I don't have a good answer for it to be honest.

132
00:18:03.020 --> 00:18:12.920
Sierra Isard: You know, we haven't done a lot of research into that and trying to figure out how much movement that we have personally seen and it's something that could be included in future work.

133
00:18:13.760 --> 00:18:17.720
Randy Kath: yeah well as many of you know, the bird is problematic.

134
00:18:18.920 --> 00:18:30.230
Randy Kath: We see the same thing in our backyard here in Georgia beautiful poor for classic mortal tales pervasive sheer fabric cuts everything we have catecholamines lights, we have mile nights.

135
00:18:30.920 --> 00:18:41.930
Randy Kath: But it looks like displacement is very small, on the bar so I was just curious when I heard you talking about multiple movement on that regard I was just curious how your quantifying that means movement.

136
00:18:42.740 --> 00:18:44.570
Sierra Isard: I would say i'm not personally quantify.

137
00:18:50.180 --> 00:18:51.170
Randy Kath: yeah very good.

138
00:18:52.640 --> 00:18:54.590
Randy Kath: Any other questions for Sierra.

139
00:18:55.310 --> 00:18:58.280
mark carter: Sierra was more how wide is there.

140
00:18:58.850 --> 00:19:07.400
Sierra Isard: Oh it's pretty wide like the fabrics we see an old four is almost essentially the entire quad.

141
00:19:09.230 --> 00:19:14.300
mark carter: you're seeing you're seeing kinematic indicators rotated port for blast.

142
00:19:14.390 --> 00:19:15.920
Sierra Isard: We are yeah.

143
00:19:16.010 --> 00:19:18.140
mark carter: across the entire width of the quarter and.

144
00:19:19.130 --> 00:19:27.740
Sierra Isard: Not the entire width but a good portion of it, I can't tell you the exact mileage right now but it's something that I could figure out for you, if you.

145
00:19:27.800 --> 00:19:29.720
mark carter: really wanted to know where we talk later.

146
00:19:30.320 --> 00:19:30.890
Okay.

147
00:19:32.090 --> 00:19:34.130
mark carter: Good luck in math very good looking at.

148
00:19:34.160 --> 00:19:37.970
Randy Kath: yeah very nice presentations here thanks.

149
00:19:40.970 --> 00:19:44.630
Randy Kath: Okay well wait just another minute if there aren't any other questions.

150
00:19:45.650 --> 00:19:47.810
Randy Kath: Just to make sure we keep on schedule here.

151
00:19:51.590 --> 00:19:54.830
Randy Kath: and hopefully i'll get this one right maybe the third one's a charm.

152
00:19:59.030 --> 00:20:01.280
Randy Kath: Okay, so our next presentation.

153
00:20:02.390 --> 00:20:04.880
Randy Kath: Part Kevin Nash, and Nicholas.

154
00:20:06.950 --> 00:20:09.260
Randy Kath: I don't matter of design.

155
00:20:12.470 --> 00:20:12.890
Sierra Isard: Doc.

156
00:20:12.950 --> 00:20:15.050
Randy Kath: files dog I should have that Thank you.

157
00:20:16.460 --> 00:20:18.080
Randy Kath: and Sierra is art and.

158
00:20:18.140 --> 00:20:36.020
Randy Kath: Bart will be presenting, and this is a new one to 24,000 scale bedrock geologic map of the northern half the Moffat hill seven have been a quadrangle, and this is an McDonald rutherford and boom comb county North Carolina and Bart will be presenting.

159
00:20:40.460 --> 00:20:47.450
Randy Kath: And let's see if we can go read my name is mark cat now, along with my co authors.

160
00:20:48.440 --> 00:20:59.030
Randy Kath: Here either North Carolina geological survey, like to thank you for taking time out of your station, and I do try to map of the market, your quadrangle McDowell back and refer counties.

161
00:20:59.570 --> 00:21:09.050
Randy Kath: To quick notes, first the poster covers the entire module quarter, not just the northern portion, as indicated in the title, since we finished quadrangle.

162
00:21:11.600 --> 00:21:19.040
Randy Kath: seconds what we're showing in the poster is not complete open about math because of the limitations of what we can do the digital medium format.

163
00:21:19.760 --> 00:21:26.870
Randy Kath: elements, such as the detail right descriptions geochemistry in July we'll review, you can request a free digital copy of the entire map i've gotten.

164
00:21:27.230 --> 00:21:41.480
Randy Kath: Any of the authors for by downloading from the north Carolina jewelers survey website, I also want to mention upfront that this map is partially funded by the US either statement Walker she was matt program we're thankful for their continued support.

165
00:21:42.500 --> 00:21:50.420
Randy Kath: Whereas the quadrangle Moffat hill is located in western North Carolina just east of asheville along the blue just started.

166
00:21:51.110 --> 00:22:00.200
Randy Kath: Its location shown by the Red box and the train man, as many of you probably know, escarpment is transition zone between the mountains and Piedmont busy graph provinces.

167
00:22:01.010 --> 00:22:14.600
Randy Kath: High elevation of the quadrangle is 3604 feet and low elevation is 1057 feet, so we have the total relief of 2540 70 and it can be a really good place to work times.

168
00:22:15.260 --> 00:22:23.810
Randy Kath: Why did we choose this quadrangle map, although the quartering was predominantly rural it is located in close proximity to asheville and light blue are.

169
00:22:24.140 --> 00:22:31.640
Randy Kath: There lots of secondary vacation homes being built in the area, including several very large developments issues are particularly important.

170
00:22:32.000 --> 00:22:42.770
Randy Kath: Water resources, since all infrastructure years served by private wealth and other major problems landslides, especially debrief low to the high relief terrain see a couple of photos there.

171
00:22:43.340 --> 00:22:52.130
Randy Kath: and other issues, the presence of elevated levels of rate on air and grab a water and a frenetic bodies of the area we're hoping that the new data generator aromatic.

172
00:22:52.580 --> 00:23:00.410
Randy Kath: and assist with some of these issues geologically the quality is contained entirely within the two blue drain of laurentian infinity.

173
00:23:01.100 --> 00:23:07.160
Randy Kath: provides them the sliver of Orange shown on the map bisects to do the train across the northern part of the quad.

174
00:23:07.550 --> 00:23:18.860
Randy Kath: Like sub quadrant goes along strike, we did not identify any regard sounds cynical apologies that regards out here seems to be just a moment to strengthen over branding ash loose balls or mention units.

175
00:23:19.370 --> 00:23:27.410
Randy Kath: That being said, that separate to be organized said, although similar interference to one another locally, have very different radio mentor gauges.

176
00:23:28.010 --> 00:23:41.060
Randy Kath: So what did we what you instantly find or define on the path from Northwest southeast on the cross section line we identified six units, the first is new Yorkers are cambrian aged ashman work.

177
00:23:42.200 --> 00:23:45.890
Randy Kath: and show and yellow here's a quick example medicine so.

178
00:23:46.850 --> 00:23:56.240
Randy Kath: Next, we have a port requested by type organized unit that intrudes and his inner layered with other astronauts apologies, including medicine sounds just as good lights.

179
00:23:56.870 --> 00:24:06.890
Randy Kath: The unit is a purplish blue cover on the map and organized opponent has an approximate 368 year old age, bring to Ryan mcaleer of usgs.

180
00:24:07.580 --> 00:24:17.330
Randy Kath: we're very thankful to Ryan Arthur and mark Carter of the usgs for that age dates the unit is proud about it come on the most areas be to provide some information.

181
00:24:18.260 --> 00:24:30.230
Randy Kath: Moving to the southeast along the Cross section line with cross into a mix nice unit shown in dark pink that includes 450 year old interest nice it's your layered with to the false biotech nicest.

