WEBVTT 00:01.301 --> 00:03.470 align:start We're now heading out of New Mexico towards. 00:03.503 --> 00:05.271 align:start Hidden in the Four Corners region 00:05.305 --> 00:08.341 align:start are markers from ancient solar calendars. 00:08.375 --> 00:12.145 align:start Seeing these relics on just the right day, 00:12.178 --> 00:15.515 align:start offers glimpses of the artistic life 00:15.548 --> 00:18.251 align:start of some of the first Americans. 00:18.284 --> 00:20.387 align:start The edge of this rock can be aligned with 00:20.420 --> 00:23.556 align:start those standing stones that we've seen. like Pueblo Bonito. 00:23.590 --> 00:25.959 align:start You look at the rock there. 00:25.992 --> 00:28.328 align:start Of course getting there can be half the fun. 00:31.564 --> 00:33.767 align:start Major funding for The Desert       Speaks was provided by 00:33.800 --> 00:36.803 align:start the Kemper and Ethel Marley Foundation. 00:36.836 --> 00:39.472 align:start Additional funding was provided by 00:39.472 --> 00:43.376 align:start Desert Program Partners and by Arizona State Parks. 01:16.209 --> 01:18.244 align:start Living in the open and coast of the land 01:18.278 --> 01:21.047 align:start like the ancient Anasazi, makes people aware 01:21.081 --> 01:24.751 align:start of the power of the sun; its behavior, its seasons 01:24.784 --> 01:29.789 align:start and their affect on our lives. 01:29.823 --> 01:32.058 align:start The Anasazi were skilled observers of celestial events 01:32.092 --> 01:34.527 align:start and became some of the 01:34.527 --> 01:38.932 align:start most sophisticated ancient astronomers. 01:38.965 --> 01:41.734 align:start I'm joining a group from Crow Canyon Archaeological Center 01:41.768 --> 01:43.970 align:start in Colorado in search of what's left 01:44.003 --> 01:49.642 align:start of their cosmological record. 01:51.978 --> 01:54.914 align:start The Four Corners area is the heart of the Anasazi culture 01:54.948 --> 01:59.486 align:start including our starting point along the San Juan River. 01:59.519 --> 02:02.155 align:start To help us understand what we're seeing our veteran trip leader 02:02.188 --> 02:04.224 align:start and renowned archaeologist Gwinn Vivian 02:04.257 --> 02:09.496 align:start and lifelong astronomer John Fountain. 02:09.529 --> 02:13.933 align:start This trip is essentially designed to bring people 02:13.967 --> 02:19.005 align:start to places where we know that prehistoric peoples 02:19.038 --> 02:22.342 align:start recorded movements of the sun. 02:22.375 --> 02:28.615 align:start June 21st, Summer Solstice. 02:28.648 --> 02:32.118 align:start The sun's straight up, hot and blazing. 02:32.152 --> 02:35.555 align:start So it's a pretty tough time of the year, 02:35.588 --> 02:38.825 align:start maybe the hottest day. 02:38.858 --> 02:40.326 align:start We've got ten hours of sun on the river. 02:40.360 --> 02:42.996 align:start But there's hope. 02:43.029 --> 02:45.565 align:start Cause when the solstice come, the old timers knew 02:45.598 --> 02:51.538 align:start and maybe we know the rains can't be too far away. 02:51.571 --> 03:02.048 align:start The San Juan is a desert canyon river and it sometimes 03:02.081 --> 03:05.885 align:start got treacherous deep places and bad currents. 03:05.919 --> 03:07.720 align:start Sometimes you have to take a risk in life 03:07.754 --> 03:14.127 align:start and so I'm going to do it. 03:14.160 --> 03:17.864 align:start There it is, the San Juan at its deepest. 03:17.897 --> 03:19.832 align:start If too many people drink out of it at the same time, 03:19.866 --> 03:25.738 align:start the level goes way down. 03:25.772 --> 03:30.376 align:start The first stop on our two-day river trip leads us to 03:30.410 --> 03:38.384 align:start a panel of Anasazi rock art and plenty of speculation. 03:38.418 --> 03:40.486 align:start The images are up high now and it's most likely 03:40.520 --> 03:43.189 align:start that whoever did them was standing on the ground. 03:43.223 --> 03:44.924 align:start This is eight hundred years of erosion. 03:44.958 --> 03:47.594 align:start It's eroded the slopes down. 03:47.627 --> 03:50.296 align:start Sometimes you see figures with a little bird or a dog 03:50.296 --> 03:53.132 align:start or something on their shoulder like a spirit helper. 