WEBVTT 1 00:00:00.001 --> 00:00:14.640 Laura Mulrooney: Okay y'all we're going to go ahead and get started um if you would like to turn your cameras on me encourage you to just so it can feel a little bit more like a real field trip and let's let's get started with a man right let's get to know each other. 2 00:00:17.910 --> 00:00:25.830 Laura Mulrooney: So we'll introduce ourselves first and then we'd like other people to introduce themselves to just so that we can get to know we're going to do some group activities. 3 00:00:26.580 --> 00:00:34.770 Laura Mulrooney: So hopefully we can get meet each other, a little bit so hi i'm Laura and i'm an undergrad at the University of Florida i'm a senior. 4 00:00:36.150 --> 00:00:45.660 Laura Mulrooney: hey guys i'm Emily i'm also a senior at the University of Florida i'm Jamie i'm a junior at us and i'm tori and i'm a senior at us. 5 00:00:47.250 --> 00:00:54.270 Laura Mulrooney: yeah so do we just want to go through, and people that are there, we can start with a Dr Marshall do you want to introduce yourself. 6 00:00:55.200 --> 00:01:00.630 Anita Marshall: hey everybody, my name is Nina Marshall i'm a lecturer at us. 7 00:01:03.300 --> 00:01:04.740 Laura Mulrooney: Derek do you want to introduce yourself. 8 00:01:06.090 --> 00:01:09.900 Derek Thorn: Sure i'm Derek form i'm a graduate from college. 9 00:01:12.870 --> 00:01:14.400 Laura Mulrooney: machida you want to introduce yourself. 10 00:01:16.380 --> 00:01:24.210 Nikita Kepezhinkas: hi everyone I am akita i'm a graduate student at the University of Alberta in Canada former graduate of the University of Florida. 11 00:01:28.530 --> 00:01:30.330 Laura Mulrooney: sands, or do you want to introduce yourself. 12 00:01:30.540 --> 00:01:36.060 Sandor Ricketts: hi sandor recently read it from auburn university just wanted to check out, you have to offer. 13 00:01:38.010 --> 00:01:43.770 Laura Mulrooney: yeah um and hazel or Dan i'm not sure if you're there if you would like to introduce yourself that would go right ahead. 14 00:01:44.400 --> 00:01:49.020 Hazel Gordon: i'm hazel and i'm very old and I haven't comb my hair and I don't want to show my face. 15 00:01:50.790 --> 00:01:56.760 Hazel Gordon: And I don't know very much about the value of your area so i'm that's why i'm here thanks for having this. 16 00:01:57.600 --> 00:01:58.320 Laura Mulrooney: Of course. 17 00:01:59.490 --> 00:02:02.820 Laura Mulrooney: And Dan if you're there to feel free to introduce yourself. 18 00:02:06.660 --> 00:02:15.900 Laura Mulrooney: Okay, well, the first thing that we're going to do is we're going to start with some little bit of a drawing exercise just to get our field skills going the goal of this trip. 19 00:02:16.500 --> 00:02:25.170 Laura Mulrooney: is to have it as an introduction for field work, for it was designed for undergrads but for anyone who'd like to build their field skills. 20 00:02:27.120 --> 00:02:28.800 Laura Mulrooney: See what's the chat to. 21 00:02:31.020 --> 00:02:34.590 Laura Mulrooney: Okay, so we're going to start i'll share my screen. 22 00:02:40.380 --> 00:02:49.230 Laura Mulrooney: So we're going to start by drawing and we're going to sketch with you and we're just going to all work on our field skills we're going to have a few different activities and we are going to do some group ones coming up, but we just want to. 23 00:02:49.770 --> 00:02:52.230 Laura Mulrooney: Get the creative juices flowing on this early morning. 24 00:02:53.730 --> 00:03:02.400 Laura Mulrooney: So we're going to start by sketching in your notebook or a piece of paper or a whiteboard whatever you have nearby on what you see over here to the left. 25 00:03:04.560 --> 00:03:11.370 Laura Mulrooney: Obviously there are certainly there are only so much you can observe from a picture, but try to just see what you've noticed there. 26 00:03:11.970 --> 00:03:28.800 Laura Mulrooney: write it down draw you can put some labels if you'd like to and then we'll talk about and we'll we'll share what we draw as well i'm just to see see what we all come up with, so we will give we'll start with seven minutes drawing this. 27 00:03:29.970 --> 00:03:41.580 Anita Marshall: Laura what kind of things should we draw I mean there's a lot going on here there's roots there soil there's geology how much like what should we be drawing. 28 00:03:42.240 --> 00:03:54.630 Laura Mulrooney: yeah, so I would focus on you want to make sure that you draw a complete sketch, so that if you were going to look back at your notes later, you would know what you were trying to draw I would focus on some of the geologic features. 29 00:03:55.920 --> 00:04:08.370 Laura Mulrooney: or anything that might be important, so noticing where the roots are if they're all in one layer that would be important if you notice any sedimentary structures that would be important and I try not to forget a scale to that also would be good. 30 00:04:10.080 --> 00:04:11.040 Anita Marshall: Great thanks. 31 00:04:11.490 --> 00:04:11.940 Laura Mulrooney: yeah. 32 00:04:12.180 --> 00:04:13.080 Anita Marshall: Who is helping. 33 00:04:14.190 --> 00:04:15.780 Laura Mulrooney: I see welcome. 34 00:04:17.370 --> 00:04:18.060 Anita Marshall: This is like. 35 00:04:20.730 --> 00:04:22.140 Laura Mulrooney: hey so we're all going to sketch. 36 00:04:57.810 --> 00:04:24.000 Sandor Ricketts: Switching screens. 37 00:04:24.001 --> 00:04:53.390 Laura Mulrooney: Okay yo so I know that it's probably not been quite enough time but let's go ahead and see what you have just so that we can talk to you this and we'll also try to add a little bit of context um so I guess, we can start by showing some of ours and we do you want to show. 38 00:04:55.850 --> 00:05:00.620 Laura Mulrooney: So let's see this is what Emily drew for hers. 39 00:05:01.430 --> 00:05:09.770 Laura Mulrooney: And so, some i'll point out some of the things that she has here so first at the top of the page she both wrote the STOP we're at which we didn't explicitly say that this is black rock beach. 40 00:05:10.250 --> 00:05:18.530 Laura Mulrooney: If you had a chance to look at those before you came which wasn't a requirement, this is one of the thoughts that we had published she also then wrote the date and approximate time. 41 00:05:19.940 --> 00:05:31.760 Laura Mulrooney: And then she went through here, and she put a scale bar on the side and then she also she gets the things that showed up up to her so there's a little bit of a white layer she saw she gets the roots a little bit of a yellow layer 42 00:05:32.390 --> 00:05:41.600 Laura Mulrooney: And then the the brown is black layer which has our home instructions, but she been labeled what she drew there, and she also then put numbers by the sides which. 43 00:05:42.740 --> 00:05:53.240 Laura Mulrooney: would be useful if we had been there in person and you could have actually written some descriptions which we'll talk about a little bit more um Jamie I guess two years to. 44 00:05:55.250 --> 00:06:09.230 Laura Mulrooney: So Jamie sketch hurts is a little bit different too, but, as you can see, it has the same kind of the same structures and you can show the different units with all using the same color to your hospital is possible. 45 00:06:11.510 --> 00:06:22.040 Laura Mulrooney: If any of y'all would like to show what you drew have feel free we'd love to see it, but if not, we can talk a little bit about what what we drew and what we noticed here in this outcrop to. 46 00:06:23.030 --> 00:06:30.710 Laura Mulrooney: um so we did have a question of what how lucky cross beds are so you have cross beds, which you know if you picture, like a ripple mark in the sand. 47 00:06:31.730 --> 00:06:36.800 Laura Mulrooney: What we typically think of as the Cross business, you have like a sit like a sigmoid shape like where you have. 48 00:06:37.220 --> 00:06:50.540 Laura Mulrooney: A slope that goes down um, but if you were to cut that perpendicular to that what you're actually going to see is like a hammock structure, and so, in many ways, this is a structure where, if you, you have your typical ripple mark if you were to cut it. 49 00:06:51.740 --> 00:06:58.340 Laura Mulrooney: In a way, that is not it's not the typical way that you see a structure which I think i've got pictures of this. 50 00:06:59.720 --> 00:07:09.830 Laura Mulrooney: So, if you look in the field guide, I think I have some sketches of trying to explain these um so it's the same thing as a ripple it's the same thing as a ripple mark just cutting a different orientation. 51 00:07:11.030 --> 00:07:17.780 Laura Mulrooney: Which that helps to tell us some if we noticed these on a beach face that helps to tell us a little bit about the current direction. 52 00:07:18.650 --> 00:07:26.090 Laura Mulrooney: For these, we didn't actually spend enough time to analyze if they're sloping a certain direction or not, but we know that the current had to be moving up. 53 00:07:27.980 --> 00:07:31.580 Laura Mulrooney: I guess within the wall not perpendicular to the wall that we're looking at. 54 00:07:34.850 --> 00:07:42.260 Laura Mulrooney: yeah it's anybody want to show us there's and we can offer some feedback if you'd like if not that's fine. 55 00:07:43.580 --> 00:08:05.120 Anita Marshall: I am a notoriously slow fields catcher because I never seem to get the details, the way I like them in the field, so what i'll often do is a really loose sketch with annotations and I just tell myself like where the different colors go and I just I literally just write it down. 56 00:08:05.150 --> 00:08:20.420 Anita Marshall: yeah other than sketches and then I fill in the details later when I have time to do it right, one of the challenging things on this outcrop driving me nuts, is how to indicate the sort of gradation of transition. 