182
00:24:30.650 --> 00:24:41.930
Randy Kath: nicest and civilized so it's a mixed bag moving to the southeast we enter larger bodies of Henderson is shown in salmon cover and we also see 438 million year old.

183
00:24:42.320 --> 00:24:58.040
Randy Kath: clinic organized you know I paint color filing in southeast corner, we have a light yellow covered or division format information sandstone and a good light unit didn't trust contact with the underlying ortho paradises you can see the progression here the Cross section.

184
00:24:59.120 --> 00:25:06.590
Randy Kath: The cross section through and show that police quadrangle dominant restraint or the southwest and gives deeply devoted to the southeast.

185
00:25:07.370 --> 00:25:13.820
Randy Kath: You can see general Shell and creative affiliation, as you travel se across departments, they documented elsewhere on strike.

186
00:25:14.720 --> 00:25:29.720
Randy Kath: The product attractor set strikes Northwest southeast and a steeple debbie all of these rocks of underground and people like basis and what visible some experiencing partial melting as expected rocks into the zone also locally experience creatures bases retrogression.

187
00:25:31.250 --> 00:25:37.220
Randy Kath: The hopefully this interesting gave you the flavor of the quadrangle and happy to help answer any questions you may have.

188
00:25:41.060 --> 00:25:45.980
Randy Kath: Okay, thank you very much, very nice presentation, do we have any questions for BERT.

189
00:25:49.550 --> 00:25:49.940
Bart Cattanach: ready.

190
00:25:51.560 --> 00:25:52.460
Bart Cattanach: Okay, go ahead mark.

191
00:25:52.850 --> 00:25:56.960
mark carter: i'm sorry, no, no, you go ahead, please, I talked boarding time or i'll finish right.

192
00:25:57.710 --> 00:26:03.770
Bart Cattanach: Now I was gonna thank Randy really quickly and then also it's going to address one of his questions.

193
00:26:03.830 --> 00:26:11.990
Bart Cattanach: To Sierra as well as one of your questions mark with the thickness can I share my screen is that allowed.

194
00:26:12.740 --> 00:26:17.780
Randy Kath: US yeah should be able to let me stop mind and see if you can click your share screen now.

195
00:26:19.520 --> 00:26:20.720
Bart Cattanach: If I can share.

196
00:26:21.830 --> 00:26:24.890
Bart Cattanach: The one at once, see if you can.

197
00:26:26.270 --> 00:26:27.980
Bart Cattanach: Can you see a very large.

198
00:26:29.930 --> 00:26:40.550
Bart Cattanach: yeah so the Moffat hill quadrangle is this guy right here, and you can see the reward zone as we haven't mapped here that the orange or the the magnetic.

199
00:26:40.970 --> 00:26:49.070
Bart Cattanach: These are actual mile and i'd say mom and I units and that, for us as a cop out when we can't determine we don't feel like we can determine the production on these things.

200
00:26:50.270 --> 00:26:52.010
Bart Cattanach: So, as far as.

201
00:26:53.090 --> 00:27:04.070
Bart Cattanach: You know I wouldn't put any kind of distance on shearing but I will say that the provided so here truncate CC this sandstone unit coming down some of the other asheville theologies.

202
00:27:04.430 --> 00:27:11.120
Bart Cattanach: We do feel like they're strong out and truncated in this area, and then, of course, on the other side, you do have.

203
00:27:12.590 --> 00:27:19.910
Bart Cattanach: Like the Henderson nice mythologies which is not they're not present northeast to provide zone, so I think there is some amount of movement.

204
00:27:20.390 --> 00:27:33.740
Bart Cattanach: But I don't know how great it is and and mark for the thickness of the regard zone manifestation or defamation, we were feeling, you know down here in.

205
00:27:34.130 --> 00:27:45.530
Bart Cattanach: ot and bike mountain, it was only about a kilometer when you're sort of northeast of the central mom and I found was only about a kilometer that you would see the defamation, but it seemed to be much more widespread.

206
00:27:46.790 --> 00:27:54.800
Bart Cattanach: On the south eastern side, and as we move up into some of our other mapping, this is old board, this is what Sierra was discussing.

207
00:27:55.850 --> 00:28:02.450
Bart Cattanach: The defamation becomes more widespread, and of course the grandfather mountain window starts here and.

208
00:28:02.960 --> 00:28:20.150
Bart Cattanach: I think we may be seeing similar timing, but a couple of you know, maybe a display off the bard or a totally different fault but we're seeing a lot more of those magnetic and high sheer volume in here, and it does narrow down in this area.

209
00:28:21.980 --> 00:28:33.200
mark carter: yeah you're gonna have to bring that fault south of the window right there good splay out kind of winding up in that one area, but ultimately it's got to be at the beach in the southeast side of the window.

210
00:28:34.310 --> 00:28:37.220
mark carter: To the north right what's the name of the fault.

211
00:28:38.480 --> 00:28:45.590
mark carter: that separates your format for site from from your Henderson and your other Eastern blue Ridge are.

212
00:28:46.220 --> 00:28:51.290
Bart Cattanach: Those yeah so i'm wondering, I think that might be part of the sugar low at that point.

213
00:28:52.820 --> 00:29:08.000
Bart Cattanach: i'll have to go back and see there's we don't have any of the Nice, you know there's actually sugarloaf Nice that you can see, below that on a few, if you remember that one or not came out of Davis and yoga hora they're mapping around the Columbus problem story.

214
00:29:09.890 --> 00:29:13.070
Bart Cattanach: And so I think that would be the sugar low.

215
00:29:14.210 --> 00:29:14.480
Bart Cattanach: But.

216
00:29:15.560 --> 00:29:16.400
Bart Cattanach: i'll get back to you.

217
00:29:16.880 --> 00:29:21.020
mark carter: and your graphite is in your is in zone between the two faults there.

218
00:29:21.260 --> 00:29:30.800
Bart Cattanach: Yes, and that's actually another point, so we do find regards on mythologies in here, which include especially further down i'm not going to try to to.

219
00:29:31.280 --> 00:29:41.720
Bart Cattanach: Pan it now, but big large graphite is volunteer and those disappear on these this area, but we do see graphite in Griffith units.

220
00:29:42.110 --> 00:29:55.460
Bart Cattanach: up in this off what you know, is this display or what's going is just purely a lift the logic difference, so the graphite seem to go North year and doesn't follow along selfies of the grandfather window.

221
00:29:58.220 --> 00:29:58.970
mark carter: Right thanks.

222
00:30:00.770 --> 00:30:02.120
Randy Kath: A great discussion there and.

223
00:30:03.650 --> 00:30:08.900
Randy Kath: Okay, so if you can and share your screen Bart will carry on.

224
00:30:09.380 --> 00:30:11.660
Bart Cattanach: I will try and soon as I can.

225
00:30:13.400 --> 00:30:13.760
Bart Cattanach: yeah.

226
00:30:13.970 --> 00:30:14.840
Yes.

227
00:30:16.520 --> 00:30:17.090
Randy Kath: perfect.

228
00:30:18.830 --> 00:30:22.550
Randy Kath: Okay, I see where I am so let me share my screen back.

229
00:30:24.200 --> 00:30:25.130
Randy Kath: And we'll get back.

230
00:30:26.390 --> 00:30:38.360
Randy Kath: 12 o'clock Charles Michael and kyle galinsky pleistocene geology of the northwestern heart and Eastern Marion county South Carolina or horry.

231
00:30:40.580 --> 00:30:43.160
Randy Kath: Andy Is this the one that you were going to share your screen.

232
00:30:43.220 --> 00:30:45.890
mtrippi: that's fine you don't want to give them that again.

233
00:30:47.510 --> 00:30:48.020
mtrippi: i'm.

234
00:30:48.650 --> 00:30:52.280
Andy: know, though, that isn't the one I was going to share, but I can share my screen, if you would like me to you.