03:53.166 --> 03:55.535 align:start So there's various things about this panel 03:55.568 --> 03:59.539 align:start that suggests that these are Shamen. 03:59.572 --> 04:01.507 align:start These are not stick figures at all. 04:01.541 --> 04:03.977 align:start You can see the arms, the legs, the hands, 04:04.010 --> 04:08.548 align:start fingers on the hands and your don't see that 04:08.581 --> 04:11.718 align:start practically at all in later human figures that 04:11.751 --> 04:16.789 align:start appear in Anasazi rock art. 04:16.823 --> 04:18.258 align:start There's a yucca plant. 04:18.291 --> 04:21.527 align:start There's some bighorn sheep. 04:21.561 --> 04:24.964 align:start There's some corn plants, more of those lobe circles. 04:24.998 --> 04:27.000 align:start There's quite an assortment of things. 04:27.033 --> 04:29.435 align:start There's an ET figure that proved that the 04:29.469 --> 04:34.374 align:start extra-terrestrials were here in Basketmaker times. 04:34.407 --> 04:36.075 align:start Does that look like ET to you up there? 04:36.109 --> 04:39.379 align:start No, but he's got the long arms. 04:39.412 --> 04:41.581 align:start Sometimes we don't want something to look too human. 04:41.614 --> 04:42.615 align:start Right. 04:42.649 --> 04:45.918 align:start Exactly. 04:45.952 --> 04:48.821 align:start One of the ways to translate the freedom in a graphic image 04:48.855 --> 04:51.891 align:start would be floating upside down. 04:51.924 --> 04:54.027 align:start There's multiple kinds of ways to explain these 04:54.060 --> 04:56.529 align:start but they all come back to some kind of trance state. 04:56.562 --> 05:00.800 align:start Various archaeologists have looked at those figures 05:00.833 --> 05:04.003 align:start and felt that they represented some kind of 05:04.037 --> 05:07.540 align:start out-of-this-world kind of being that was 05:07.573 --> 05:12.378 align:start important to their culture. 05:14.447 --> 05:16.816 align:start Well at about forty-five minutes from here 05:16.849 --> 05:19.352 align:start to where we will walk over to River House. 05:19.385 --> 05:28.194 align:start On this stretch of the San Juan, 05:28.227 --> 05:30.797 align:start the walls are pretty far apart. 05:30.830 --> 05:33.533 align:start The river tends to meander, move back and forth. 05:33.566 --> 05:36.803 align:start It brings a lot of silt and drops it as it meanders. 05:36.836 --> 05:40.073 align:start That makes for fertile fields and the Anasazi, 05:40.106 --> 05:42.375 align:start the people before 'em, found it was great 05:42.408 --> 05:48.514 align:start for raising corns and beans and squash. 05:48.548 --> 05:51.851 align:start So then we'll be able to take a short walk up to River House. 05:51.884 --> 05:57.590 align:start From the cool river it's a half mile hike through the heat. 05:57.623 --> 05:59.959 align:start It's the largest archaeological site 05:59.992 --> 06:04.664 align:start on the San Juan River. 06:04.697 --> 06:07.867 align:start River House was a habitation site. 06:07.900 --> 06:11.037 align:start We find evidence of storage units here. 06:11.070 --> 06:14.173 align:start We find kivas and we find a good number of rooms. 06:14.207 --> 06:16.676 align:start All of which come together and tell us that 06:16.709 --> 06:20.947 align:start we are dealing with a habitation site here. 06:20.980 --> 06:23.216 align:start .the palm of the hand was painted with those designs. 06:23.249 --> 06:25.251 align:start The ceramics at River House and the architecture 06:25.284 --> 06:29.555 align:start at River House say 'Mesa Verde.' 06:29.589 --> 06:32.492 align:start Basically this reflects the fact that these rooms, 06:32.525 --> 06:37.730 align:start the kivas, were built by Mesa Verde people. 06:37.764 --> 06:42.969 align:start Probably a group of related families occupied River House 06:43.002 --> 06:47.006 align:start in which you have clans which come together, 06:47.039 --> 06:50.610 align:start individual clans are responsible for different ceremonies 06:50.643 --> 06:53.346 align:start during the year, the whole idea being that 06:53.379 --> 06:56.582 align:start the bringing together of those ceremonies provides 06:56.616 --> 07:02.188 align:start a benefit for the entire community. 07:02.221 --> 07:04.090 align:start The panels at Butler Wash are petroglyphs 07:04.123 --> 07:06.392 align:start which are pecked into the cliff. 