57 00:08:21.050 --> 00:08:30.860 Anita Marshall: Between the tan layer and the dark layer below if you just have a pencil right and you're just doing like stripling or shading you know how. 58 00:08:32.360 --> 00:08:32.870 Laura Mulrooney: Do you. 59 00:08:34.340 --> 00:08:40.010 Anita Marshall: You know, do that in a way that is makes any kind of sense, you know. 60 00:08:42.020 --> 00:08:46.310 Anita Marshall: it's always challenging for me until I can get back and like us colored pencils or something. 61 00:08:48.980 --> 00:08:49.430 Laura Mulrooney: Yes. 62 00:08:50.990 --> 00:08:52.700 Laura Mulrooney: And the key to do you want to show yours. 63 00:08:54.050 --> 00:08:58.010 Nikita Kepezhinkas: Absolutely i'm thinking right here, we all see. 64 00:08:59.630 --> 00:09:02.720 Nikita Kepezhinkas: Again, not very true to life just kind of. 65 00:09:03.920 --> 00:09:05.480 Nikita Kepezhinkas: Get the data get out. 66 00:09:07.280 --> 00:09:08.270 Laura Mulrooney: Sure what's important. 67 00:09:10.130 --> 00:09:17.450 Laura Mulrooney: Good yeah, and so I guess kind of like Dr Marshall mentioned, which is what Emily started to do by labeling the units is. 68 00:09:17.960 --> 00:09:24.170 Laura Mulrooney: If you were there, and you were actually able to make some observations of each of these units, you would want to write some sort of description. 69 00:09:24.560 --> 00:09:34.130 Laura Mulrooney: You would you could write that oh this top one is white and it has a certain brain size and it looks like it's mostly courts or something yeah like Nikita has there. 70 00:09:35.870 --> 00:09:39.050 Laura Mulrooney: Yes, and so you'd want to include that you want to make some real observations. 71 00:09:39.560 --> 00:09:54.020 Laura Mulrooney: exactly like that, and you can write that and that's to help clue you in later it's just everything to help jog your memory, so that when you're later, looking back at your notes trying to remember what you actually saw what was important that you can decide for your own your own notes. 72 00:09:55.760 --> 00:09:56.600 Hazel Gordon: I have a question. 73 00:09:57.290 --> 00:09:57.980 Anita Marshall: yeah go ahead. 74 00:09:58.520 --> 00:10:15.350 Hazel Gordon: I have a question I was wondering about the soil profile if anybody identify that and what kind of soil that might be it looks pretty well developed to me organic layer and olivia layer and so on, down to bedrock so Has anybody classified it. 75 00:10:16.910 --> 00:10:24.590 Laura Mulrooney: Not that I know of, so this is right on a beach like we were practically standing in the water, when we took this picture. 76 00:10:25.670 --> 00:10:35.690 Laura Mulrooney: We do know, from what we were taught that this area is on the North shore of a barrier island down in Florida, and so it's experienced. 77 00:10:36.590 --> 00:10:42.380 Laura Mulrooney: A lot of erosion in the very recent time period, and there are there are Paleo. 78 00:10:43.070 --> 00:10:58.820 Laura Mulrooney: Paleo souls throughout this area that we did note they're not shown in this picture, I think, but I think in some of our other videos we did talk about them and they're also our actual like mangroves on the beach itself, so this area was was a forest, not that long ago. 79 00:11:00.350 --> 00:11:01.070 Hazel Gordon: Okay, thanks. 80 00:11:03.950 --> 00:11:07.400 Laura Mulrooney: yeah um so we're going to have you all sketch one other thing. 81 00:11:07.940 --> 00:11:10.430 Laura Mulrooney: Just before we move on to something else. 82 00:11:13.190 --> 00:11:13.700 here. 83 00:11:30.980 --> 00:11:42.170 Laura Mulrooney: Just have you sketch this picture here to the left, this time just want to focus on your scales, a little bit different here and wanting to focus on what you've actually see here that stands out to you. 84 00:11:43.220 --> 00:11:48.860 Laura Mulrooney: um I would look at grain size, as well as if you can see any sort of composition. 85 00:11:50.240 --> 00:11:58.370 Laura Mulrooney: As well as just any features and then we'll once again will give a little bit more time, I guess, for this one will try to do around 10 minutes. 86 00:11:59.270 --> 00:12:08.000 Laura Mulrooney: Just to sketch this and see what stands out to you and then we'll we'll talk about it again and to give some context, this is in the St Augustine area, so this is once again right on a beach. 87 00:12:09.170 --> 00:12:23.330 Laura Mulrooney: But it's a little bit further south, and when we were and yeah we'll talk some more about this in a few minutes, once again, if you have questions you want to send them the chat we can make sure to hit those so as well, but will also will talk about this, too, in a few minutes. 88 00:21:38.090 --> 00:12:25.000 Laura Mulrooney: Okay, so let's take a look at what we've gotten drawn for this one too now and what you want to start with your drawing. 89 00:12:25.001 --> 00:12:32.060 Laura Mulrooney: Okay, so let's take a look at what we've gotten drawn for this one too now and what you want to start with your drawing. 90 00:12:33.440 --> 00:12:33.950 Laura Mulrooney: So. 91 00:12:36.110 --> 00:12:37.370 Laura Mulrooney: This one over here this. 92 00:12:38.750 --> 00:12:48.560 Laura Mulrooney: So once again she's labeled the top of the page, which is good it's a good practice to be in and then she can see her units here which she's got a labeled a much different scale this time is about one foot. 93 00:12:48.950 --> 00:12:58.670 Laura Mulrooney: She wants again that got the numbers, where she could go through, and later explain what's actually there, and she kind of has done that, here too, and then she's also got a key for the things that she noticed that she included here. 94 00:13:00.140 --> 00:13:02.090 Laura Mulrooney: Which we'll talk about some a little bit to. 95 00:13:03.260 --> 00:13:05.690 Laura Mulrooney: towards you want to go ahead and talk and we'll give us a minute Jamie. 96 00:13:06.470 --> 00:13:21.440 Laura Mulrooney: Sure, so one thing that we can notice this picture is the orange coloring threw out so here if you were able to access the field trip before our live session, you would know that this cookie dough was deposited on top of the Hawthorne unit. 97 00:13:22.280 --> 00:13:29.810 Laura Mulrooney: Which is a unit that extends around central Florida around southern Georgia, and that is known for having many different layers of clays. 98 00:13:31.010 --> 00:13:38.510 Laura Mulrooney: clays also come, we also know clay comes from chemical weathering often aided by organics and you can see here. 99 00:13:39.200 --> 00:13:51.740 Laura Mulrooney: The bond the photo there is a little bit of a root system that has been eroded away and so it's just interesting to see how all these things come together to see the color that we see, which is the orange clay. 100 00:13:53.630 --> 00:13:59.000 Laura Mulrooney: yeah and sometimes a highlight another thing about this picture which Jamie did a great job of drawing is. 101 00:14:00.020 --> 00:14:06.620 Laura Mulrooney: See so uh we also have not all of these units are rooted in the same way. 102 00:14:07.370 --> 00:14:16.400 Laura Mulrooney: Some of them are what we would call a slope from farmers versus cliff formers um So you can see Jamie also drew kind of a profile to try to show what was eroded more. 103 00:14:17.000 --> 00:14:22.700 Laura Mulrooney: Until you can see that we've got this layer here that has really, really it's got a good. 104 00:14:23.240 --> 00:14:30.830 Laura Mulrooney: it's very coarse grained on which is also a picture of it over here and that layers sticking out, you can actually see there's like a shelf underneath it. 105 00:14:31.220 --> 00:14:38.450 Laura Mulrooney: were then there's the units that are under at the House other a little bit finer grained there's probably i'm probably more matrix in there as well. 106 00:14:39.110 --> 00:14:45.020 Laura Mulrooney: But you see you can draw a profile like this if you have the time that's also something that you could include. 107 00:14:45.770 --> 00:14:53.210 Laura Mulrooney: In a written description, but so generally, we would call these ones that stick out those would be if there was a unit, we would say that that is a clip former. 108 00:14:53.420 --> 00:15:00.380 Laura Mulrooney: vertices ones that are undercut we would call that a slope former because if you were to think about it on a much, much larger scale like something you would see out West. 109 00:15:00.980 --> 00:15:05.900 Laura Mulrooney: These ones that are under cutter actually going to be weathering Downs they're going to be sticking out further at the base and they are at the top. 110 00:15:09.290 --> 00:15:14.270 Laura Mulrooney: So does anyone else, want to show us their drawing and so maybe there's other things that stood out to y'all as well. 111 00:15:21.380 --> 00:15:22.340 Laura Mulrooney: If not that's okay. 112 00:15:22.850 --> 00:15:28.490 Anita Marshall: This is all fairly well liquefied like if I was gonna scrape a rock hammer across it. 113 00:15:28.970 --> 00:15:33.590 Laura Mulrooney: Other than the red clays yes, the Red clays came off on everything we touched. 