235
00:30:53.120 --> 00:30:58.190
Randy Kath: Okay, so this there's this one doesn't have a video with it.

236
00:30:59.270 --> 00:31:01.370
Andy: No i'm just gonna wing it live.

237
00:31:02.330 --> 00:31:02.750
Okay.

238
00:31:04.760 --> 00:31:08.000
mtrippi: Let me get back his poster that's my poster so.

239
00:31:08.060 --> 00:31:13.850
Randy Kath: yeah yeah so let me switch supine get your poster back sorry.

240
00:31:17.960 --> 00:31:19.820
Randy Kath: We don't want to join i'm already there.

241
00:31:26.210 --> 00:31:28.550
Randy Kath: Okay let's get back to where we were.

242
00:31:36.800 --> 00:31:40.310
Randy Kath: heather I don't know if you're still here, I may have lost the meeting.

243
00:31:41.990 --> 00:31:43.430
Randy Kath: blessed to have everyone with us.

244
00:31:43.820 --> 00:31:44.600
RISE GSA Staff Heather Clark: i'm still here.

245
00:31:45.410 --> 00:31:46.280
mtrippi: yeah here you.

246
00:31:48.590 --> 00:31:50.570
Randy Kath: appear to have lost the meeting.

247
00:31:52.970 --> 00:31:54.350
Randy Kath: it's just I can get back.

248
00:31:58.700 --> 00:32:00.140
Randy Kath: To the 12 o'clock.

249
00:32:04.550 --> 00:32:06.260
Randy Kath: Okay, you seen that poster now.

250
00:32:08.000 --> 00:32:09.860
Randy Kath: Yes, okay sandy.

251
00:32:12.950 --> 00:32:15.890
Randy Kath: sorry about that will give you a couple extra minutes at the end there.

252
00:32:16.520 --> 00:32:18.740
Andy: yeah no worries, my goodness start.

253
00:32:19.160 --> 00:32:19.970
Randy Kath: Yes, you're good to go.

254
00:32:20.360 --> 00:32:31.250
Andy: Okay awesome well i'm my name is Charles like Dell, but I go by amy sorry for the confusion and I worked at the South Carolina geological survey, and today I will be presenting.

255
00:32:31.880 --> 00:32:41.750
Andy: was made by myself and called the wind speed and titled places in geology of northwestern ori and Eastern Marion county South Carolina.

256
00:32:43.190 --> 00:32:49.880
Andy: The math area is in the Atlantic coastal plain, specifically the lower coastal plain of northwestern worry and Eastern Marion counties.

257
00:32:50.900 --> 00:33:09.230
Andy: For quadrangles dunford Nichols Galvin sperry and baber were map to the 7.5 minute one to 24,000 scale 126 four holes were drilled and log to cover a total depth of 6779 feet, with an average little depth of 53 point.

258
00:33:10.250 --> 00:33:17.540
Andy: Once field work was complete the magical made with the help of lidar and aerial photography and our GIs and finalized in adobe illustrator.

259
00:33:18.440 --> 00:33:27.470
Andy: At the surface three places in our formations were identified a nap which were the waikato Allah formation, with an age around 1.2 million years old.

260
00:33:27.920 --> 00:33:36.170
Andy: depend Holloway all information with an age of around 100,000 years old and the lads and information within a around 450,000 years old.

261
00:33:36.950 --> 00:33:49.490
Andy: We were also able to identify force louisville terraces at the surface or crane and each in each quadrangle designated as terrorists 123 and four was for being the oldest deposits in one being the youngest departments.

262
00:33:50.060 --> 00:33:57.170
Andy: Each younger terrorist is separated from the older terrorists by a subtle but malleable sharp decrease in elevation a scar.

263
00:33:58.070 --> 00:34:07.010
Andy: Normally the luteal terraces would be grouped with their associated information, but as of now, the kind of strata graphic relationship to be our formations is unknown.

264
00:34:07.760 --> 00:34:21.740
Andy: As can be seen from the maps the places seem deposits are significantly modified at the surface from ordinary features such as Carolina bs and 60 sanatoriums a only in sand creeps swaps, and of course anthropogenic influence.

265
00:34:22.760 --> 00:34:32.900
Andy: In the subsurface several marine units in Bolivia unit were identified the flu Bo unit is unnamed inconsistent pliocene to place a simpler you'll sand.

266
00:34:33.710 --> 00:34:41.960
Andy: And unnamed locked into the clay occurs throughout the map area and based on upper and lower services is either pliocene to pleistocene and age.

267
00:34:42.380 --> 00:34:51.110
Andy: The drupal information in the goose creek formation were identified as Court says show has stains and, of course, the quotations PD formation was also identified.

268
00:34:52.190 --> 00:35:00.650
Andy: The main story of the of this map of the mapping in this poster is the complex luteal history of the area, as can be seen from the Cross sections.

269
00:35:01.490 --> 00:35:11.630
Andy: Paleo channels heavily alter the subsurface expression of the PD formation these Paleo channels are commonly infill in filled with the goose creek and duplicate formations.

270
00:35:12.080 --> 00:35:17.810
Andy: The topographic loose created by these pillars channels likely protected these units meridian by later transgressions.

271
00:35:18.320 --> 00:35:25.940
Andy: Also supplies into place to St Louis will sand can be seen instilling Paleo channels cut into both the goose creek and the Dupont formations.

272
00:35:26.600 --> 00:35:35.780
Andy: In all likelihood, this subsurface bluegill yet is probably similar similar to the full reveal terraces circus in represents many different time periods, but more work.

273
00:35:36.320 --> 00:35:46.220
Andy: And dating techniques are are required to prove that another important topic is another important topic of discussion is elevations with the y comma your screen deposits.

274
00:35:46.820 --> 00:35:55.250
Andy: Our formations are commonly identified using spark to elevations a scarf Joe is the location where younger sentiments about order so sediments.

275
00:35:55.850 --> 00:36:02.330
Andy: At the scarf to s3 and deposits of the younger deposit mark the meantime tied elevation of the younger transgression.

276
00:36:02.870 --> 00:36:13.880
Andy: And previous work has identified tamika s3 and deposits doing it 90 feet of elevation However, these maps with identified my comic or s3 deposits elevations greater than 100 seat.

277
00:36:14.660 --> 00:36:22.730
Andy: While this discrepancy is problematic for correlation the map area is more proximal to the Cape fear arts and previously, not more common code surfaces.

278
00:36:23.180 --> 00:36:37.880
Andy: Higher why komodo s3 and elevations could be a result of Cape fear arch uplift and the construction of regional cross sections structure bumper maps and ice packs good produced on addressing the problem in long standing questions about cake, there are jumping.

279
00:36:38.990 --> 00:36:41.180
Andy: And that includes my talk.

280
00:36:43.040 --> 00:36:49.670
Randy Kath: Alright, well, thank you Andy and for our discussion I can zoom in on a particular portion of the map if you'd like to.

281
00:36:50.630 --> 00:36:52.310
Andy: Okay yeah that'd be great i'm.

282
00:36:53.480 --> 00:36:56.510
Randy Kath: Just tell me where you want to zoom and I think I can zoom in for you.

283
00:36:57.350 --> 00:37:01.040
Andy: Okay sounds good, I just did anybody have any questions for zoom in right now.

284
00:37:09.320 --> 00:37:14.480
Andy: i'm Sorry, I guess, we can zoom in on the third cross section.

285
00:37:18.860 --> 00:37:21.560
Andy: Specifically in this cross section, we can see.

286
00:37:22.670 --> 00:37:31.940
Andy: The Paleo channels heavily alter that bottom unit there at the Cross section is the cretaceous PD formation and, as we can see it's heavily altered by Paleo channels.