07:06.426 --> 07:11.397 align:start We have also pictographs including a red and white 07:11.431 --> 07:14.333 align:start wavy figure that may be a snake figure. 07:14.367 --> 07:18.104 align:start And then behind us a whole set of white hands. 07:18.137 --> 07:24.577 align:start We see here a representation of the idea of the sky. 07:24.610 --> 07:29.081 align:start The people have made dots and little plus signs on 07:29.115 --> 07:32.885 align:start the overhang to represent the idea of the sky. 07:32.885 --> 07:35.721 align:start Not actual constellations because we know what 07:35.755 --> 07:37.790 align:start constellations were important to them and we 07:37.824 --> 07:39.592 align:start do not find those here at all. 07:39.625 --> 07:42.395 align:start We find no match with the sky. 07:42.428 --> 07:44.897 align:start We do find a cluster of spots up there that is suggestive 07:44.897 --> 07:47.099 align:start of the Pleiades which we know to have been 07:47.133 --> 07:52.138 align:start very important to them though. 07:52.171 --> 07:54.574 align:start Throughout the southwest and even into Mesoamerica 07:54.607 --> 07:57.109 align:start the sky serpent is very important and he's often 07:57.143 --> 08:00.713 align:start represented as having ? or horns moving upward 08:00.746 --> 08:03.649 align:start into the sky and so is quite consistent with this 08:03.683 --> 08:13.392 align:start interpretation of a planetarium ceiling. 08:13.426 --> 08:15.127 align:start The rest of the stops on our trip 08:15.161 --> 08:17.196 align:start don't involve wading through rivers. 08:17.230 --> 08:19.565 align:start Fifty miles east of our take out on the San Juan 08:19.565 --> 08:22.435 align:start is Hovenweep National Monument, not too far from 08:22.468 --> 08:24.570 align:start the national park at Mesa Verde for which 08:24.570 --> 08:29.408 align:start the ancient inhabitants are now named. 08:29.442 --> 08:31.410 align:start Here, a few days after the solstice, if we're lucky, 08:31.444 --> 08:33.679 align:start we'll see how the rays of the sun intersect 08:33.713 --> 08:40.620 align:start the mystical Anasazi spiral. 08:40.653 --> 08:44.290 align:start My guess is they selected sites like this so that they could 08:44.323 --> 08:49.362 align:start bring a large crowd out and tell a story and have an 08:49.395 --> 08:54.901 align:start audio-visual, a multi-media presentation. 08:54.934 --> 08:57.169 align:start And if it was cloudy on the important day, 08:57.203 --> 08:59.372 align:start they could bring the folks back the next day 08:59.405 --> 09:03.075 align:start and still show the same event. 09:03.109 --> 09:05.745 align:start We have many examples of solar markers that are not 09:05.778 --> 09:08.314 align:start terribly precise but are in a very public area 09:08.347 --> 09:10.683 align:start where lots of people can see, where the acoustics 09:10.716 --> 09:14.554 align:start are fairly good, but some of the more precise ones 09:14.587 --> 09:17.223 align:start are tucked away in places where only one or two people 09:17.256 --> 09:27.767 align:start can see them at a time. 09:27.800 --> 09:29.902 align:start Hovenweep not only has solstice markers but some 09:29.936 --> 09:37.343 align:start mighty fine architecture as well. 09:37.376 --> 09:41.347 align:start This is a Hovenweep collection of tower sites 09:41.380 --> 09:46.452 align:start that are representative of a probable movement of 09:46.485 --> 09:49.822 align:start Mesa Verde peoples from the east. 09:49.855 --> 09:53.225 align:start These people were Ancestral Puebloans or 09:53.259 --> 09:55.861 align:start some people called them Anasazi. 09:55.895 --> 10:01.334 align:start Tree ring dates put them here from about 1230 to 1280. 10:01.367 --> 10:06.806 align:start Probably they were here up until about 1300. 10:06.839 --> 10:09.041 align:start Archaeologists have really argued about what function 10:09.041 --> 10:11.577 align:start these buildings may have served to the 10:11.611 --> 10:14.547 align:start pre-historic people that lived here. 10:14.580 --> 10:17.583 align:start There's some fairly good evidence that they were located 10:17.617 --> 10:21.621 align:start at the heads of canyons for defense of springs. 