114 00:15:34.790 --> 00:15:39.710 Laura Mulrooney: But the rest of it actually we we had a piece of it that we forgot the we left it department. 115 00:15:40.910 --> 00:15:48.620 Laura Mulrooney: know but it's it's a rocket saw this is actually what they built the force out there's the St Augustine ford's is built, out of these units. 116 00:15:50.900 --> 00:15:53.720 Laura Mulrooney: yeah so they've built an entire This is very. 117 00:15:53.810 --> 00:15:55.580 Laura Mulrooney: Important you know how old do this. 118 00:15:57.740 --> 00:15:59.570 Laura Mulrooney: Over 315 years yeah. 119 00:15:59.600 --> 00:16:00.470 Anita Marshall: yeah yeah. 120 00:16:00.590 --> 00:16:04.400 Laura Mulrooney: Five cannon blessed so it's very well provide them nothing's coming out. 121 00:16:05.000 --> 00:16:11.270 Anita Marshall: yeah you know the fun fact about the the fort and the coke INA. 122 00:16:12.260 --> 00:16:19.250 Anita Marshall: You know they built the fort extra thick because there's never been a Fort built out of this kind of rock ever anywhere. 123 00:16:19.670 --> 00:16:28.880 Anita Marshall: And they were worried that it wouldn't be very Sturdy, so they built the walls just incredibly thick to make up for what they assumed was a wimpy rock. 124 00:16:29.690 --> 00:16:39.470 Anita Marshall: And it turns out that because of the orientation of the shells and how their lives defied that they are incredibly good at absorbing shock so. 125 00:16:40.190 --> 00:16:56.690 Anita Marshall: This word is famous for having cannonballs literally just bounce off the outside of the forest, so we would shoot cannibals at it and the shells would absorb the shock and the cannibals would just fall off that the exterior of the port, which I think is a really cool thing. 126 00:16:57.560 --> 00:16:58.400 Definitely. 127 00:17:03.380 --> 00:17:15.500 Laura Mulrooney: Okay, is anyone else wants to share their as go right ahead we're happy to once again we'll talk about anything else if there's any questions that you have about what future either um but if not, we can also move on for next. 128 00:17:16.850 --> 00:17:19.580 Hazel Gordon: Year tazewell, then I have one question about the. 129 00:17:20.840 --> 00:17:22.790 Hazel Gordon: The features that that are. 130 00:17:23.840 --> 00:17:34.010 Hazel Gordon: diagonal lines in this case it's running through the show layer and and then the sort of terraces or whatever they are that separate. 131 00:17:35.090 --> 00:17:40.100 Hazel Gordon: Other parts of the formation What are those do to do you know. 132 00:17:40.730 --> 00:17:49.460 Laura Mulrooney: um I don't know that's a good point I do see the diagonal lines that you're talking about I know that there is betting, but clearly that's not the product of betting on. 133 00:17:51.380 --> 00:17:54.890 Laura Mulrooney: It could be an original feature I don't think that it's a structural one. 134 00:17:55.490 --> 00:18:01.310 Sandor Ricketts: couldn't be just partial alignment of the shells that you're you're seeing because of the alignment. 135 00:18:02.270 --> 00:18:03.440 Laura Mulrooney: It absolutely could. 136 00:18:05.060 --> 00:18:05.480 Laura Mulrooney: yeah. 137 00:18:07.610 --> 00:18:13.190 Sandor Ricketts: Because it's in the upper layer as well, even though it's poorly started, you can see some lemonade and running through it. 138 00:18:14.870 --> 00:18:23.960 Laura Mulrooney: that's true yeah no that's a good point they probably as you can notice, most of the shells on an upper surface are always flat on its face probably some sort of orientation. 139 00:18:26.300 --> 00:18:26.750 Hazel Gordon: Thanks. 140 00:18:27.560 --> 00:18:27.920 yeah. 141 00:18:29.000 --> 00:18:40.100 Anita Marshall: yeah and it is interesting to know how very different that lower layer looks from even the the layer up above it, you know you've got the difference in Shell size but. 142 00:18:40.970 --> 00:18:48.620 Anita Marshall: Even the amount of matrix like there must have been some significant shift in the depth positional environment between these. 143 00:18:51.440 --> 00:18:51.860 Laura Mulrooney: yeah. 144 00:18:52.670 --> 00:18:57.650 Sandor Ricketts: Just just a question is it a root system where the pencil sits or is it something else. 145 00:18:57.920 --> 00:19:04.160 Laura Mulrooney: We think it's a root system based on these other pictures we saw be out, probably, we do think it's a rigged system. 146 00:19:05.300 --> 00:19:06.680 So fossilized. 147 00:19:08.390 --> 00:19:21.320 Laura Mulrooney: I don't know that it's fossilized um it's not really it's definitely dry right i'm pretty proud that they would break apart, when you grab them but um I wouldn't say fossilized. 148 00:19:23.570 --> 00:19:23.900 yeah. 149 00:19:25.220 --> 00:19:26.990 Anita Marshall: This is us on the beat. 150 00:19:31.010 --> 00:19:35.030 Anita Marshall: This is this cross section he's he's trying very diligently. 151 00:19:35.270 --> 00:19:36.560 Laura Mulrooney: he's doing a great job. 152 00:19:39.320 --> 00:19:44.300 Nikita Kepezhinkas: Are the possible almost all by valve or or did you guys see some other stuff and. 153 00:19:45.530 --> 00:19:46.850 Laura Mulrooney: I saw only by bows. 154 00:19:47.300 --> 00:19:47.600 Okay. 155 00:19:50.180 --> 00:20:00.170 Laura Mulrooney: yeah and they were all they were all pretty similar there was nothing that really necessarily stuck out in both like size and shape that they were all pretty much the same. 156 00:20:01.460 --> 00:20:06.140 Laura Mulrooney: Within layers yeah within layers but i'm all by balance for sure. 157 00:20:09.680 --> 00:20:27.020 Laura Mulrooney: Okay um so we're going to switch gears a little bit now we're actually going to go through a bit of a mapping exercise which, if you had looked at this Previously, it was not available, but we have now made it available this is going to be yourself three um. 158 00:20:28.820 --> 00:20:35.270 Laura Mulrooney: And so we will encourage this to be a good group assignments, and I am going to share. 159 00:20:36.980 --> 00:20:37.490 link. 160 00:20:42.350 --> 00:20:42.890 Okay. 161 00:20:48.770 --> 00:20:50.870 Laura Mulrooney: So this way we can all work on this together. 162 00:20:55.490 --> 00:20:55.850 Here we go. 163 00:20:56.960 --> 00:21:06.620 Laura Mulrooney: um so jam board is just it's a Google it's the same thing it's like a Google Doc or whatnot but it allows you to actually draw a little bit more freeform so. 164 00:21:07.520 --> 00:21:23.060 Laura Mulrooney: The one that I just shared with y'all on if you go over like to the side here, you can select an eraser you can select a different type of pen or a paintbrush and you can select the color draw and there's an undo one as well um. 165 00:21:24.590 --> 00:21:32.390 Laura Mulrooney: yeah so we encourage this is our mapping activity it's a bit different to try to make it work online in a website. 166 00:21:33.440 --> 00:21:37.520 Laura Mulrooney: But we got a series of map here, this is along the blue Ridge parkway up in North Carolina. 167 00:21:38.690 --> 00:21:42.290 Laura Mulrooney: And so we walk you through the units here which we encourage you to read through. 168 00:21:43.430 --> 00:21:53.420 Laura Mulrooney: And we will kind of will we're here to answer questions, but we encourage you to talk with each other to try to make sense of this and will kind of take a backseat. 169 00:21:54.500 --> 00:22:00.740 Laura Mulrooney: And then to if you make your observations, so we have each broken into a letter which then corresponds to the letter on the map. 170 00:22:01.760 --> 00:22:03.200 Laura Mulrooney: To try to map this area. 171 00:22:04.760 --> 00:22:16.970 Laura Mulrooney: Once again we're happy to answer questions as you go through this, but we do encourage you to work with each other more to try to bounce ideas off because field work any good mapping exercise, it should be between you and a group of partners um. 172 00:22:18.680 --> 00:22:21.350 Laura Mulrooney: It works, a lot better if you work in teams that. 173 00:22:23.210 --> 00:22:26.060 Derek Thorn: says that I need on access. 174 00:22:27.320 --> 00:22:27.500 Derek Thorn: To. 175 00:22:27.710 --> 00:22:32.060 Laura Mulrooney: Let me see i'm going to stop sharing for a minute, just so I can take a look at this. 176 00:22:46.340 --> 00:22:51.530 Anita Marshall: And when you have a chance, will you just put the link to the website in the chat. 177 00:22:51.950 --> 00:22:59.960 Laura Mulrooney: Of course Okay, so I think that the link, I think I change it to edit um let me know if it doesn't work and then also. 178 00:23:01.220 --> 00:23:02.450 Laura Mulrooney: let's send this. 179 00:23:19.550 --> 00:23:20.840 Derek Thorn: I have access, now, thank you. 180 00:23:21.080 --> 00:23:26.930 Laura Mulrooney: yeah of course glad to go working, and so we all have access to so we'll kind of read through with you. 181 00:23:28.850 --> 00:23:35.570 Laura Mulrooney: But we encourage you to work together and do this and, of course, ask any questions that can be either about mapping or about anything that you see. 182 00:23:37.850 --> 00:23:38.150 ya. 183 00:23:58.100 --> 00:24:00.050 Derek Thorn: know what did the letters mean again. 