287
00:37:32.870 --> 00:37:39.650
Andy: The Orange unit sitting right above, it is the goose creek formation and adjacent to that the purple unit is.

288
00:37:40.580 --> 00:37:57.290
Andy: Go to the right sorry this one is the duplicate formation, so these pillow channels are commonly in filled with pliocene Court says show has sands and then above this carving into these two units is our unnamed pliocene to pleistocene full review unit.

289
00:37:59.930 --> 00:38:02.870
Andy: um but yeah that's pretty much all I have.

290
00:38:03.350 --> 00:38:03.890
Randy Kath: Great hey.

291
00:38:10.070 --> 00:38:16.850
Randy Kath: I realized that I can zoom in so if anyone else needs me to zoom on the presentation just let me know, and I can zoom in for you.

292
00:38:19.640 --> 00:38:22.670
Randy Kath: Okay, any other questions comments.

293
00:38:24.920 --> 00:38:30.650
Randy Kath: I have one quick comment Andy is the what is the vertical exaggeration on these cross sections.

294
00:38:31.250 --> 00:38:34.340
Andy: Vertical exaggeration on these cross sections is 100 to one.

295
00:38:34.910 --> 00:38:36.560
Randy Kath: OK, so the quite a bit yeah.

296
00:38:37.040 --> 00:38:37.490
Randy Kath: All right.

297
00:38:37.730 --> 00:38:38.660
Andy: A lot yeah.

298
00:38:43.610 --> 00:38:45.200
Randy Kath: Any other questions.

299
00:38:50.300 --> 00:39:03.230
Randy Kath: We can wait, just a few more minutes here and any questions from the previous presentation we got a couple minutes we could kill if anyone wants to pass continue on talking with Bart about any comments.

300
00:39:10.340 --> 00:39:13.520
Beth McClellan: I had one for Bart he's still here.

301
00:39:17.060 --> 00:39:27.800
Beth McClellan: Okay, this is just a real, specific question about the ash alligator back, I think you, you have that as neoproterozoic Is that correct.

302
00:39:28.340 --> 00:39:44.750
Beth McClellan: Yes, okay yep which is fine with me, I was just wondering, because I know, in the past, it had been interpreted as paleozoic, and so I was wondering what the latest age constraints that we have on this.

303
00:39:45.110 --> 00:39:57.080
Bart Cattanach: You know, for our our neck of the woods, we don't have any new age constraints, we do I i'd be happy to take it into paleozoic we can't take it, you know I think you couldn't take it very far into the automation but.

304
00:39:58.310 --> 00:39:59.630
Bart Cattanach: We don't have any.

305
00:40:00.950 --> 00:40:09.050
Bart Cattanach: Just because of the metamorphosis that we feel has affected the ash, but I don't have any specific dates, unfortunately.

306
00:40:11.000 --> 00:40:22.010
Bart Cattanach: You know now mark I don't know if mark still on here or not, but they've been working up in Virginia and they've got it in a little different strata graphic section i'm going to be quiet and I could talk forever, but.

307
00:40:23.240 --> 00:40:27.680
Randy Kath: Maybe at the end, we could open that back up but we'll move on to the next presentation.

308
00:40:28.820 --> 00:40:42.290
Randy Kath: geology seismic hazards of lauderdale and Tipton county Tennessee Valerie Harrison and Roy and heirs of an error stale and Chris Kramer and Valerie will be presenting.

309
00:40:47.000 --> 00:41:02.570
Randy Kath: Good morning, everyone, my name is Valerie Harrison, and I will be presenting the 3D geology and seismic hazards of lauderdale and counties in Tennessee the study was conducted at the University of memphis department of Sciences, as well as the Center for earthquake research and information.

310
00:41:03.680 --> 00:41:13.640
Randy Kath: As a part of an ongoing seismic and liquefaction hazard mapping project funded by the US Department of housing and urban development under a disaster resilience competition grants.

311
00:41:14.000 --> 00:41:22.310
Randy Kath: Details surface and subsurface geology of five Western Tennessee counties have a map, it represents the results for lauderdale and cities counties.

312
00:41:22.790 --> 00:41:28.760
Randy Kath: county 3D geologic models are constructed to it says earthquake Graham motion and liquefaction potential.

313
00:41:29.480 --> 00:41:41.030
Randy Kath: For whole water well sounds good reflection data, and so they were compiled for these counties, the resulting data says provide thickness and elevation of the top of the ECM Jackson formation.

314
00:41:41.450 --> 00:41:48.350
Randy Kath: You seem that the sandwich is the regional offer cretaceous out creek formation and elevation of paleozoic.

315
00:41:49.820 --> 00:41:55.040
Randy Kath: For each stratigraphy formation and unfolded and faulted structure contour map is made.

316
00:41:55.550 --> 00:42:10.820
Randy Kath: The archive data provide important information for the assessment of ground motion in the event of a large magnitude proximal earthquake, the 3D model also revealed windows through the Jackson formation may expose the underlying nervous and Rachel October to serve.

317
00:42:12.950 --> 00:42:21.260
Randy Kath: You think elevation information from 10 meter by send me your light RDS the near service geology was classified into three categories Lola.

318
00:42:23.390 --> 00:42:32.090
Randy Kath: Lola and intermediate contact elevation varies by county and these figures loads of water building was equal to 81 years until.

319
00:42:33.230 --> 00:42:34.400
Randy Kath: they're able to eight.

320
00:42:35.450 --> 00:42:39.050
Randy Kath: intermediate upon contract is constant element in 70.

321
00:42:40.130 --> 00:42:53.450
Randy Kath: The family patchy and humbled river terraces were added based on soft gaze 1987 years maps are classified as an intermediate terrorists have some of this project, their respective elevation saturday's attitude process.

322
00:42:54.440 --> 00:43:03.500
Randy Kath: Is your eyes cross sections do not represent any one place on their respective maps created using average thickness and elevation values related throughout.

323
00:43:05.930 --> 00:43:16.520
Randy Kath: For each stronger advocated of interest both unbolted altered structure puncher amazing water well with my exploration more whole and size like reflection data.

324
00:43:17.210 --> 00:43:25.760
Randy Kath: That you see Jackson formation is sheldon read the sand in production cretaceous out breathe in breathe and aliens out of knoxville and.

325
00:43:26.960 --> 00:43:31.880
Randy Kath: The unwanted services, along with data distribution for each formation or showing them the four fingers on.

326
00:43:33.200 --> 00:43:38.990
Randy Kath: The services are they using the natural neighbor contouring algorithm created this service.

327
00:43:40.340 --> 00:43:45.950
Randy Kath: Services sharp fingers on the right for creative using this wine with barriers contouring.

328
00:43:47.030 --> 00:43:52.520
Randy Kath: This technique considers all of these counties, with the resulting surfaces showing displacement.

329
00:43:54.140 --> 00:44:05.540
Randy Kath: overlay of the Jackson formation service upon the sand within our 3D model we build windows through the Jackson formation that expose the underlying in the sand in several places.

330
00:44:05.930 --> 00:44:19.310
Randy Kath: One of the larger windows measuring at a link up to 10 kilometers of the memphis and is a regional officer researchers wanted to verify map for wisdoms that may allow infiltration of service.

331
00:44:21.290 --> 00:44:36.260
Randy Kath: Using art seeing a 3D visualization of the strategy rapid sequence to water down was created and a vertical exaggeration to keep supplying to create the model, the raster of these balls in service, as well as the 10 meters by 10 meters.

332
00:44:37.400 --> 00:44:41.300
Randy Kath: For each converted to try and do it in your regular network so.

333
00:44:42.710 --> 00:44:47.450
Randy Kath: How many polygons for the unexpected services to create three blocks of.

334
00:44:48.860 --> 00:44:52.400
Randy Kath: The service geology maps for that service elevation draped over the.