10:21.654 --> 10:23.789 align:start The middle 1200s was a period of time when 10:23.823 --> 10:26.692 align:start things were getting rather dry. 10:26.692 --> 10:29.695 align:start Springs were a very important resource. 10:29.695 --> 10:33.599 align:start Here on the mesas of the high deserts of the southwest 10:33.633 --> 10:36.068 align:start there's only about eight to ten inches of rainfall of year. 10:36.068 --> 10:39.472 align:start That's not much to make a tree grow. 10:39.505 --> 10:42.575 align:start There is one tree though that does real well here. 10:42.608 --> 10:48.748 align:start And that's the ever present, very common, Juniper tree. 10:48.781 --> 10:50.716 align:start Not only is the sweet-smelling Juniper wood 10:50.716 --> 10:53.486 align:start the finest firewood anywhere, but the bark 10:53.519 --> 10:57.523 align:start which is easily pulled off the tree could be twisted 10:57.556 --> 11:01.861 align:start and made into rope, into cord, into thread, 11:01.894 --> 11:05.931 align:start into string and from this ? 11:05.965 --> 11:09.101 align:start Juniper bark, garments still exist today that 11:09.101 --> 11:14.473 align:start were woven hundreds of years ago. 11:14.507 --> 11:16.575 align:start These people had a series of rituals, much as we do, 11:16.609 --> 11:19.345 align:start that changed through the years. 11:19.378 --> 11:22.214 align:start Religious ceremonies that were performed at different times 11:22.248 --> 11:27.420 align:start of the year and knowing when the sun was in different positions 11:27.453 --> 11:32.391 align:start during the year helped them to mark those times of the year 11:32.425 --> 11:37.797 align:start when those ceremonies should be carried out. 11:37.830 --> 11:40.399 align:start In many places in the southwest we have structures 11:40.433 --> 11:43.369 align:start with apertures or holes like this which allow 11:43.402 --> 11:46.839 align:start the morning sunlight to shine through to a distinctive place 11:46.872 --> 11:50.810 align:start on the far wall at the solstices. 11:50.843 --> 11:54.213 align:start Here at Hovenweep Castle we have the opposite situation 11:54.246 --> 12:00.486 align:start where sunlight shines through at sunset. 12:07.093 --> 12:10.029 align:start I think that archaeologists have tended to possibly 12:10.062 --> 12:14.533 align:start over exaggerate the relevance of some of the observations 12:14.567 --> 12:21.006 align:start that archaeologists have made. 12:21.040 --> 12:23.275 align:start We can't get into the minds of the people who lived 12:23.309 --> 12:28.214 align:start in the past and a lot of this is based upon our supposition 12:28.247 --> 12:29.849 align:start as to what may have happened in the past and some of it 12:29.882 --> 12:33.786 align:start may be mere coincidence. 12:33.819 --> 12:35.888 align:start Just twenty miles to the northwest of Hovenweep is 12:35.921 --> 12:39.992 align:start Montezuma Canyon, home of the Cold Bed Ruin. 12:40.025 --> 12:42.328 align:start I was hoping to see impressive architecture 12:42.361 --> 12:44.964 align:start and cliff dwellings, as they were at one time. 12:44.997 --> 12:49.635 align:start Instead it looked like scattered piles of rocks. 12:49.668 --> 12:53.939 align:start Fortunately, Gwinn and John have done their homework. 12:53.973 --> 12:56.175 align:start I think that probably some of you as we've walked up here 12:56.208 --> 12:58.711 align:start have thought that there really isn't any order to it. 12:58.744 --> 13:02.748 align:start In fact, these buildings were very well laid out and defined. 13:02.782 --> 13:04.950 align:start And this is one good example where you can see the outer wall 13:04.984 --> 13:10.055 align:start of this complex of ruins and kivas. 13:10.089 --> 13:12.725 align:start The deep depression over there is a kiva. 13:12.758 --> 13:15.594 align:start Whether or not this represented a certain segment of the society 13:15.628 --> 13:19.098 align:start that was living here, we really can't tell. 13:19.131 --> 13:22.501 align:start But it's a line of evidence that archaeologists could follow 13:22.535 --> 13:26.539 align:start and look for differences in ceramic production between this 13:26.572 --> 13:29.642 align:start group of ruins and the group of ruins that we've 13:29.675 --> 13:35.614 align:start just come over as we've walked up here. 13:35.648 --> 13:37.183 align:start Some of these pillars are leaning and some have 13:37.216 --> 13:39.552 align:start actually fallen over. 13:39.585 --> 13:43.189 align:start Yes, but if one measures along the base of them, 13:43.222 --> 13:45.958 align:start one finds a remarkably north-south alignment. 