184 00:24:06.260 --> 00:24:09.020 Laura Mulrooney: yeah so the letters correspond to a stop so. 185 00:24:10.070 --> 00:24:17.000 Laura Mulrooney: You see, on the map that there's letter A and B and whatnot and if you go through, and you see at the bottom of that first page that I sent a link to. 186 00:24:18.260 --> 00:24:21.200 Laura Mulrooney: The bottom of the page here i'll share my screen instead of trying to describe this. 187 00:24:24.920 --> 00:24:31.520 Laura Mulrooney: Here, so at the bottom of the page there's a and so, if you click a it takes you to Okay, this is the observations that we made us at a. 188 00:24:32.690 --> 00:24:36.110 Laura Mulrooney: And if you hit be here, it takes you to the observations we made it be. 189 00:24:37.490 --> 00:24:42.230 Laura Mulrooney: Yes, and so obviously you're going to have to do some extrapolating to figure out what's going on between them. 190 00:24:42.950 --> 00:24:54.320 Laura Mulrooney: And we expect that and we also know that this is over a State wide scale, so we encourage you to be generous with that, but also just keep in mind that there's nothing too complicated going on here. 191 00:26:46.100 --> 00:24:56.000 Anita Marshall: may have missed this part do we have designated colors that we're using for the different. 192 00:24:56.001 --> 00:25:03.930 Anita Marshall: Should we, like each take letter or should we talk through each one. 193 00:25:05.640 --> 00:25:16.620 Laura Mulrooney: um we can do whatever y'all want to do if you want to do a letter at a time and determine what what you think it is, I think that might be the best way that's more collaborative yeah yeah. 194 00:25:18.750 --> 00:25:22.050 Laura Mulrooney: Do you want me to share my screen, as we go through this i'm. 195 00:25:22.620 --> 00:25:24.600 Anita Marshall: Sure, we could yeah just build it. 196 00:25:25.140 --> 00:25:25.530 yeah. 197 00:26:05.430 --> 00:26:15.570 Laura Mulrooney: Okay, so I also encourage you to have this looked up just pulled up just because some of these think I have some 360 pictures that are probably easier this one's really bad sunless. 198 00:26:17.280 --> 00:26:21.690 Laura Mulrooney: they're probably easier for y'all to interact with rather than me trying to show you around. 199 00:26:22.800 --> 00:26:25.440 Laura Mulrooney: But I also encourage you to possibly have the. 200 00:26:25.440 --> 00:26:30.750 Laura Mulrooney: original page pulled up as well just because we do provide you these symptoms of what each unit looks like. 201 00:26:32.610 --> 00:26:40.140 Laura Mulrooney: And so you can talk with each other to see what you think this is there's only three units that we're looking at it's it's going to be one of those three on. 202 00:26:41.490 --> 00:26:43.830 Laura Mulrooney: And I also include reference pictures so. 203 00:26:44.850 --> 00:26:53.100 Laura Mulrooney: yeah feel free to talk with each other and also feel free to to draw it go ahead and draw like i'm on the map, if you think you know what's going on. 204 00:26:55.290 --> 00:27:01.320 Laura Mulrooney: yeah if you've never mapped before what your what your main goal right now is to look at our three units that we described. 205 00:27:01.890 --> 00:27:09.660 Laura Mulrooney: In this on the first page and then, as we go through each letter you want to make connections what rock like what what rock we're looking at now which. 206 00:27:10.470 --> 00:27:17.790 Laura Mulrooney: Like what minerals are in it, what color is look like and how does that coincide with one of those three formations that we talked about in the beginning. 207 00:28:48.930 --> 00:27:21.000 Laura Mulrooney: Okay, so Does anyone want to point out any observations that they see. 208 00:27:21.001 --> 00:27:26.740 Laura Mulrooney: Okay, so Does anyone want to point out any observations that they see. 209 00:27:27.850 --> 00:27:35.470 Laura Mulrooney: I will say that the color of the crop should be a clue as well as the presence of these white veins throughout i'm. 210 00:27:36.970 --> 00:27:40.360 Laura Mulrooney: Sending one have an idea anyone want to shout out what they think the answer is. 211 00:27:41.560 --> 00:27:45.430 Laura Mulrooney: Or you can just go ahead and put it on the map it's okay to be wrong, we can figure that out. 212 00:27:50.020 --> 00:27:50.380 Sandor Ricketts: i'm. 213 00:27:51.670 --> 00:27:56.590 Sandor Ricketts: Not the teachers I won't talk hello, and the rest of the guys the rest of us, you want to try and do it, so we. 214 00:27:56.710 --> 00:27:57.670 Sandor Ricketts: Can just figure out. 215 00:27:57.700 --> 00:27:58.360 Sandor Ricketts: What it is. 216 00:27:59.680 --> 00:28:00.760 Sandor Ricketts: Who wants to do the drawing. 217 00:28:11.920 --> 00:28:13.840 Anita Marshall: I can try some mouse drawing. 218 00:28:15.070 --> 00:28:15.670 that's fine. 219 00:28:17.800 --> 00:28:25.720 Sandor Ricketts: Alright So what do have a based on the look of it i'm figuring is that cohesive group. 220 00:28:27.610 --> 00:28:34.660 Derek Thorn: yeah that's what i'm thinking as well that a very distinct white vein is very characteristic of that group. 221 00:28:38.650 --> 00:28:39.730 Derek Thorn: and seeing. 222 00:28:41.500 --> 00:28:43.990 Derek Thorn: high volume of all for creation in it. 223 00:28:50.500 --> 00:28:58.870 Anita Marshall: So i'm just gonna put a little.of color next to the a because, since we don't know what these other outcrops are going to be. 224 00:28:59.890 --> 00:29:13.570 Anita Marshall: You know, we can't really infer how much of this to color blue so i'm just going to put a little.by the a and then we can sort of draw in our larger math later, when we know what all the colors are. 225 00:29:14.200 --> 00:29:16.930 Sandor Ricketts: OK that's fine be. 226 00:29:24.700 --> 00:29:27.010 Sandor Ricketts: I guess these the ashy metamorphic. 227 00:29:29.200 --> 00:29:30.490 Derek Thorn: that's i'm thinking as well. 228 00:29:37.630 --> 00:29:40.660 Derek Thorn: Do we know which i'm group came first. 229 00:29:43.960 --> 00:29:46.480 Derek Thorn: Which is the oldest group do you know. 230 00:29:46.540 --> 00:29:54.970 Nikita Kepezhinkas: there's um there's there's time on the page right before a where you're looking at three unit to give the agent, I believe that created the older. 231 00:29:55.990 --> 00:29:56.290 Derek Thorn: Okay. 232 00:29:56.680 --> 00:29:58.360 Nikita Kepezhinkas: I think most of billionaire. 233 00:29:59.530 --> 00:30:01.510 Nikita Kepezhinkas: And then I can update to the other. 234 00:30:02.860 --> 00:30:08.920 Sandor Ricketts: 720 266 and 770 669. 235 00:30:10.900 --> 00:30:17.530 Sandor Ricketts: Though sorry i'm The co leader is 1600 to 541. 236 00:30:18.730 --> 00:30:28.660 Sandor Ricketts: Then the ash is 7182686, then the alligator is 717 2669 okay. 237 00:30:32.470 --> 00:30:35.500 Sandor Ricketts: Alright, so we have be Mr ice. 238 00:30:55.480 --> 00:31:02.530 Sandor Ricketts: i'm leaning leaning towards the actual again on that one because of the reddish broaden their along with meaning. 239 00:31:10.750 --> 00:31:14.170 Anita Marshall: hang on I gotta get sidetracked. 240 00:31:25.660 --> 00:31:26.200 Derek Thorn: This is the. 241 00:31:43.120 --> 00:31:45.850 Sandor Ricketts: Which one you thinking i'm thinking to ash. 242 00:31:47.650 --> 00:31:49.300 Derek Thorn: On the plans are throwing me off. 243 00:31:50.590 --> 00:32:10.450 Sandor Ricketts: I ignore the first one, look at the 360 because what i'm feeling is the second photograph, for example, of the chest, or you have that reddish i'm not sure if that's i'm just weathering that showing up along with it, which dominant, on the other, photographs. 244 00:32:22.000 --> 00:32:24.220 Anita Marshall: yeah this one's definitely a little trickier. 245 00:32:29.830 --> 00:32:34.240 Anita Marshall: Okay we're gonna go with the ash on this one. 246 00:32:37.930 --> 00:32:41.110 Sandor Ricketts: I think that's the closest one to work with right no. 247 00:32:45.880 --> 00:32:47.710 Sandor Ricketts: yeah because we're not getting the Nice. 248 00:32:50.980 --> 00:32:54.040 Sandor Ricketts: Nice veining and grey from the. 249 00:32:55.060 --> 00:33:03.820 Sandor Ricketts: Quito and then the alligators a little bit harder to decipher any callers or patterns. 250 00:33:05.440 --> 00:33:08.680 Derek Thorn: look into 3D close up matt. 251 00:33:18.190 --> 00:33:19.540 Sandor Ricketts: I don't think that's a nice. 252 00:33:24.010 --> 00:33:24.670 Sandor Ricketts: alligator. 253 00:33:25.750 --> 00:33:26.470 back for me. 254 00:33:29.740 --> 00:33:30.970 Derek Thorn: Which one is this the D. 255 00:33:32.530 --> 00:33:33.400 Sandor Ricketts: And this is a. 256 00:33:35.500 --> 00:33:37.330 Sandor Ricketts: d yeah This is where i'm Dino. 257 00:33:47.950 --> 00:33:49.060 Derek Thorn: yeah I think that's the. 258 00:33:52.240 --> 00:33:53.350 Sandor Ricketts: Your things to Quito. 259 00:33:54.520 --> 00:33:55.120 Sandor Ricketts: For D. 260 00:33:58.600 --> 00:34:00.370 Derek Thorn: Is that what you thought it was as well. 261 00:34:00.430 --> 00:34:04.210 Sandor Ricketts: don thinking more to the the ash because of. 262 00:34:06.370 --> 00:34:10.870 Sandor Ricketts: The excessive weathering and. 263 00:34:12.460 --> 00:34:17.860 Sandor Ricketts: From the well yeah the excess of weather in there we're seeing a lot of the red the iron oxide. 264 00:34:20.980 --> 00:34:25.210 Nikita Kepezhinkas: And there's none of that veining that court court stuff yeah. 265 00:34:25.900 --> 00:34:27.310 Sandor Ricketts: This thing to courts veining. 266 00:34:32.500 --> 00:34:35.260 Derek Thorn: Looking at the the roadside outcrop. 