335
00:44:53.690 --> 00:45:00.470
Randy Kath: falls for extruded between the top of the EC alien G walk through the bottom of the changes.

336
00:45:01.520 --> 00:45:09.650
Randy Kath: These images show the 3D model into perspective or west and south and north right we're looking for west to.

337
00:45:11.420 --> 00:45:23.420
Randy Kath: The completion of the geological model seismic hazard naturally generated he's managed to probabilistic hundred packs with the ground motions shall have a 5% 50 you're probably be seeing.

338
00:45:23.960 --> 00:45:36.230
Randy Kath: These maps cover two periods, point two seconds and one second one, second one, second round motion maps relate to because or the one that you story and 10 story, though, in respect to.

339
00:45:37.460 --> 00:45:45.950
Randy Kath: The background other campus and current usgs how's your maps used in building codes and having uniform geology which is not present in Washington DC.

340
00:45:47.870 --> 00:45:58.760
Randy Kath: Has the housing and urban development project perhaps considerable geology there is a notable difference, the results of the habitat Spain during the study compared to the rest yes.

341
00:46:00.200 --> 00:46:10.910
Randy Kath: I sure periods China Point two seconds mouth effective local geology is to reduce ground shaking hands about 70% of long periods shoving the one side.

342
00:46:11.960 --> 00:46:23.330
Randy Kath: effect of local geology is to increase ground shaking has in fact 52% however liquefaction hazard in the woodlands as high emotion short period shaky.

343
00:46:25.820 --> 00:46:28.460
Randy Kath: Thank you all and that concludes my presentation.

344
00:46:30.320 --> 00:46:31.280
Randy Kath: hazards of water.

345
00:46:37.100 --> 00:46:39.770
Randy Kath: Thank you Valerie does anyone have any questions for Valerie.

346
00:46:53.990 --> 00:46:55.490
Randy Kath: No questions at all.

347
00:46:56.450 --> 00:47:01.340
Valarie Harrison: I thought for sure, with all the usgs folks here that i'd get some questions about the hazard maps.

348
00:47:02.150 --> 00:47:03.350
Randy Kath: yeah so.

349
00:47:06.200 --> 00:47:16.280
Randy Kath: I just I just think it's fascinating personally what we're doing you know part of this session is to look at mapping techniques and doing 3D.

350
00:47:16.850 --> 00:47:31.340
Randy Kath: Because I personally think that we're we have the technology now where we don't have to do two dimensional sheets of paper anymore for geologic maps and seismic hazards, but we have the capability for three dimensional so it's a great technique that you're applying here.

351
00:47:32.180 --> 00:47:39.140
Valarie Harrison: yeah it's been really interesting i'm a master student at the University of memphis and i've been working on this project for about a year.

352
00:47:39.890 --> 00:47:55.040
Valarie Harrison: And it's been a great experience learning how to make these 3D models and i'd like to learn some new software to to see you know to compare right now i'm using Arc map and art scene.

353
00:47:56.300 --> 00:48:00.920
Valarie Harrison: But if anybody has any suggestions of other 3D modeling software that'd be great.

354
00:48:04.970 --> 00:48:12.290
Randy Kath: Well, I know, for all the students who are probably what looking at the presentations here, you know structure contour maps are so critical.

355
00:48:13.250 --> 00:48:27.440
Randy Kath: I don't use art map I use autodesk products civil 3D and surfer is really nice I don't know if you've used surfer at all so we're doing surfaces and that's kind of what I work with those two products.

356
00:48:29.810 --> 00:48:39.080
Valarie Harrison: yeah i've used surfer and i've played around with with the Q GIs but i'm looking for some stuff to do 3D modeling and particularly.

357
00:48:40.250 --> 00:48:43.760
Valarie Harrison: The cross section, you know a good cross section software.

358
00:48:43.910 --> 00:48:49.820
Randy Kath: yeah I know there are a couple of pieces of software out there, I think leap frog is one of them.

359
00:48:50.390 --> 00:49:03.020
Randy Kath: And vulcan is another one, but leap frog is more geologic I think vulcan is more designed for the mining industry, but both of those work pretty well i've worked with some clients who have worked with both of those products and they seem to like them.

360
00:49:04.190 --> 00:49:04.550
Randy Kath: Okay.

361
00:49:05.870 --> 00:49:06.500
yeah Thank you.

362
00:49:09.800 --> 00:49:11.960
Randy Kath: Okay, any other questions for Valerie.

363
00:49:18.890 --> 00:49:22.430
Randy Kath: Wait just another minute and then we'll get beth going at it.

364
00:49:53.570 --> 00:49:28.000
Randy Kath: Okay, I think we can go ahead and move forward our next presentation volcanoes to glaciers that's quite a range neoproterozoic riff basins in a paleozoic origin Southwest Virginia.

365
00:49:28.001 --> 00:49:42.980
Randy Kath: Okay, I think we can go ahead and move forward our next presentation volcanoes to glaciers that's quite a range neoproterozoic riff basins in a paleozoic origin Southwest Virginia.

366
00:49:44.330 --> 00:49:50.330
Randy Kath: Elizabeth mckay mcclellan and Tyler Rhea and beth will be presenting today.

367
00:50:00.500 --> 00:50:13.280
Randy Kath: hi and then along with mosquito Tyler Ray from Radford University in Radford Virginia, they need a greater so like snowball aren't glaciations constituted the most insurance facial period.

368
00:50:14.750 --> 00:50:27.260
Randy Kath: And it was frozen from the polls to the equator the most extensive record of neoproterozoic glaciation in the eastern us it sounded a blue ranger Southwest Virginia in the car foundation.

369
00:50:28.100 --> 00:50:36.200
Randy Kath: The kind of rock has been sitting to represent so baller deposits, but that assumption has been made a little knowledge of the actual beach.

370
00:50:37.190 --> 00:50:46.100
Randy Kath: kind of deposits Sharon ruin the map over live by moving won't kick rocks are the largest formation sharing shades of pink and red on the map.

371
00:50:46.610 --> 00:51:03.350
Randy Kath: Which form you're an initial recording of the supercontinent of redeeming the glacial strata include with new layer but stone though resembles are deposits and contains drop stones, as well as NASA dynamic type or glacial chill pockets.

372
00:51:04.790 --> 00:51:12.380
Randy Kath: In this presentation we'd like to explore for particular questions about the contract and it's possible relationships to have our.

373
00:51:13.280 --> 00:51:28.310
Randy Kath: First, has the kind of rock into the chronology of we have brothers, or it goes us to major glaciations disturbance search certain and there are no one if I instead of all earth and the cryo June period of the year, so it.

374
00:51:29.330 --> 00:51:38.600
Randy Kath: Until recently, the age of the Rock was only thing standing by the underlying all candidates and the overlying he macklin to camera and show how it.

375
00:51:40.250 --> 00:51:50.030
Randy Kath: In the senior from a recent paper by Paul hawken one of the world's experts and snowball earth to kind of rock is depicted foreign journalists 30 relations theory.

376
00:51:51.680 --> 00:52:00.410
Randy Kath: Although the con rock sedimentary deposits can't be directly dated and that remains in bracket are the underlying right, so the Mount Rogers.

377
00:52:01.070 --> 00:52:13.910
Randy Kath: Which range in age from 739 78 years but to rush out of the usgs map right outliers which are interpreted as close within the camera.

378
00:52:14.510 --> 00:52:27.230
Randy Kath: And recently reported ages around 71 to 72 million years from these bodies if correct this clearly indicates the Colorado must be too old to perform during study hall or.

379
00:52:28.970 --> 00:52:46.850
Randy Kath: The contact between the Colorado and matt Rogers on Asian appears to be formal in this study here the relationship cri lights within the car differ slightly commercial area, however, on the map the pale pink bright light unit in contact the corner rock include.