13:45.991 --> 13:48.928 align:start So this suggests an astronomical use. 13:48.961 --> 13:51.030 align:start They could have been incorporated into the 13:51.063 --> 13:54.099 align:start architecture of the nearby ruins but we have 13:54.133 --> 13:57.570 align:start an indication that they might have been used to measure 13:57.603 --> 14:05.911 align:start the position of the sun at different times of the year. 14:05.911 --> 14:07.313 align:start There's more going on here than just an 14:07.346 --> 14:11.417 align:start alignment of these rocks. 14:11.450 --> 14:14.820 align:start We have a gun site here that allows us to line up 14:14.854 --> 14:18.824 align:start the position of the sun at various times of the year. 14:18.858 --> 14:21.093 align:start So here we must be looking west. 14:21.126 --> 14:22.828 align:start That's right. 14:22.862 --> 14:25.297 align:start The edge of this rock can be aligned with 14:25.297 --> 14:28.534 align:start those standing stones that we've seen and those would 14:28.567 --> 14:34.340 align:start mark certain times of the year when the sun is low in the sky. 14:34.373 --> 14:36.041 align:start And you believe that? 14:36.075 --> 14:39.311 align:start Well, I believe that that's a very strong possibility 14:39.311 --> 14:44.083 align:start given that those stones are accurately aligned to the north. 14:44.116 --> 14:45.551 align:start But they could be part of the architecture 14:45.584 --> 14:48.587 align:start of the ruins behind it. 14:48.621 --> 14:50.489 align:start So how would you verify this? 14:50.522 --> 14:52.691 align:start Well, first we take simple compass measurements 14:52.725 --> 14:56.762 align:start and if this looks like it's productive, 14:56.795 --> 14:59.565 align:start then we do a survey to see if the directions 14:59.598 --> 15:01.800 align:start that we're looking in are consistent with the sun 15:01.834 --> 15:05.671 align:start at various times of the year. 15:05.704 --> 15:07.172 align:start That'll tell you whether they knew what they were doing here. 15:07.206 --> 15:09.141 align:start That's right. 15:09.174 --> 15:12.011 align:start The problem that we have is that these stones are old 15:12.044 --> 15:13.646 align:start and have tilted and we don't know exactly how 15:13.679 --> 15:18.817 align:start they were placed originally. 15:18.851 --> 15:20.619 align:start The Coal Bed Ruin has a number of examples of 15:20.653 --> 15:23.155 align:start really good Mesa Verde pottery. 15:23.188 --> 15:25.391 align:start This is a Black on White. 15:25.424 --> 15:27.626 align:start You really know it's Mesa Verde Black on White because 15:27.660 --> 15:30.429 align:start of the black marks on the top of the rim. 15:30.462 --> 15:32.131 align:start It probably, because it's so white on the background, 15:32.164 --> 15:34.066 align:start was produced at Mesa Verde. 15:34.099 --> 15:36.802 align:start This is what was probably produced locally because 15:36.835 --> 15:40.706 align:start the background is gray with the Black on Gray. 15:40.739 --> 15:42.574 align:start They also were producing the cooking ware 15:42.608 --> 15:45.177 align:start such as indented corrugated. 15:45.210 --> 15:47.413 align:start There's another example of the indented corrugated 15:47.446 --> 15:50.749 align:start and there's a lot here. 15:50.783 --> 15:53.585 align:start Here's yet one more of the Mesa Verde Black on White 15:53.619 --> 15:55.988 align:start that's become pretty much faded. 15:56.021 --> 15:58.290 align:start So you find this whole range of this type of ceramics 15:58.324 --> 16:03.696 align:start but they all are Mesa Verde Black on White. 16:03.729 --> 16:06.265 align:start In addition to the ceramics that we find here, 16:06.298 --> 16:08.300 align:start these people were producing a lot of lithic stone tools 16:08.334 --> 16:10.502 align:start out of a kind of material that's local, 16:10.536 --> 16:14.139 align:start it's called Brushy Basin chert or Morrison chert. 