267 00:34:38.140 --> 00:34:39.340 Derek Thorn: sleep there's some. 268 00:34:48.310 --> 00:34:49.090 Nikita Kepezhinkas: Some what that. 269 00:34:51.010 --> 00:34:57.220 Derek Thorn: looks like there might be some courts veins very faint i'm looking at the road. 270 00:34:57.820 --> 00:34:58.720 Nikita Kepezhinkas: yeah but the. 271 00:34:58.840 --> 00:35:02.590 Nikita Kepezhinkas: first one was like they were like a foot wide and they were like 20 of them. 272 00:35:02.980 --> 00:35:03.700 Nikita Kepezhinkas: yeah right. 273 00:35:04.540 --> 00:35:05.710 Sandor Ricketts: A lot more distinctive. 274 00:35:08.260 --> 00:35:12.730 Sandor Ricketts: And the fracturing is a lot more on the D. 275 00:35:13.960 --> 00:35:16.630 Sandor Ricketts: Which kind of looks like the ashes well. 276 00:35:17.710 --> 00:35:18.370 Derek Thorn: yeah. 277 00:35:18.880 --> 00:35:23.620 Sandor Ricketts: i'm sure we'll get to answer later on, so we can look into stick one in, and it was to fire off. 278 00:35:24.730 --> 00:35:29.170 Derek Thorn: yeah i'm really looking at it now yeah and i'm going to yeah I agree with you guys, that is, that ash. 279 00:35:31.930 --> 00:35:34.540 Sandor Ricketts: All right, well, that sketched in and either. 280 00:35:48.130 --> 00:35:50.440 Derek Thorn: So right now yep. 281 00:35:52.870 --> 00:36:01.090 Sandor Ricketts: nice to have a limited as well image, but we're back today heavily weather and fractured. 282 00:36:03.970 --> 00:36:04.870 Derek Thorn: or he. 283 00:36:07.180 --> 00:36:09.280 Sandor Ricketts: Or am I, on the road when i'm on dx actually. 284 00:36:14.110 --> 00:36:15.250 Derek Thorn: Very blue. 285 00:36:17.200 --> 00:36:17.740 Sandor Ricketts: For D. 286 00:36:18.580 --> 00:36:20.710 Derek Thorn: or E, excuse me, is very blue. 287 00:36:21.940 --> 00:36:23.590 Sandor Ricketts: I think i'm getting confused as to where. 288 00:36:25.090 --> 00:36:26.620 Sandor Ricketts: We were an ear will indeed. 289 00:36:32.860 --> 00:36:36.430 Hazel Gordon: yeah I thought we all were kind of identify D. 290 00:36:37.480 --> 00:36:38.050 Anita Marshall: yeah I think. 291 00:36:39.370 --> 00:36:45.370 Hazel Gordon: I think he looks like an alligator because of the blue color but I don't see much more. 292 00:36:47.560 --> 00:36:49.030 Derek Thorn: You looks like alligator. 293 00:36:50.170 --> 00:36:50.620 Sandor Ricketts: What did we. 294 00:36:51.700 --> 00:36:52.750 Sandor Ricketts: What did we put for see. 295 00:36:55.930 --> 00:36:56.410 Derek Thorn: ash. 296 00:36:56.890 --> 00:36:58.090 Sandor Ricketts: ash okay. 297 00:37:05.560 --> 00:37:07.090 Sandor Ricketts: and be what we're calling the. 298 00:37:08.230 --> 00:37:08.710 Anita Marshall: ash. 299 00:37:10.660 --> 00:37:14.380 Sandor Ricketts: And then he yeah that's the blue yeah. 300 00:37:14.500 --> 00:37:16.600 Sandor Ricketts: alligator alligator. 301 00:37:30.460 --> 00:37:32.170 Anita Marshall: Alright, so we're back to striking stuff here. 302 00:37:35.950 --> 00:37:38.230 Sandor Ricketts: throws off on these PICs, but we can see. 303 00:37:40.690 --> 00:37:47.170 Sandor Ricketts: The 360s fractured can receive endings yeah we can still see veining on a 360 when those factor. 304 00:37:50.950 --> 00:37:52.930 Derek Thorn: On F there we go. 305 00:37:55.210 --> 00:37:56.110 Sandor Ricketts: What what you're thinking. 306 00:38:09.970 --> 00:38:23.080 Sandor Ricketts: Well we'll have to keep in mind that the ash does have meaning as well, but it's more for darker color with the training versus that i'm more actually. 307 00:38:24.700 --> 00:38:30.190 Nikita Kepezhinkas: into Kuwait, also on fully aided relatively or it's just nice thick right so. 308 00:38:32.440 --> 00:38:34.960 Nikita Kepezhinkas: it's up at the unit description yeah. 309 00:38:40.180 --> 00:38:40.750 Anita Marshall: Good point. 310 00:38:43.120 --> 00:38:49.690 Anita Marshall: But it's lighter and I mean the the reference pictures for the ashland too dark for this rock maybe not. 311 00:38:56.800 --> 00:39:00.430 Sandor Ricketts: Any other pictures I don't think any of the pictures really do it does justice. 312 00:39:00.850 --> 00:39:01.450 yeah. 313 00:39:03.280 --> 00:39:08.500 Anita Marshall: All right, I can just put what are we gonna put for now, maybe ash. 314 00:39:09.460 --> 00:39:11.470 Sandor Ricketts: yeah we can put an astronaut question mark. 315 00:39:16.210 --> 00:39:16.840 Sandor Ricketts: So JI. 316 00:39:22.960 --> 00:39:25.840 Sandor Ricketts: JI, we can see if we go with a Quito for g. 317 00:39:27.370 --> 00:39:28.060 Anita Marshall: yeah. 318 00:39:51.460 --> 00:39:51.850 looks like. 319 00:39:54.550 --> 00:39:54.850 Sandor Ricketts: we're. 320 00:39:56.800 --> 00:40:00.940 Sandor Ricketts: Having a fractured when the oxidation staining similar to the action. 321 00:40:09.010 --> 00:40:11.860 Sandor Ricketts: Everybody agrees with the ash for that one. 322 00:40:12.580 --> 00:40:13.480 Derek Thorn: For it. 323 00:40:13.990 --> 00:40:14.230 yeah. 324 00:40:16.630 --> 00:40:17.410 Hazel Gordon: I think I would. 325 00:40:18.220 --> 00:40:19.570 Sandor Ricketts: yeah yeah. 326 00:40:25.480 --> 00:40:26.500 Sandor Ricketts: looks at the same thing. 327 00:40:28.930 --> 00:40:29.890 Hazel Gordon: yeah pretty orange. 328 00:40:31.600 --> 00:40:32.740 Hazel Gordon: orange as again. 329 00:40:33.310 --> 00:40:34.720 Sandor Ricketts: yeah we go to actually do any up. 330 00:40:54.190 --> 00:40:54.490 Oh. 331 00:40:59.350 --> 00:41:01.570 Sandor Ricketts: Based on that photograph in the bottom right. 332 00:41:01.840 --> 00:41:02.290 yeah. 333 00:41:04.900 --> 00:41:05.170 Sandor Ricketts: yeah. 334 00:41:08.800 --> 00:41:11.050 Nikita Kepezhinkas: What we're saying like really small. 335 00:41:12.130 --> 00:41:12.790 Nikita Kepezhinkas: repeat right. 336 00:41:14.980 --> 00:41:16.870 Nikita Kepezhinkas: That are sorry go ahead. 337 00:41:18.580 --> 00:41:18.970 Anita Marshall: Sorry. 338 00:41:21.070 --> 00:41:23.950 Sandor Ricketts: No yes in the bottom right was really small in terms of scaling. 339 00:41:24.010 --> 00:41:30.670 Nikita Kepezhinkas: yeah that's The keys right on the left of that right so that's like that's like miniscule right. 340 00:41:31.000 --> 00:41:42.250 Sandor Ricketts: yeah, but if we look at like the key look at both queda image on the first one is still just a keys just a key right beside that vein, which is not a vein isn't much thicker than the key. 341 00:41:42.970 --> 00:41:43.360 I guess. 342 00:41:47.920 --> 00:41:50.230 Sandor Ricketts: I know we have that darker Gray. 343 00:41:52.420 --> 00:41:53.800 Sandor Ricketts: Or is it to listen to the black. 344 00:41:55.090 --> 00:41:56.590 Derek Thorn: we're on K now. 345 00:41:57.850 --> 00:41:59.290 Sandor Ricketts: Jay Jay. 346 00:42:01.090 --> 00:42:02.260 Hazel Gordon: queda did we say. 347 00:42:03.220 --> 00:42:03.520 Derek Thorn: yeah. 348 00:42:03.730 --> 00:42:05.860 Derek Thorn: I know for Jay we said ash. 349 00:42:06.790 --> 00:42:07.120 Really. 350 00:42:12.670 --> 00:42:18.940 Sandor Ricketts: The letters at the top, because I got confused with the letter being at the bottom, but the letter that we're we're on is at the top. 351 00:42:19.210 --> 00:42:22.840 Hazel Gordon: Top yeah so I still on Jay yeah. 352 00:42:24.490 --> 00:42:29.710 Nikita Kepezhinkas: I look back at stuff a and the outcrop pictures are I mean those are pretty big thing right. 353 00:42:30.250 --> 00:42:35.980 Sandor Ricketts: Now so you're you're thinking you're thinking J might ash instead of Quito. 354 00:42:36.850 --> 00:42:43.930 Nikita Kepezhinkas: yeah I don't yeah I don't think it's the alligator I think it's part of it too i'm leaning more ash, but I mean I don't know what you guys think so. 355 00:42:45.550 --> 00:42:49.240 Sandor Ricketts: The fracturing is there oxidation is there. 356 00:42:51.520 --> 00:42:52.000 Sandor Ricketts: Anybody. 357 00:42:52.720 --> 00:42:54.040 Sandor Ricketts: Have a darker color. 358 00:42:55.780 --> 00:43:04.210 Hazel Gordon: But I was looking at the upper left to end photo and the veins look fairly large their their cause vertical this point. 359 00:43:08.650 --> 00:43:10.030 Sandor Ricketts: let's pick one and stick a question. 360 00:43:10.180 --> 00:43:11.890 Nikita Kepezhinkas: On the left hand photo hazel. 361 00:43:12.130 --> 00:43:18.340 Hazel Gordon: yeah upper upper left where you see the horizontal looking by vertical veins. 362 00:43:20.980 --> 00:43:21.310 Hazel Gordon: whitish. 363 00:43:21.430 --> 00:43:23.770 Sandor Ricketts: The 360 you're talking on the left or. 364 00:43:26.080 --> 00:43:28.780 Hazel Gordon: Oh sorry i'm looking at the field guide. 365 00:43:36.310 --> 00:43:38.800 Hazel Gordon: Well i'll go with whatever you guys think. 366 00:43:40.360 --> 00:43:43.210 Anita Marshall: Are we painted site which which page we. 367 00:43:43.780 --> 00:43:44.410 Sandor Ricketts: Were on Jay. 368 00:43:51.190 --> 00:43:53.470 Sandor Ricketts: that's a question mark, just in case. 369 00:43:54.490 --> 00:43:56.560 Hazel Gordon: yeah there's orange and there's rain. 370 00:43:58.720 --> 00:43:58.990 yeah. 371 00:44:06.220 --> 00:44:06.610 Hazel Gordon: Why not. 372 00:44:10.720 --> 00:44:11.740 Sandor Ricketts: All right, okay. 373 00:44:18.430 --> 00:44:18.820 Derek Thorn: yeah. 374 00:44:19.000 --> 00:44:19.390 yeah. 375 00:44:22.240 --> 00:44:22.810 Hazel Gordon: Good for that. 376 00:44:24.400 --> 00:44:24.730 Hazel Gordon: l. 377 00:44:25.210 --> 00:44:26.860 Hazel Gordon: Sure, oh oh. 378 00:44:26.890 --> 00:44:28.180 Hazel Gordon: They even said it. 379 00:44:32.980 --> 00:44:35.470 Nikita Kepezhinkas: Did yeah and that whole paragraph. 