380
00:52:47.930 --> 00:52:56.180
Randy Kath: These, but these volcanic rocks very much resemble and our long strike that the slightly older white top number of now.

381
00:52:57.860 --> 00:53:06.020
Randy Kath: On the other hand, the shining dart team consists of plastic box they do appear to enter finger with glacial box.

382
00:53:06.860 --> 00:53:20.240
Randy Kath: And the week, like in several highlights samples free rein were dating a shown by those stories on now, and those analyses reading problems that was look closely at the location picked up by the yellow star.

383
00:53:23.000 --> 00:53:40.190
Randy Kath: Yes, there are complications to decide bring the exact relationship between the counter rock and the one candidates and our seminary but there's who shown here are the three model produced by a drone skin of a highly whether the very instructive run cut through the band classes.

384
00:53:41.480 --> 00:53:52.820
Randy Kath: In the West end of the types of to your ride non world in touch your credit by via violated by and large painting diagram of the area that didn't scan well.

385
00:53:53.840 --> 00:54:02.300
Randy Kath: The time Sir overlaying by course our case, they can tell us the dice and true the artist, as well as the bagel milestones and the camera.

386
00:54:03.380 --> 00:54:10.100
Randy Kath: We sampled of lc night show here, could you chronology as it may be the unmistakable lock in this area.

387
00:54:11.270 --> 00:54:24.830
Randy Kath: So instead of fun conclusion offer I offices it's got to be tested further our female relationships indicate that the class you sequence innovation kind of operation settlements our code evil.

388
00:54:25.760 --> 00:54:30.140
Randy Kath: However, the older white highlight doesn't fit neatly into this feature.

389
00:54:31.100 --> 00:54:48.200
Randy Kath: That taken into account the environment of the active partner looking at this time it's possible that the relational empire classic deposits were filling in with patients are the the top I lighted up looted in the football of the base and down the halls.

390
00:54:49.370 --> 00:55:00.140
Randy Kath: summaries is leaving Iraq and snowball earth well reporting ages due to indicate that cannot glacial closets are too old for injuries know all events.

391
00:55:00.920 --> 00:55:13.340
Randy Kath: But we have been determining the agent llc is the state or closely bracket the age of the days of deposits on rock and that's the onset of glaciation more secure, thank you.

392
00:55:16.100 --> 00:55:21.350
Randy Kath: hey Thank you beth very interesting presentation does anyone have any questions for beth.

393
00:55:33.260 --> 00:55:34.910
Randy Kath: Okay, yes please um.

394
00:55:34.940 --> 00:55:38.690
Valarie Harrison: yeah did you run into any complications using the drone footage.

395
00:55:40.490 --> 00:55:57.140
Beth McClellan: Yes, yes, that was one of our first attempts at doing outcrop studies, with the drones we have a quite a few here in our department at Radford and our students are really getting pretty good with them.

396
00:55:58.190 --> 00:56:06.200
Beth McClellan: And, but the problem was it, it seemed like those, especially the may fake dykes that were really highly weathered.

397
00:56:07.250 --> 00:56:12.770
Beth McClellan: We just couldn't get them imaged at all for some reason.

398
00:56:14.270 --> 00:56:27.260
Beth McClellan: We were using PICs for the for the 3D image and even went back and re flew the the outcrop and still didn't turn out very well so lots to learn.

399
00:56:29.540 --> 00:56:37.490
Valarie Harrison: yeah there are a lot of fun to fly i've been curious about using them for geologic mapping like that so it's very interesting, thank you.

400
00:56:39.290 --> 00:56:52.340
Beth McClellan: Yes, we're doing that quite a bit here at read through dog, both for mapping and slope stability studies and that sort of thing so imaging outcrops and making 3D models that you can actually.

401
00:56:53.510 --> 00:57:00.650
Beth McClellan: gather structural data from without having to measure everything with a Brenton.

402
00:57:03.980 --> 00:57:14.240
Randy Kath: hey matt this Randy and we've been doing a lot of modeling to with drones and looking at some of the Rock towns and rock cities up in the pennsylvanians photography.

403
00:57:15.230 --> 00:57:28.010
Randy Kath: And the biggest problem we have of course is tree cover and along this outcrop, but I would assume you didn't have much tree cover so what's causing the holes the black holes, you have any idea.

404
00:57:28.490 --> 00:57:41.480
Beth McClellan: Well, I I still don't know for sure there's not much tree cover on the APP itself, it was recently scraped along this gravel road I think they tried to widen the road there.

405
00:57:41.960 --> 00:57:52.310
Beth McClellan: And it's a falling apart, unfortunately, there are trees, right at the top of the outcrop and um let's see that's going to think.

406
00:57:53.360 --> 00:57:55.340
Beth McClellan: They were blocking the sunlight.

407
00:57:56.390 --> 00:58:07.190
Beth McClellan: You know it's pretty much blocking the sunlight all day long on that outcrop, and so I don't know if that was a problem or not just getting good images, especially toward the top a outcrop.

408
00:58:10.280 --> 00:58:23.090
Randy Kath: You know, when we were putting in the sand rob period, we had the fly cerebral flight lines, because of the shadows of the trees and in those pennsylvanian rocks we had a lot of deep.

409
00:58:24.290 --> 00:58:33.380
Randy Kath: In a weather joints in the shadows down there the when we put when we process, the data it didn't know what to do with those shadows and we had these huge voids and.

410
00:58:33.890 --> 00:58:41.000
Randy Kath: When you rotate in 3D they were their massive canyons and they were just fractures so we had a little bit of trouble with that.

411
00:58:42.230 --> 00:58:43.580
Beth McClellan: yeah that is a problem.

412
00:58:44.210 --> 00:58:48.380
Beth McClellan: yeah we just recently gotten a heavy lift her own and allied arguments.

413
00:58:49.880 --> 00:58:55.340
Beth McClellan: And of course the light dark and kind of take out the vegetation so we're looking forward to getting that going.

414
00:58:56.390 --> 00:59:14.600
Randy Kath: yeah that'll be great these are these tools that we have down for doing mapping and and doing imagery and 3D scans and detailed topography, where we can see very small features on the ground is just I think it's spectacular it's really advanced in our mapping techniques.

415
00:59:15.710 --> 00:59:17.150
Beth McClellan: Absolutely yeah.

416
00:59:18.740 --> 00:59:21.650
Randy Kath: anybody else have any questions any further questions for math.

417
00:59:23.120 --> 00:59:24.800
mark carter: I have one hey Baptist more.

418
00:59:26.810 --> 00:59:38.000
mark carter: i've kept it a little late, because I was at another session so if the white top is a little too old for snow bar to how what would be the what would be the classic age, if you will, to get that.

419
00:59:39.050 --> 00:59:42.680
mark carter: For snowball earth and how far or are you all.

420
00:59:44.180 --> 01:00:04.910
Beth McClellan: So the Sturdy, one which is the main metamorphic excuse me thinking metamorphosis the main glaciation that marks the cry virginian period now is starts at 717 million years so we're will Wilson south of that I guess you could say.

421
01:00:06.710 --> 01:00:18.500
Beth McClellan: yeah we're talking around 750 and of course Arthur has gotten these new ages now 751 to 752, on the other rights so looks like we're too old.

422
01:00:19.970 --> 01:00:20.900
mark carter: Right, what would you.

423
01:00:22.040 --> 01:00:25.640
mark carter: Do with Alpine glaciers that will feed into the system.

424
01:00:26.840 --> 01:00:37.730
Beth McClellan: um yeah i'll probably sell I mean they're pretty localized, at least in terms of plex exposed or what's what we have you no evidence for anymore.