16:14.173 --> 16:16.075 align:start And what's really intriguing is this material 16:16.108 --> 16:22.381 align:start which is mined here was traded to Chaco. 16:22.414 --> 16:23.816 align:start One hundred and fifty miles away in New Mexico 16:23.849 --> 16:26.919 align:start is Chaco Canyon. 16:26.952 --> 16:29.722 align:start This was the apex of Anasazi culture with a collection 16:29.755 --> 16:33.625 align:start of apartments, observation sites, roads connecting outlying 16:33.659 --> 16:36.695 align:start villages and, above all, a demonstration of 16:36.729 --> 16:44.803 align:start engineering accomplishments and astronomical achievements. 16:44.837 --> 16:46.972 align:start We have over three hundred solar markers documented 16:47.006 --> 16:49.875 align:start throughout the southwest marking the equinoxes, 16:49.908 --> 16:54.646 align:start the solstices and the cross quarter day, 16:54.680 --> 16:58.751 align:start the day halfway in between the equinox and the solstice. 16:58.784 --> 17:03.722 align:start In Chaco we probably have almost more evidence for 17:03.756 --> 17:08.293 align:start that kind of marking of the movement of the sun 17:08.327 --> 17:11.597 align:start than any other single well known archaeological site 17:11.630 --> 17:13.832 align:start in the southwest. 17:13.866 --> 17:17.936 align:start The Anasazi people are the ancestors of Puebloan peoples 17:17.970 --> 17:22.307 align:start who we find today in villages such as Zuni, in New Mexico, 17:22.341 --> 17:27.746 align:start the Hopi Pueblos in Arizona and the Rio Grande hill peoples. 17:27.780 --> 17:33.185 align:start The primary form of subsistence was as farmers. 17:33.218 --> 17:37.790 align:start They were always hunting. 17:37.823 --> 17:39.458 align:start They were always gathering. 17:39.491 --> 17:44.296 align:start But I can say that most, sixty percent or seventy percent 17:44.329 --> 17:48.667 align:start of their food they depended upon being farmers. 17:48.700 --> 17:51.336 align:start Because great houses have a lot of standing architecture, 17:51.370 --> 17:53.705 align:start that is the walls are standing and you can see them, 17:53.739 --> 17:56.575 align:start we have much better evidence in those buildings 17:56.608 --> 18:00.712 align:start for using buildings to mark different phases 18:00.746 --> 18:03.816 align:start of the movement of the sun. 18:03.849 --> 18:07.052 align:start We're standing right next to the southern most wall 18:07.086 --> 18:10.289 align:start of the great house Pueblo Bonito. 18:10.322 --> 18:15.127 align:start And it forms an east-west alignment with great precision 18:15.160 --> 18:19.164 align:start and then right down the middle of the great house 18:19.164 --> 18:24.036 align:start we have a wall that goes exactly north-south. 18:24.069 --> 18:26.004 align:start And so this building is very carefully aligned 18:26.038 --> 18:29.508 align:start along the cardinal directions. 18:29.541 --> 18:32.077 align:start This is consistent with the pre-occupation that Chacoans 18:32.111 --> 18:38.450 align:start seem to have with directionality. 18:38.484 --> 18:40.652 align:start In the southeast corner of Pueblo Bonito we have an unusual 18:40.686 --> 18:42.855 align:start architectural feature which points 18:42.888 --> 18:47.593 align:start toward the winter solstice. 18:47.626 --> 18:49.761 align:start Whether it was a true observation point or not 18:49.795 --> 18:51.730 align:start is open to question because we don't know whether 18:51.763 --> 18:55.467 align:start there was a wall obstructing it. 18:55.501 --> 18:58.437 align:start But certainly it points in that direction but it would not 18:58.470 --> 19:04.076 align:start make a precise device for observing the event. 19:04.109 --> 19:05.444 align:start The winter solstice represents the end 19:05.477 --> 19:07.913 align:start of a cycle of the sun's motion. 19:07.946 --> 19:11.116 align:start It's a metaphor for death. 19:11.150 --> 19:14.720 align:start By the same token, it's a metaphor for rebirth 19:14.753 --> 19:18.257 align:start because from now on the sun is rising higher in the sky, 19:18.290 --> 19:20.192 align:start later on the plants will come back 19:20.225 --> 19:26.198 align:start and a new cycle of life begins. 