380 00:44:35.770 --> 00:44:36.130 Hazel Gordon: yeah. 381 00:44:36.220 --> 00:44:38.230 Nikita Kepezhinkas: Right good thing we got it before we read it right. 382 00:44:42.340 --> 00:44:43.810 Hazel Gordon: Oh gosh um. 383 00:45:00.100 --> 00:45:01.660 Sandor Ricketts: Right yeah. 384 00:45:03.430 --> 00:45:04.480 Derek Thorn: This looks like ash. 385 00:45:10.450 --> 00:45:12.280 Derek Thorn: Is it has cemetery and that its. 386 00:45:13.930 --> 00:45:15.850 Derek Thorn: Center and metamorphic. 387 00:45:17.140 --> 00:45:22.660 Laura Mulrooney: So you don't need to draw point for l you can just read what's written there and skip it. 388 00:45:24.310 --> 00:45:24.640 Hazel Gordon: Oh. 389 00:45:29.560 --> 00:45:29.920 Hazel Gordon: Okay. 390 00:45:31.120 --> 00:45:31.840 Ashton. 391 00:45:36.400 --> 00:45:36.940 Sandor Ricketts: For him. 392 00:45:44.080 --> 00:45:47.740 Nikita Kepezhinkas: I think I was already labeled great, but it. 393 00:45:48.850 --> 00:45:51.220 Nikita Kepezhinkas: also looks like a Granite picture is almost. 394 00:45:51.730 --> 00:45:56.050 Anita Marshall: that's labeled as like something different than everything else. 395 00:45:56.920 --> 00:45:59.680 Laura Mulrooney: Okay yeah we'll talk about it when you finish. 396 00:46:01.030 --> 00:46:01.870 When i'm no. 397 00:46:02.890 --> 00:46:03.340 Hazel Gordon: No yes. 398 00:46:37.690 --> 00:46:38.980 Derek Thorn: i'm thinking alligator. 399 00:46:43.480 --> 00:46:43.990 Nikita Kepezhinkas: yeah. 400 00:46:51.610 --> 00:46:54.400 Sandor Ricketts: it's missing Michael Sheen that's, the only thing. 401 00:46:55.630 --> 00:46:59.530 Sandor Ricketts: are actually the photograph on the left here, we could probably go to alligator. 402 00:47:00.760 --> 00:47:05.230 Sandor Ricketts: Beside that yellow blue sandal blue black sandal it has that. 403 00:47:08.800 --> 00:47:09.850 Sandor Ricketts: Alright, so we'll go. 404 00:47:10.390 --> 00:47:10.870 Sandor Ricketts: next one. 405 00:47:11.080 --> 00:47:11.380 and 406 00:47:35.230 --> 00:47:36.970 Hazel Gordon: is again. 407 00:47:40.660 --> 00:47:42.250 Hazel Gordon: Those veins look weird. 408 00:47:57.100 --> 00:48:09.700 Sandor Ricketts: Open probably go to colada is not as not having a factor so they'll have a lot of oxidation on the fact that that keys, there were probably getting a scale and i'm vain or something mm hmm. 409 00:48:11.080 --> 00:48:13.420 Sandor Ricketts: Okay yeah we can go on. 410 00:48:14.680 --> 00:48:14.980 Hazel Gordon: Okay. 411 00:48:17.440 --> 00:48:18.400 Sandor Ricketts: yeah I think that's it. 412 00:48:18.790 --> 00:48:20.080 Hazel Gordon: Closing step three. 413 00:48:21.670 --> 00:48:23.770 Laura Mulrooney: Okay, so we're not going to talk about this a little bit. 414 00:48:25.330 --> 00:48:38.350 Laura Mulrooney: So good job you all, did you met first mapping exercise um you there, most of them are right there's only I think what was it two or three that you, you debated on and you went with the wrong one but that's okay. 415 00:48:39.940 --> 00:48:50.920 Laura Mulrooney: So let's talk about what you would do once you made these observations first um so I know you probably didn't have a ton of time to actually read through what that the beginning but. 416 00:48:51.670 --> 00:49:01.270 Laura Mulrooney: there's nothing overly complicated going on here, we were trying to trick you there's no sorts of if there are some complicated things, but I did not include them on this map. 417 00:49:03.580 --> 00:49:15.880 Laura Mulrooney: So what we know is there's going to be a simple progression of units, so at this point if you had this as a real mapping exercise that say your your field methods class have given you or your field camp had given you. 418 00:49:17.200 --> 00:49:30.040 Laura Mulrooney: suppose that this is what the observations you came back on day one, and you have a whole nother day out in the field, so at that point you'd want to say, well, what date what spots, that we have questions on which i'm here i'll share my screen so. 419 00:49:31.750 --> 00:49:40.330 Laura Mulrooney: Based on what you all have it looks like this areas where we would need to do a little bit more work because that seems a little bit out of character it's going to be hard to fit a contact. 420 00:49:40.570 --> 00:49:49.090 Laura Mulrooney: That can be a straight line to get all of the units to match up and then also this one up here would be something we might want to look at again um. 421 00:49:50.200 --> 00:49:58.450 Laura Mulrooney: So, once you went out there, and you would make some more observations you could then which, if you want to go to the closing. 422 00:50:00.130 --> 00:50:05.830 Laura Mulrooney: So these were the sops and we can go through, and actually talk about the sops as we labeled them as they are. 423 00:50:07.600 --> 00:50:12.670 Laura Mulrooney: And so I know that there are colors are a little bit different than yours, because we did this in a different program, to put it together here. 424 00:50:13.360 --> 00:50:22.120 Laura Mulrooney: But so all of these should have been the ash and so now that you've got this, this is not what you turn in you can't just put dots on the map and turn it in, unfortunately. 425 00:50:22.720 --> 00:50:30.940 Laura Mulrooney: But with That being said, this is like a is an easily hundred 200 mile area and so you're going to be inferring some things In between there. 426 00:50:31.480 --> 00:50:38.500 Laura Mulrooney: And so what you want to do is you would ideally if you were in the field, you would have taken some striking depths, you would have actually seen some contacts which. 427 00:50:39.400 --> 00:50:45.490 Laura Mulrooney: We did see some contacts, but there was no place to pull the car off them, unfortunately, so we could not get pictures of them. 428 00:50:47.410 --> 00:50:59.320 Laura Mulrooney: But you'd want to actually fit a contact line here, and so you start to see well Okay, we want all the pinks to be together we went all the blues to be together and we want all the purple's to be together or in your case, all the blues, the Greens and the reds. 429 00:50:59.770 --> 00:51:03.460 Laura Mulrooney: And so to fit that to something you might have something that ends up looking like this. 430 00:51:06.280 --> 00:51:11.170 Laura Mulrooney: So this is a simple, this is a simplified version of what the actual map area looks like. 431 00:51:11.800 --> 00:51:27.160 Laura Mulrooney: But if you wanted to see that we did include down here which you can see, to the actual, this is the actual God North Carolina state map state geologic maps and you can see that, based on where our stops we're located, this is a pretty good assumption, based on the stops that we gave you. 432 00:51:28.420 --> 00:51:32.440 Laura Mulrooney: I will talk a little bit about l which we didn't mention, which is going to lead us into. 433 00:51:33.040 --> 00:51:39.970 Laura Mulrooney: Our little bit of our next activity so l is the grandfather mountain window, which is it's a fault system where there's a bunch of. 434 00:51:40.690 --> 00:51:49.330 Laura Mulrooney: You actually have some false sort of slide it off it's a window into looking into other rocks that are below it and that's where we're our next stop is going to be to look at. 435 00:51:49.810 --> 00:51:58.180 Laura Mulrooney: And, but let's go back and let's look at E G and and and talk about the things that we were hoping that she would have noticed and on all of them, you debated between them. 436 00:52:00.550 --> 00:52:06.340 Laura Mulrooney: And that's Okay, I mean you're not going to get them you're not always going to get everything right the first try so let's go through. 437 00:52:07.630 --> 00:52:23.350 Anita Marshall: I also think that it's useful, especially in a virtual experience to think about not just oh I got that wrong but think about like, if I were in the field, what information would help me better identify this rock. 438 00:52:23.440 --> 00:52:26.230 Laura Mulrooney: Exactly, and we can talk about that some to let's start with. 439 00:52:26.770 --> 00:52:31.480 Anita Marshall: me if you know my missing that would make this easier, more straightforward. 440 00:52:31.660 --> 00:52:32.650 Laura Mulrooney: And that's very helpful. 441 00:52:32.860 --> 00:52:33.610 Anita Marshall: About two. 442 00:52:34.720 --> 00:52:38.230 Laura Mulrooney: yeah so we can talk about some of the things that cause problems for this one. 443 00:52:38.560 --> 00:52:49.630 Laura Mulrooney: I didn't want to cross the road, because it was coming out of the other side of a tunnel and so all the pictures that you have are taken from the other side of the road which, based on the lighting to does not does not give this area justice. 444 00:52:51.340 --> 00:53:06.850 Laura Mulrooney: So he if we look at this here, you can see that it's it's really hard to see the whole rock is in shadow and it's actually I think it's wet to which does not help um but so looking at this point, you want to pull up the dashboard. 