425
01:00:38.300 --> 01:00:50.390
Beth McClellan: I know that in central Virginia northern Virginia, there are some that some glacial deposits that are thought to be younger and I some that i'm chuck Bailey and those people who worked on.

426
01:00:53.030 --> 01:00:57.710
Randy Kath: It we should probably move on thanks beth a very interesting presentation.

427
01:00:59.450 --> 01:01:08.420
Randy Kath: I next presentation is the geologic map of the leesburg and declined greenbrier county West Virginia and Sarah baldwin but will be presenting.

428
01:01:17.480 --> 01:01:27.230
Randy Kath: Hello everyone i'm Sarah baldwin charleston southern University in charleston South Carolina thanks for coming today.

429
01:01:29.750 --> 01:01:30.620
Randy Kath: If you would like.

430
01:01:31.010 --> 01:01:43.370
Randy Kath: Please expand the video window, so you can see my slides word clearly the title of my poster is a geologic map of the wind Fergana Klein greenberg county West Virginia.

431
01:01:46.910 --> 01:02:05.630
Randy Kath: This slide shows a little index map of the area and white and Gray, is where the mississippian green bar group is exposed it's about 800 feet of very shoreline stones, although you are surely units.

432
01:02:07.730 --> 01:02:19.490
Randy Kath: It is under lane by the Mississippi and mcrae formation, which is shown in yellow on the map and overlaid by this in one chunk formations.

433
01:02:20.000 --> 01:02:40.340
Randy Kath: Which is shown in pink on the map the area to the left the winds Fergana climb that banana thing is has never been mapped in a detailed way so that was the focus of this study, which was supported by the cave conservancy of Virginia.

434
01:02:42.650 --> 01:02:55.700
Randy Kath: here's a strata graphic column of the limestone showing the names of units i'm at to the individual units and their structures and this is the final version of the map.

435
01:02:57.590 --> 01:03:13.370
Randy Kath: interstate 64 runs right through the middle the northern edge is covered by some thick gravel opium and williamsburg sits up there on the North side, all of a sudden West Virginia sit down on the southern edge.

436
01:03:14.420 --> 01:03:25.370
Randy Kath: Of the Mississippi the green bar group is shown in green very shades of green in the upper most unit, the alderson the shonan sort of a chocolate Brown.

437
01:03:26.300 --> 01:03:49.970
Randy Kath: The credit information is kind of a rust light brown color and you can even see on the lidar here that the green limbs of the decline, make a deep cars Valley, which is full of springs caves sinking strains.

438
01:03:52.730 --> 01:03:54.200
Randy Kath: and other course features.

439
01:03:57.320 --> 01:04:08.600
Randy Kath: One of the big surprises of this study, which is in the appalachian plateau was the discovery of very large extensive reverse falls through this and client both lens.

440
01:04:09.260 --> 01:04:22.520
Randy Kath: These reverse faults are up to 20 miles long they have some of them have 6800 feet of displacement on them and they did to the southeast so they showed up.

441
01:04:23.510 --> 01:04:39.290
Randy Kath: On lidar they were one was identified by price in heck in 1939 several small ones were identified by my PhD thesis that's me Heller 1980 in the valley, the lewisburg Valley, to the east.

442
01:04:39.680 --> 01:04:56.150
Randy Kath: But I was able to find these, especially on lidar which was provided by Dan Dr the US geological survey and they're recognizable by steeply different layers in this place, so the default zone is that red line.

443
01:04:57.200 --> 01:05:03.590
Randy Kath: there's lower green bar lunch down on top of the mcrae shelf dipping gently to the West.

444
01:05:05.090 --> 01:05:16.970
Randy Kath: The beds are shredded and vertical right their peers she's no fault zone and then to the left of that is occur greenberg group the older son and union and lily Dale shale.

445
01:05:17.810 --> 01:05:28.970
Randy Kath: of lower my chunk and here's a cross section showing a sketch of the structures with two large cave which are also included in this.

446
01:05:29.990 --> 01:05:33.920
Randy Kath: resurgence is pierce's mill cave and pure seascape.

447
01:05:36.620 --> 01:05:42.380
Randy Kath: Some of the reverse faults were identifiable by aligned and cold shed in this picture.

448
01:05:43.430 --> 01:05:54.050
Randy Kath: The yellow line is the raiders valley fault zone, there was major displacement on that and minor displacement on the pink and the yellow or pink in the green sorry.

449
01:05:55.760 --> 01:06:16.250
Randy Kath: Just to the south of those aligned sinkholes culberson pre cuts across that area, and there are some really cute right folds of visible on the lidar shown by the arrows in this slide and the pink line is the mccready here the units are all the Bank to the east rather steeply.

450
01:06:18.230 --> 01:06:37.310
Randy Kath: In the field, the finance world were visible, because the rocks were shredding so I have a photograph of that I usually it was the PIC way in the tiger that were involved in this, because they're more shelley and therefore more ductile.

451
01:06:38.660 --> 01:06:50.840
Randy Kath: Also, you can see slick insides and some places along the faults and where the rocks have been stretched there were big cows leg veins shown in this last photo.

452
01:06:54.110 --> 01:07:04.280
Randy Kath: I would like to thank the cake conservancy of the virginia's for their grants port West Virginia association of case studies for the use of their field house.

453
01:07:04.700 --> 01:07:16.370
Randy Kath: Dan doctor who provided the lidar images Paula hunt who compiled the final map and my field assistance margaret's last and Jennifer merrick Thank you.

454
01:07:19.520 --> 01:07:33.650
Randy Kath: Well, thank you, Sarah and I apologize on the slides they weren't sync so we toward the end there got a manual Sarah if you'd like me to go back to one of the slides in any particular one we've got about three to four minutes.

455
01:07:36.920 --> 01:07:40.910
Sara Baldwin: The main map would be good, the one that's title just geologic map yeah.

456
01:07:41.660 --> 01:07:42.170
Randy Kath: There you go.

457
01:07:42.680 --> 01:07:45.020
Sara Baldwin: I synced um I don't know what happened.

458
01:07:46.940 --> 01:07:57.920
Randy Kath: yeah that's okay I just I saw manually there and I was texting chatting with GSA and they thought they weren't seeing, but then I thought, well, maybe I can do it manually so.

459
01:07:58.100 --> 01:07:58.940
Sara Baldwin: He did a great job.

460
01:07:59.360 --> 01:08:01.460
Randy Kath: that's coming in, while they're good to find them but.

461
01:08:01.460 --> 01:08:02.240
tabitha.

462
01:08:07.250 --> 01:08:09.020
Randy Kath: Does anybody have questions for Sarah.

463
01:08:19.670 --> 01:08:22.190
Randy Kath: That all this technology here so.

464
01:08:28.430 --> 01:08:36.500
Beth McClellan: I Sarah a question i'm just interested in your term terminology shredded rock So where does that come from.

465
01:08:38.810 --> 01:08:46.880
Sara Baldwin: I I should use the word cleavage I guess would be better, but it's just something that occurred to me.

466
01:08:48.830 --> 01:08:50.420
Beth McClellan: look pretty shredded right.

467
01:08:57.170 --> 01:08:58.520
Randy Kath: I guess a great new term.

468
01:09:04.040 --> 01:09:04.280
Sara Baldwin: Was.

469
01:09:04.340 --> 01:09:05.900
Sara Baldwin: Really striking when I can hop.

470
01:09:11.480 --> 01:09:12.650
Randy Kath: On your insides.

471
01:09:13.760 --> 01:09:15.920
Randy Kath: Are you in a sheer zone here.

472
01:09:16.250 --> 01:09:17.090
Sara Baldwin: Yes, yes.

473
01:09:17.510 --> 01:09:28.160
Sara Baldwin: Okay, this year's on was probably 100 feet wide in that particular spot it's exposed well on us highway 12 which goes right through that area.