19:26.231 --> 19:28.300 align:start Originally I think archaeologists thought that 19:28.333 --> 19:33.138 align:start noting the pre-historic documenting of the solstices, 19:33.172 --> 19:34.907 align:start both the summer and the winter solstices, 19:34.940 --> 19:38.277 align:start was related to their planting cycles. 19:38.310 --> 19:40.145 align:start That they used this as a way of telling them when 19:40.179 --> 19:43.615 align:start they should plant in the spring. 19:43.615 --> 19:45.984 align:start More archaeologists now feel that it may not have been 19:46.018 --> 19:48.287 align:start related that closely to the planting cycle but was important 19:48.320 --> 19:50.989 align:start for carrying out a series of rituals which were 19:51.023 --> 19:54.193 align:start scheduled throughout the year. 19:54.226 --> 19:58.330 align:start They were using particularly the sun to develop 19:58.363 --> 20:01.166 align:start a calendar to remind themselves of when 20:01.200 --> 20:09.241 align:start they should be carrying out these rituals. 20:09.274 --> 20:11.910 align:start People have been in Chaco Canyon for at least two thousand years. 20:11.944 --> 20:15.347 align:start They came from various points around the San Juan Basin. 20:15.380 --> 20:18.784 align:start They came from the south, they came from the north. 20:18.817 --> 20:24.223 align:start We see them occupying the canyon until the middle to the late 20:24.256 --> 20:26.158 align:start 1100s at which point there's a general exodus 20:26.191 --> 20:28.760 align:start out of the canyon. 20:28.794 --> 20:32.831 align:start It was almost certainly abandoned because of a drought. 20:32.864 --> 20:36.835 align:start And it simply became ultimately too dry for them 20:36.868 --> 20:41.373 align:start to farm successfully. 20:41.406 --> 20:43.442 align:start When you're in Chaco, normally if you're on the north side 20:43.475 --> 20:45.043 align:start of the canyon, what you're gonna be pretty much seeing 20:45.077 --> 20:47.479 align:start are the great houses. 20:47.512 --> 20:49.982 align:start If you cross to the south side, you'll see the great kiva 20:50.015 --> 20:55.754 align:start of Casa Rinconara and a number of small house sites. 20:55.787 --> 20:59.057 align:start The light is coming down from the top and it's 20:59.091 --> 21:06.031 align:start going to shine right into that little square right over there. 21:06.064 --> 21:08.500 align:start They either accidentally got it just right or they created 21:08.533 --> 21:12.638 align:start the alignment in the first place. 21:12.671 --> 21:14.539 align:start It's a perfect illustration of the basic technique 21:14.573 --> 21:16.842 align:start for sun watchingóbringing the sun indoors 21:16.875 --> 21:19.211 align:start and then being able to mark it on the opposite wall 21:19.244 --> 21:21.880 align:start and this isn't unique to the southwest by any means. 21:21.913 --> 21:24.483 align:start So it has the power, it has that kind of energy. 21:24.516 --> 21:27.219 align:start People come and see it, they're impacted by it 21:27.252 --> 21:29.921 align:start and at least in part when they would create such things, 21:29.955 --> 21:32.624 align:start that's a part of the reason. 21:32.658 --> 21:35.193 align:start It's like an artistic expression of our true relationship 21:35.227 --> 21:37.195 align:start with the rest of the world. 21:37.229 --> 21:39.398 align:start And so it's supposed to have a powerful impact and this does. 21:39.431 --> 21:40.666 align:start Whether it was intentional or not 21:40.699 --> 21:46.805 align:start is almost beside the point. 21:46.838 --> 21:50.008 align:start They're amazing the way they angled everything. 21:50.042 --> 21:53.945 align:start They had it all figured out. 21:53.979 --> 21:57.115 align:start You get a feeling here of what used to happen. 21:57.149 --> 22:03.922 align:start So yeah, there was some connection. 22:03.955 --> 22:06.391 align:start This is often related to the idea of the sun 22:06.391 --> 22:10.062 align:start impregnating the earth, an expression of appreciation 22:10.095 --> 22:12.731 align:start for the fertility of the earth or perhaps hoping for 22:12.764 --> 22:17.502 align:start improved fertility in the future. 22:17.536 --> 22:20.305 align:start And how better could you memorialize the sun, 22:20.339 --> 22:26.645 align:start pay homage to the sun, than using its light in a special way 22:26.678 --> 22:29.448 align:start during your ceremonies. 