445 00:53:09.040 --> 00:53:18.100 Laura Mulrooney: So what we're hoping, is that you would compare this to some of the other ones that you see later and come back to it, so this is going to be part of the ash and. 446 00:53:18.730 --> 00:53:25.390 Laura Mulrooney: The ashes, a extremely varied he came to our discussion yesterday we actually had several people present on this. 447 00:53:26.110 --> 00:53:37.510 Laura Mulrooney: But the ashes extremely varied it's a Meta sedimentary units, there are areas where there's marbles in this unit, there are also those that range them they're typically it has that rusted to it, but not always. 448 00:53:39.220 --> 00:53:40.090 Laura Mulrooney: up close. 449 00:53:40.390 --> 00:53:44.530 Laura Mulrooney: You probably would have seen there's affiliation, but you can't see that from these pictures. 450 00:53:46.630 --> 00:53:53.260 Laura Mulrooney: and also the trees, there may be as difficult so it's worthwhile to note the reasons why you can't notice it from a virtual format and. 451 00:53:53.470 --> 00:54:01.120 Laura Mulrooney: Think about in the field, how you would have fixed that so in the field, ideally, you would have actually been able to get close to this and look at it and see Okay, well, I see affiliation or. 452 00:54:01.450 --> 00:54:09.400 Laura Mulrooney: Okay, I can actually see what kind of a rock this is, I don't see any veins I don't see the blue color that is typical of the alligator um. 453 00:54:11.560 --> 00:54:14.770 Laura Mulrooney: So our next one that will talk about is g. 454 00:54:21.370 --> 00:54:23.380 Laura Mulrooney: So this one I included to try to trick us. 455 00:54:24.790 --> 00:54:26.320 Laura Mulrooney: But uh so. 456 00:54:27.460 --> 00:54:40.450 Laura Mulrooney: This one, if you look at these pictures, you can see that it is a little bit rusted um I think that's some of the things, there are some small veins that are throughout here, but I think some of the things that y'all might have thought were veins are actually just the weathering pattern. 457 00:54:42.520 --> 00:54:48.070 Laura Mulrooney: I mean, there are a few things, but I think it's more of a banding they're more they're actually deformed a little bit here. 458 00:54:49.480 --> 00:54:51.730 Laura Mulrooney: Let me just check the chat sorry see that. 459 00:54:53.170 --> 00:54:54.670 Laura Mulrooney: um so. 460 00:54:56.530 --> 00:55:03.670 Laura Mulrooney: Ideally, what she would look at here, as you can see that the color that it's rusting and none of the other units we're going to rust read um. 461 00:55:04.450 --> 00:55:12.640 Laura Mulrooney: With That being said, this is actually an area where we have a it actually changes from down here, this is just an up here is a nice so it's a contact within the unit. 462 00:55:13.360 --> 00:55:19.150 Laura Mulrooney: And I did include some pictures of some of the veins that are running through here in hopes that I could confuse you and make you think that they were likes. 463 00:55:20.710 --> 00:55:26.110 Laura Mulrooney: what's there not this is just a, this is a secondary vein over here, and this is just part of the affiliation. 464 00:55:28.150 --> 00:55:30.850 Laura Mulrooney: And so, then the last one was an. 465 00:55:32.950 --> 00:55:33.970 Laura Mulrooney: So an. 466 00:55:35.560 --> 00:55:41.350 Laura Mulrooney: What I was hoping to see and the is this picture, right here it's blue. 467 00:55:42.430 --> 00:55:51.190 Laura Mulrooney: Which is characteristic feature of that Union granted you didn't see it in any of the other pictures of this one, but it's also to show you that there can be a lot of variation between. 468 00:55:52.210 --> 00:55:57.850 Laura Mulrooney: units and if you'd have more time with the description i'm sure that you would have noticed that, too, but it's fully it and you can see affiliation here. 469 00:55:58.360 --> 00:56:06.340 Laura Mulrooney: This here might look like a vein is that's just a pattern of web weathering these black and white stripe that are vertical the affiliation it's actually running. 470 00:56:07.000 --> 00:56:20.140 Laura Mulrooney: Down tip like that and it's actually where this is fracturing to, and so you can see in this close up picture, this is blue that's a characteristic feature of this unit and also, if you look at this here it kind of is tend to blue on a larger scale as well. 471 00:56:21.970 --> 00:56:27.670 Laura Mulrooney: But yeah I encourage you later to read through our actual description, where we actually give you some. 472 00:56:28.210 --> 00:56:39.610 Laura Mulrooney: Of we give a little bit more of relation of how you would tie this into a real world mapping exercise where, if you were out in the field to also think about what she would want to do differently if you had more time and you were out in the field. 473 00:56:41.080 --> 00:56:54.640 Laura Mulrooney: You ideally would not base an entire mapping exercise on what did I give you like 15 points you actually would want to look at between them and see if you could find contacts, but based on a mapping exercise of the scale and something that's virtual. 474 00:56:55.960 --> 00:56:59.950 Laura Mulrooney: Managing expectations is also something that I think is is good. 475 00:57:02.050 --> 00:57:13.060 Laura Mulrooney: Does anybody have any questions that they want us to talk about specifically related to any part of this on any observations that you made or any of them are final uh I guess results from the map, which I can. 476 00:57:14.320 --> 00:57:21.220 Laura Mulrooney: put up again, or you can just see it's in the West, the closing, which is not showing up. 477 00:57:26.770 --> 00:57:29.980 Laura Mulrooney: So, this would be the final episode anyone have any questions they want us to talk about. 478 00:57:34.420 --> 00:57:39.760 Laura Mulrooney: If not, we have other things that we can do we've got about 30 minutes about 35 minutes left. 479 00:57:40.600 --> 00:57:45.850 Laura Mulrooney: We also if you'll have well at this point, I guess, say, if you have any questions if you had a chance to look through this before. 480 00:57:46.540 --> 00:57:52.570 Laura Mulrooney: we're happy to talk about any of the stops, we do have one last little activity for y'all to do but uh. 481 00:57:53.320 --> 00:58:00.580 Laura Mulrooney: We want to make sure that we have time to answer if you have any questions about anything that we've shown here either at this in person or about the other ones. 482 00:58:01.330 --> 00:58:11.950 Laura Mulrooney: And also, if you have questions later I encourage you to email me I think my email is included throughout here on throughout the STOP and also through GSA um I think it's included in the intro. 483 00:58:13.120 --> 00:58:13.510 Laura Mulrooney: But. 484 00:58:14.830 --> 00:58:20.020 Laura Mulrooney: yeah if nobody has any questions I can go to our next topic, but I don't want to rush y'all either. 485 00:58:25.870 --> 00:58:32.800 Laura Mulrooney: Okay, so I guess the next thing that will kind of talk about unless anyone has please ask questions cut me off go red head for it. 486 00:58:36.040 --> 00:58:43.780 Sandor Ricketts: I think if we had questions would ask you're actually doing a pretty good job with this whole thing so we're good I think we're good. 487 00:58:44.260 --> 00:58:44.770 Okay. 488 00:58:46.840 --> 00:58:49.870 Laura Mulrooney: So the next thing that we'll talk about a little bit is. 489 00:58:50.320 --> 00:58:58.300 Laura Mulrooney: Which is kind of what I included on the map his grandfather mountain, which is a window So this was not previously available to you, so you could not have looked at it beforehand. 490 00:58:59.350 --> 00:59:06.610 Laura Mulrooney: But we can kind of read through this together, and then we actually would like y'all to do a bit of said description writing. 491 00:59:08.860 --> 00:59:14.770 Laura Mulrooney: So let's see so the grandfather mountain window is this a series of. 492 00:59:16.240 --> 00:59:27.520 Laura Mulrooney: Various sized city sedimentary rocks there's a lot of everything from shales and slates all the way through there's some pretty massive conglomerates. 493 00:59:28.180 --> 00:59:36.100 Laura Mulrooney: So I encourage you to pull this up on your own to and look through but to start with there's a picture and let's start with this guy here. 494 00:59:37.720 --> 00:59:42.070 Laura Mulrooney: Too right, I said description of and so we're gonna. 495 00:59:43.360 --> 00:59:52.510 Laura Mulrooney: we're gonna write this too, so this will be kind of like our first exercise at the beginning, where we're going to give you the little prompting roll all right oh something together and then we'll come back and share it um. 496 00:59:53.560 --> 00:59:56.200 Laura Mulrooney: But, so I encourage you, this is a Meta sedimentary rock. 497 00:59:57.520 --> 01:00:09.160 Laura Mulrooney: But we're going to write a description of it, and so I look at the different one to notice the different class if you can figure out any sort of what's between them, if you can tell. 498 01:00:10.420 --> 01:00:16.150 Laura Mulrooney: What if you can write down colors if you had noticed any fossils which I don't think there's any facilities are pretty old rock. 499 01:00:19.390 --> 01:00:22.930 Laura Mulrooney: yeah so we're going to do a few of these descriptions we'll start with this one. 500 01:00:25.270 --> 01:00:32.110 Laura Mulrooney: yeah and we'll meet back and we'll go i'll be here, where we're going to write descriptions to and we'll share them in about. 501 01:00:33.520 --> 01:00:37.930 Laura Mulrooney: 710 minutes again, are there any questions before we start this. 502 01:00:41.920 --> 01:00:44.080 Laura Mulrooney: Okay we'll be here we're just going to be writing to. 503 01:03:06.610 --> 01:00:45.000 Sandor Ricketts: I learned one question. 