474
01:09:30.110 --> 01:09:30.830
Randy Kath: very nice.

475
01:09:37.580 --> 01:09:43.070
Randy Kath: The last the poster if it doesn't haven't seen at least I know how to get the slides of now so on.

476
01:09:44.360 --> 01:09:59.540
Randy Kath: Okay we'll go on to the next presentation, and this is lidar base mapping of landslides along the cusp of this river Washington revealing regional structure and volcanic hazards Isaac Pope will be presenting.

477
01:10:07.190 --> 01:10:11.120
Isaac Pope: hello, may I share my screen, I will upload a.

478
01:10:11.150 --> 01:10:12.560
Randy Kath: Video for them.

479
01:10:12.590 --> 01:10:15.110
Randy Kath: yeah feel free to share your screen.

480
01:10:18.500 --> 01:10:18.860
Isaac Pope: Okay.

481
01:10:23.300 --> 01:10:24.230
Isaac Pope: All right, well.

482
01:10:24.290 --> 01:10:24.920
Randy Kath: Thank you all.

483
01:10:26.210 --> 01:10:27.140
Randy Kath: I can say that's okay.

484
01:10:27.980 --> 01:10:28.670
Isaac Pope: We can just.

485
01:10:30.860 --> 01:10:31.640
Isaac Pope: Okay, all right.

486
01:10:33.710 --> 01:10:36.140
Isaac Pope: Thank you, I was just going to share my poster anyways.

487
01:10:38.240 --> 01:10:46.910
Isaac Pope: Alright, well, thank you very much i'm a 17 year old freshman undergraduate students esoteric college and Western Washington.

488
01:10:47.930 --> 01:10:56.540
Isaac Pope: And i've been very interested in the unusual relationship between landslides and Alice volcanism here in Southwest Washington.

489
01:10:57.950 --> 01:11:18.560
Isaac Pope: So this this this river flows from a good rocks volcanic field and actually goes in through the triangle formed by mount Adams, to the south east St Helens the southwest and matter near to the north, as you can see, in a little bit and figure one here at the bottom.

490
01:11:20.540 --> 01:11:25.640
Isaac Pope: One of the interesting things about the sisters river drainage is, although it fuels have.

491
01:11:26.900 --> 01:11:36.290
Isaac Pope: A rich a forestry industry, and it has a this close relation to all the cascade volcanic there hasn't been a whole lot of hazard mapping in this area.

492
01:11:37.520 --> 01:11:42.290
Isaac Pope: Even though we see it has been closely linked to a cascade volcanism general.

493
01:11:43.790 --> 01:11:49.850
Isaac Pope: exposed longest river during our leasing museum volcanic.

494
01:11:51.260 --> 01:12:08.540
Isaac Pope: And what kind of classics from the early cascade magnetism and, more recently, we have seen lava flows from Adams within the past 500,000 years flow down into the systems river and a number of glaciations, but most of the most.

495
01:12:09.680 --> 01:12:18.890
Isaac Pope: predominantly most of the activity is supposed to happen along systems river supposed to be glacial origin early researchers along the sisters river thought that.

496
01:12:21.710 --> 01:12:32.060
Isaac Pope: the depth of show terraces along the syllabus river resulted from glacial out wash during the Evans creek glaciation about 20,000 15,000 years ago.

497
01:12:34.190 --> 01:12:36.050
Isaac Pope: But what we find is.

498
01:12:37.370 --> 01:12:37.760
Isaac Pope: My.

499
01:12:38.840 --> 01:12:45.080
Isaac Pope: my previous project on this area was studying these quarterly sort of tears deposits and.

500
01:12:46.520 --> 01:12:59.000
Isaac Pope: We find invocation and number of other features that is indicative of debrief lows, and this is supported by large boulders up to several meters across that are found.

501
01:12:59.420 --> 01:13:10.730
Isaac Pope: Within the terraces or overlying the terraces and, since these take terraces cannot be formed directly by glaciers, and the borders themselves are too large for glacial out wash.

502
01:13:12.560 --> 01:13:28.490
Isaac Pope: And that's all the terraces or correlate to each other, then it is more likely that a large debris flow or alohar from now Adams within the last 6000 years ago, two years ago, after the.

503
01:13:29.810 --> 01:13:30.980
Isaac Pope: Evans great glaciation.

504
01:13:32.660 --> 01:13:47.270
Isaac Pope: And we can also see a number of features such as during the central area along the lidar neck, there are some taller strength terraces up to 3334 meters above the system is river and etched into those are.

505
01:13:48.230 --> 01:13:56.780
Isaac Pope: NASA mostly channels which shows a very erosive of the heart and so it's all these terrorists supposed to have formed at the same time being.

506
01:13:57.050 --> 01:14:06.230
Isaac Pope: formed within the same event, we can then use it as a time scribe graphic indicator to compare the landslides in this area so using lidar I then mapped.

507
01:14:06.860 --> 01:14:17.510
Isaac Pope: These lands is based on their relation to overlying the terraces or being truncated by the deposits within those terraces the Greenland slides posted the syllabus lar from Adams.

508
01:14:18.050 --> 01:14:32.330
Isaac Pope: yellow ones predate are the red ones are of unknown relation to the heart, but what we find is that the flows are sorry the landslides after the heart can be much larger.

509
01:14:33.020 --> 01:14:47.690
Isaac Pope: than the ones previous, but they also have a wider distribution there's two population centers the larger ones, the smaller ones, well before the heart, we see a highly eroded one sometimes they're only scarves and other cases they have later been renegotiated.

510
01:14:49.160 --> 01:14:53.300
Isaac Pope: But we see that this this was harvest likely have fairly erosive.

511
01:14:54.500 --> 01:14:57.080
Isaac Pope: which has really triggered some of these landslides, which.

512
01:15:00.710 --> 01:15:03.080
Isaac Pope: They asked her hazards.

513
01:15:04.220 --> 01:15:14.300
Isaac Pope: But what we can also see is comparing these landslides to other regional structures, like pseudo carts that formed most likely during museum folding.

514
01:15:15.350 --> 01:15:16.820
Isaac Pope: associated the cascadia.

515
01:15:18.170 --> 01:15:29.000
Isaac Pope: subduction zone, we can then use these land sites to map regional falls, and then by finding a more closely the regional structure, we can then predict.

516
01:15:30.080 --> 01:15:35.510
Isaac Pope: Where high risk Lopes may be or more unstable slopes.

517
01:15:36.530 --> 01:15:38.510
Isaac Pope: which I hope to do in further research.

518
01:15:40.550 --> 01:15:46.010
Isaac Pope: Thank you very much for your attention today, I very much welcome any suggestions or comments you may have on this research.

519
01:15:49.940 --> 01:15:52.760
Randy Kath: I was a great job I really appreciate the.

520
01:15:54.110 --> 01:16:05.540
Randy Kath: You and I know when you first contacted me about presenting this I thought this is a great forum to present this information, even those out in Washington, I think a lot of us learn.

521
01:16:06.620 --> 01:16:10.490
Randy Kath: learn the details of how we can use lidar and other.

522
01:16:11.000 --> 01:16:14.270
Randy Kath: techniques for determining geologic.

523
01:16:14.270 --> 01:16:18.440
Randy Kath: structures and getting your cross cutting relations in your age relationships that you've.

524
01:16:18.440 --> 01:16:19.010
Randy Kath: shown here.

525
01:16:21.770 --> 01:16:23.360
Randy Kath: Does anybody have any questions for Isaac.

526
01:16:24.290 --> 01:16:24.890
Isaac Pope: Thank you.

527
01:16:30.050 --> 01:16:35.480
Randy Kath: still have about four minutes here so very interesting.

528
01:16:47.240 --> 01:16:41.000
Randy Kath: So make McKinsey are you on with us.
