WEBVTT 00:03.640 --> 00:06.100 we have eight recorded rock art sites 00:06.110 --> 00:07.832 at Fort Hunter Liggett . We're 00:07.832 --> 00:09.943 upgrading the documentation using new 00:09.943 --> 00:11.832 technologies that are available . 00:11.832 --> 00:13.554 They're also doing a condition 00:13.554 --> 00:15.610 assessment . So we're looking at how 00:15.610 --> 00:17.554 well this rock art is holding up . 00:17.554 --> 00:19.777 We're only seeing probably a fraction 5 00:19.777 --> 00:21.832 to 10% of the rock art that's left , 00:21.832 --> 00:24.054 which is why it's really critical right 00:24.054 --> 00:26.277 now to document what's left before it's 00:26.277 --> 00:28.388 gone forever . We've not surveyed all 00:28.388 --> 00:30.610 of it . We've only served about half of 00:30.610 --> 00:32.832 the installation , the type of rock and 00:32.832 --> 00:34.666 the location . The environmental 00:34.666 --> 00:36.832 setting that's here were able to start 00:36.832 --> 00:38.943 to put together a predictive model to 00:38.943 --> 00:41.110 look for other rock art locations . Is 00:41.110 --> 00:43.166 this one right here ? So this is his 00:43.166 --> 00:45.388 head , his arms come down here and then 00:45.388 --> 00:47.610 his lower house . But then all of these 00:47.610 --> 00:49.721 are other little tiny blue people all 00:49.721 --> 00:51.443 the way in here because it's a 00:51.443 --> 00:53.332 combination of charcoal and shell 00:53.332 --> 00:55.630 gypsum , so shell gypsum has crystals 00:55.630 --> 00:57.797 in it that when are reflected with the 00:57.797 --> 01:00.630 sun , somehow your eyes turn those into 01:00.630 --> 01:02.408 a bluish color with the kind of 01:02.408 --> 01:04.480 reflectivity of the shells , and so 01:04.480 --> 01:06.480 that's kind of a possibility of why 01:06.480 --> 01:08.536 they could appear blue . It's tucked 01:08.536 --> 01:10.647 back up in this con cavity , and it's 01:10.647 --> 01:12.813 very interesting that they try to hide 01:12.813 --> 01:15.091 them up in there , so it's not visible . 01:15.091 --> 01:17.091 When you're just walking across the 01:17.091 --> 01:17.080 land , you have to go up in to kind of 01:17.080 --> 01:19.920 see that most of these con cavities are 01:19.920 --> 01:22.640 covered with a black like black liken 01:22.640 --> 01:24.807 or black fungus , and they're painting 01:24.807 --> 01:26.862 kind of over that to show to make it 01:26.862 --> 01:29.029 pop . So if you're using a white paint 01:29.029 --> 01:31.196 on a black service , it shows a little 01:31.196 --> 01:33.251 bit more like a chalkboard and areas 01:33.251 --> 01:35.473 where there's not this fungus growing . 01:35.473 --> 01:34.850 They'll take a black charcoal and 01:34.850 --> 01:37.040 almost fill it in and then paint over 01:37.040 --> 01:39.151 it with white or red or another black 01:39.151 --> 01:40.873 so that it has that same black 01:40.873 --> 01:43.096 background to it . I've never seen that 01:43.096 --> 01:45.429 anywhere before . It's very interesting . 01:45.429 --> 01:47.540 It's very unique . There's not really 01:47.540 --> 01:49.596 an easy way to interpret rock art at 01:49.596 --> 01:51.596 all , so you don't want to say what 01:51.596 --> 01:53.929 somebody was thinking 502,000 years ago . 01:53.929 --> 01:55.929 There's something very unique about 01:55.929 --> 01:58.096 seeing a spiral . It's very magnetic , 01:58.096 --> 02:00.318 it's very attractive , and seeing it in 02:00.318 --> 02:02.484 white pigment is very interesting . It 02:02.484 --> 02:02.110 almost looks like it's a petroglyph , 02:02.110 --> 02:04.710 as if it's pecked into the surface 02:04.710 --> 02:06.766 itself . But it's actually made of a 02:06.766 --> 02:08.988 very white pigment over the centuries , 02:08.988 --> 02:11.180 has degraded in the sun and is quite 02:11.180 --> 02:13.640 faded . The rock art here , we believe , 02:13.640 --> 02:15.751 are associated with people that lived 02:15.751 --> 02:18.590 here year round from 1000 80 up till 02:18.880 --> 02:22.070 you know you're American Settlement and 02:22.070 --> 02:24.237 are still here . Today , the salad and 02:24.237 --> 02:26.014 D stretches an image processing 02:26.014 --> 02:28.181 software . It stands for D correlation 02:28.181 --> 02:30.126 stretching . So what it does is it 02:30.126 --> 02:32.292 takes the color , the color parts of a 02:32.292 --> 02:34.403 photo , and it stretches those colors 02:34.403 --> 02:36.920 to accentuate them in a certain way . 02:36.930 --> 02:39.152 So if you have a pictograph that's made 02:39.152 --> 02:40.986 of black or charcoal , there's a 02:40.986 --> 02:43.041 certain processing software that you 02:43.041 --> 02:45.208 use that pulls out the black and makes 02:45.208 --> 02:47.319 it much more visible or pulls out the 02:47.319 --> 02:49.374 red or the whites or the yellows and 02:49.374 --> 02:49.170 makes them much more visible . So if 02:49.170 --> 02:51.210 they're faded from 500 years of sun 02:51.210 --> 02:53.266 exposure and you run it through this 02:53.266 --> 02:55.543 program , it pops , it makes it really , 02:55.543 --> 02:57.766 really visible , and it's a really nice 02:57.766 --> 02:59.821 way to see things that you no longer 02:59.821 --> 03:01.932 see any more with the naked eye . I'm 03:01.932 --> 03:03.988 learning a lot about what makes this 03:03.988 --> 03:07.280 area so unique . If sites get damaged , 03:07.290 --> 03:09.690 vandalized or looted , that data is 03:09.690 --> 03:11.850 gone forever . So we've we've lost 03:11.850 --> 03:14.128 knowledge . It's not just about losing , 03:14.128 --> 03:16.239 you know the item . It's about losing 03:16.239 --> 03:18.461 the knowledge associated with it . It's 03:18.461 --> 03:20.517 part of America's history . It's for 03:20.517 --> 03:22.683 the benefit of all Americans . Uh , so 03:22.683 --> 03:24.628 we have a responsibility here as a 03:24.628 --> 03:26.906 federal agency , Department of Defense . 03:26.906 --> 03:28.628 You know , here , on this army 03:28.628 --> 03:30.683 installation , we take seriously our 03:30.683 --> 03:32.794 responsibility to be good stewards of 03:32.794 --> 03:33.960 the cultural resources .