504 01:00:45.001 --> 01:01:25.510 Laura Mulrooney: Okay, so let's talk about some of the things that could have been included in your description and some of the things that you probably can't tell, but how you would have actually figured them out in the field. 505 01:01:26.830 --> 01:01:37.630 Laura Mulrooney: So, to start with, and your description, you would have wanted to note the color of the class which you can see, like this is one here that's kind of like a grayish and there's some over here that are a little bit read on. 506 01:01:38.380 --> 01:01:53.590 Laura Mulrooney: You also would want to note the size and the size range and so in this picture all that really stands out are these bigger ones um if you were to look closer you probably would notice that there are some smaller ones that are borderline sand size that have filled in between. 507 01:01:55.900 --> 01:02:04.360 Laura Mulrooney: You would also wanted to make note of that you would want to note the actual shape and how round these grains are so I would say that. 508 01:02:04.930 --> 01:02:16.270 Laura Mulrooney: These are probably sub rounded sub angular balance, a little bit more angular but they're they're definitely not angular they're not something that looks like it's just a fracture they have some rounding to them. 509 01:02:18.550 --> 01:02:29.410 Laura Mulrooney: And then you also would want to note in this is one that gets a little bit more tricky because this isn't a Meta conglomerates into if things are showing any sort of elongation or if they're more cynical. 510 01:02:29.830 --> 01:02:38.830 Laura Mulrooney: And so, some of these grains are elongated but uh there are some I think there's some pictures later on, of like entire walls of this, I think. 511 01:02:41.890 --> 01:02:49.690 Laura Mulrooney: I think there are pictures of it yeah like there's just a lot, and so, if you have something like this that's been under as much stress and it's at this age. 512 01:02:50.350 --> 01:02:57.580 Laura Mulrooney: elongation is a little bit difficult to tell if it's something that is a feature of when it was deposited or if it's something that has been whether that way. 513 01:02:58.720 --> 01:03:02.530 Laura Mulrooney: or not, whether that has been metamorphose to that point um. 514 01:03:04.030 --> 01:03:10.180 Laura Mulrooney: If you were there in person, you would want to take note of the matrix, which is what is actually holding this together. 515 01:03:11.350 --> 01:03:18.790 Laura Mulrooney: And so, generally, the three matrix is that are the most expected, there are other things that it can be bummed out would be something that's going to be calcite. 516 01:03:19.750 --> 01:03:31.900 Laura Mulrooney: would have courts or some sort of hematite i'm from looking at this it's probably not hematite just because we would expect that to be a whole lot better and actually I do know that it's courts because i've read some papers about it. 517 01:03:33.100 --> 01:03:47.560 Laura Mulrooney: But that's something that you might not even be able to tell them the field um if you had hcl with you, you could put that on it, and if you weren't in an environment that that was going to be super common if it fits that might tell you something um. 518 01:03:48.610 --> 01:03:50.500 Laura Mulrooney: But it's not something that. 519 01:03:51.190 --> 01:04:00.310 Laura Mulrooney: If you're somewhere out West if you're in a desert environment, everything is going to fit and so that's not going to be something that's particularly useful but it's something where, if you were to cut an actual thin section of the area between. 520 01:04:00.610 --> 01:04:10.180 Laura Mulrooney: If it's courts or calcite you're going to see it it's going to be very clear at that point um another thing that you once again, you can't tell us from a picture, but as you would look at porosity. 521 01:04:10.870 --> 01:04:19.270 Laura Mulrooney: Which is how much space, there is actually between these grains which, once again, because this is a mega conglomerate there's not much for us the anymore. 522 01:04:19.990 --> 01:04:29.080 Laura Mulrooney: The courts has pretty much filled all of those but that's something that you would tell by putting an actual need pour a little bit of water on it and see how quickly it actually gets absorbed into the rock. 523 01:04:29.950 --> 01:04:47.050 Laura Mulrooney: And you also might have noticed, there are some courts veins throughout here on this entire area has a lot of course veins there's a lot of courts here a lot of solicit fluid, which is also kind of closes in that it's probably a silica that is holding the rock together. 524 01:04:49.510 --> 01:04:53.080 Laura Mulrooney: I will then also say, is once you actually make your observations. 525 01:04:54.010 --> 01:04:59.890 Laura Mulrooney: That allows you to make some sort of interpretation which you don't want to do until after you've made the observations. 526 01:05:00.280 --> 01:05:07.750 Laura Mulrooney: And so that's where it comes well if we have grains that are this large, these are some pretty big class, this is a good size conglomerate on. 527 01:05:08.380 --> 01:05:18.970 Laura Mulrooney: This is not something that you would expect to see on the beach you wouldn't go to Florida beach and sand size that are sand grains that are going to be like 10 centimeters big on. 528 01:05:20.050 --> 01:05:24.370 Laura Mulrooney: And so that's something where you can start to think about the actual deposition or environment um. 529 01:05:24.910 --> 01:05:35.560 Laura Mulrooney: it's also something that you would want to notice how how much sitting there is are all the grades, the exact same size or are there, as I mentioned previously, you might notice of their smaller grades that have filled in between. 530 01:05:36.400 --> 01:05:45.070 Laura Mulrooney: that's something that you would want to take note of and once again it's something that's a little difficult to different pictures, but we just want to get your thinking and practicing this so that when you do end up out. 531 01:05:45.580 --> 01:05:50.950 Laura Mulrooney: In the field and you're expected to make these observations it's not your first time trying to do it. 532 01:05:52.810 --> 01:05:56.170 Laura Mulrooney: So, are there any questions or anything that y'all want to talk about at this point. 533 01:05:58.660 --> 01:05:58.930 Sandor Ricketts: yeah. 534 01:06:00.970 --> 01:06:01.360 Laura Mulrooney: yeah. 535 01:06:02.050 --> 01:06:03.040 Sandor Ricketts: i'm a couple questions. 536 01:06:04.360 --> 01:06:07.960 Sandor Ricketts: Yet a photograph is kind of not the best to work with. 537 01:06:09.640 --> 01:06:11.380 Sandor Ricketts: Is it classroom matrix supported. 538 01:06:12.700 --> 01:06:13.930 Laura Mulrooney: It is matrix supported. 539 01:06:14.350 --> 01:06:15.340 Sandor Ricketts: This matrix supported. 540 01:06:16.090 --> 01:06:16.480 Yes. 541 01:06:18.550 --> 01:06:20.020 Sandor Ricketts: I was thinking more cost. 542 01:06:21.340 --> 01:06:32.530 Laura Mulrooney: yeah it is matrix supported so what that means, if anyone doesn't know is that means that the class are not all touching there are things between them better, making it so that if. 543 01:06:33.490 --> 01:06:41.710 Laura Mulrooney: If it were class supported, they would all be the class the matrix wouldn't actually be having any pressure on me wouldn't be holding things together well be holding these it wouldn't be. 544 01:06:43.870 --> 01:06:53.140 Laura Mulrooney: There would be matrix supported means that there is more space between the class for the matrix to take up room, because the simpler way to say it okay. 545 01:06:54.310 --> 01:06:54.970 Hazel Gordon: yeah yes. 546 01:06:55.060 --> 01:06:56.110 Laura Mulrooney: You have other questions. 547 01:06:56.410 --> 01:07:05.440 Hazel Gordon: yeah I have a question about the age and can we assume that most or possibly all conglomerates or freshwater to deposited. 548 01:07:06.790 --> 01:07:10.720 Laura Mulrooney: i'm not sure if they're fresh water deposit it or not, i'm. 549 01:07:11.410 --> 01:07:12.910 Hazel Gordon: around it so grounded. 550 01:07:13.450 --> 01:07:13.960 yeah. 551 01:07:15.670 --> 01:07:27.460 Sandor Ricketts: I i'm going to lean more towards freshwater deposits, because if you're looking at conglomerates you're going to be transporting material over usually in a river channel of some sort. 552 01:07:27.970 --> 01:07:42.190 Sandor Ricketts: yeah so that's what you guys do freshwater anything that's salt water is going to be deposited within the sea, but for that sort of a class size that would attract should have been transferred over large distance for it. 553 01:07:43.690 --> 01:07:48.430 Sandor Ricketts: for you to get smaller green so i'm thinking large large class. 554 01:07:49.450 --> 01:07:57.580 Sandor Ricketts: Sub rounded to some angle, as you said, to transport it a little distance probably during a flood event, based on the size of the Greens. 555 01:07:58.030 --> 01:08:11.320 Hazel Gordon: Yes, the class yeah taken from the West, which I live that's the assumption, I believe, but I was wondering about the age has anybody, you know gotten some kind of age with us. 556 01:08:12.040 --> 01:08:20.050 Laura Mulrooney: I think that it's debated um I think that I wanted to put an agent here and I found conflicting pieces of information. 557 01:08:21.220 --> 01:08:28.270