22:29.481 --> 22:32.150 align:start They had the sophistication to do it. 22:32.184 --> 22:34.619 align:start Whether this was just a coincidence, 22:34.653 --> 22:37.723 align:start what we observed today, or whether it was carefully planned 22:37.756 --> 22:45.163 align:start and there was an aperture out here, we don't know. 22:45.197 --> 22:48.066 align:start This morning we'll be taking a walk up the canyon 22:48.100 --> 22:53.839 align:start to Penasco Blanco to look at the super nova pictograph. 22:53.872 --> 22:57.442 align:start The Chacoans were sophisticated architects 22:57.442 --> 23:00.345 align:start and accomplished astronomers. 23:00.379 --> 23:03.749 align:start But they are also human beings with time on their hands. 23:03.782 --> 23:06.718 align:start And they liked to carve in this soft sandstone. 23:06.752 --> 23:08.987 align:start Some of these symbols are probably 23:09.020 --> 23:11.123 align:start very important culturally for them. 23:11.156 --> 23:13.024 align:start Others are just doodlings that may have come along 23:13.058 --> 23:16.094 align:start the last thousand years. 23:16.128 --> 23:18.096 align:start If we look carefully, we can probably see what 23:18.130 --> 23:22.401 align:start they had on their minds. 23:22.434 --> 23:24.836 align:start A hand, crescent, star. 23:24.836 --> 23:25.904 align:start Okay. 23:25.937 --> 23:27.305 align:start All right. 23:27.339 --> 23:29.207 align:start I have little comment on a hand except that this 23:29.241 --> 23:31.843 align:start is a way of personalizing a drawing. 23:31.843 --> 23:35.013 align:start But what we're seeing here is an image of the crescent moon, 23:35.046 --> 23:38.517 align:start which is very rare in rock art. 23:38.550 --> 23:41.086 align:start We see next to it a ten-pointed star which we believe 23:41.119 --> 23:44.456 align:start is a representation of the crab super nova 23:44.489 --> 23:48.126 align:start when it exploded in 1054. 23:48.160 --> 23:52.431 align:start We know the moon, crescent moon was very close at that time. 23:52.464 --> 23:55.801 align:start It is also possible that it was a long period comet 23:55.834 --> 23:58.870 align:start which was only visible in the northern hemisphere. 23:58.870 --> 24:00.906 align:start There is precedent for this sort of thing. 24:00.939 --> 24:03.175 align:start But we can't say what it was with certainty. 24:03.208 --> 24:07.112 align:start Super nova events are really very rare events. 24:07.145 --> 24:10.015 align:start They happen only once every couple of hundred years 24:10.048 --> 24:12.918 align:start and certainly people who were sky watchers, 24:12.951 --> 24:15.153 align:start as we know these people were, 24:15.187 --> 24:20.792 align:start would have taken note of it immediately. 24:20.826 --> 24:27.466 align:start The millennia of human habitation of the high desert 24:27.499 --> 24:30.869 align:start of the southwest culminated in four hundred years 24:30.902 --> 24:36.341 align:start of dazzling art, architecture and astronomy. 24:36.374 --> 24:39.678 align:start An ongoing drought drove the people away, 24:39.711 --> 24:44.449 align:start ended their accomplishment and studies by the astronomers. 24:44.483 --> 24:46.852 align:start We can only speculate what these scientists knew 24:46.885 --> 24:51.289 align:start but it was a result, not of miracle or mystery, 24:51.323 --> 24:55.760 align:start but of decades and decades of careful studies of the sun 24:55.794 --> 24:58.463 align:start and observations of the heavens above. 25:00.999 --> 25:09.374 align:start The colonial city of Alamos in northwest Mexico 25:09.407 --> 25:13.478 align:start has plenty to offer visitors. 25:13.512 --> 25:16.748 align:start There's Spanish legacy and rich natural treasures. 25:16.781 --> 25:19.317 align:start Perhaps most interesting, the traditional knowledge 25:19.351 --> 25:23.855 align:start from some of the area's longest residents, the Mayos. 25:23.889 --> 25:27.025 align:start Next time on The Desert Speaks. 26:00.392 --> 26:02.794 align:start Major funding for The Desert       Speaks was provided by 26:02.827 --> 26:06.064 align:start the Kemper and Ethel Marley Foundation. 26:06.097 --> 26:08.466 align:start Additional funding was provided by
