WEBVTT 00:03.570 --> 00:09.209 align:start Peru is home not only to majestic landscapes, 00:09.209 --> 00:14.948 align:start scenic roads, tasty delights, 00:14.948 --> 00:19.586 align:start and the grandfather of all tall cacti, 00:19.586 --> 00:26.893 align:start it also happens to be home of the little known Amazon Desert. 00:30.597 --> 00:32.098 align:start Funding for         The Desert Speaks 00:32.132 --> 00:34.901 align:start was provided by Desert Program Partners, 00:34.901 --> 00:37.570 align:start representing concerned viewers making a financial commitment 00:37.604 -->

provided by The Nature Conservancy. 00:50.784 --> 01:11.104 align:start ♪ music ♪ 01:18.912 --> 01:22.115 align:start The Amazon, the world's largest river system, 01:22.115 --> 01:27.287 align:start begins its journey high in the Andes of Peru. 01:27.287 --> 01:32.192 align:start More than 3,000 miles from its mouth, its main tributary 01:32.192 --> 01:35.662 align:start flows through wild and varied desert, 01:35.662 --> 01:38.598 align:start home to civilizations thousands of years before 01:38.598 --> 01:47.574 align:start the arrival of the Incas. 01:47.574 --> 01:50.243 align:start The geology of the Amazon desert is so convoluted, 01:50.243 --> 01:53.613 align:start twisted, faulted, that I need the help of my brother, 01:53.613 --> 01:57.450 align:start Dick Yetman, a geologist, to make sense of it all. 01:57.484 --> 02:00.120 align:start My Argentine friend, Axel Neilsen, will bring 02:00.120 --> 02:02.922 align:start an international cultural perspective 02:02.956 --> 02:07.861 align:start to the people we meet. 02:07.861 --> 02:11.731 align:start As we wind our way through the mountains east of Cajamarca, 02:11.731 --> 02:15.001 align:start we crown out at a pass over 10,000 feet. 02:15.001 --> 02:21.841 align:start Here we catch our first glimpse of the Amazon. 02:21.875 --> 02:25.979 align:start It lies 7,000 feet below us. 02:25.979 --> 02:30.150 align:start In Peru, it's called the Rio Marañón 02:30.150 --> 02:32.752 align:start and the canyon through which it flows is deeper 02:32.752 --> 02:37.957 align:start than the Grand Canyon. 02:44.164 --> 02:45.532 align:start Buenos dias! 02:45.532 --> 02:46.633 align:start A donde van. 02:46.633 --> 02:47.934 align:start Gracias. 02:47.934 --> 02:49.402 align:start A donde van. 02:49.402 --> 02:51.037 align:start Excellente. 02:51.037 --> 02:53.373 align:start Buena suerte. 02:53.373 --> 02:55.575 align:start How many dollars do you think they spend a year 02:55.575 --> 02:58.211 align:start maintaining this road? 02:58.211 --> 02:59.612 align:start 150. 02:59.646 --> 03:01.648 align:start So I suppose that helps. 03:01.648 --> 03:06.085 align:start It also makes it really a rough road. 03:06.085 --> 03:08.154 align:start The circulation of goods 03:08.154 --> 03:10.857 align:start between the eastern slopes of the Andes 03:10.857 --> 03:14.060 align:start and the Andean highlands and the coast, the maritime coast, 03:14.060 --> 03:16.229 align:start was very important throughout Andean history 03:16.229 --> 03:18.398 align:start and I could say that it is 03:18.398 --> 03:21.234 align:start even one of the hallmarks of Andean history 03:21.234 --> 03:25.638 align:start is this intensity of inter-regional trade. 03:25.672 --> 03:27.607 align:start I'd called this country vertical. 03:27.607 --> 03:30.777 align:start Oh, man, that's a long ways down and very slowly now 03:30.777 --> 03:33.880 align:start we will, you'll, we'll get out of the fog zone. 03:33.880 --> 03:37.083 align:start That valley's another 3,000 feet below us, possibly? 03:37.083 --> 03:41.054 align:start Well, it's possibly that much. 03:41.054 --> 03:43.089 align:start We know that at the beginning, 03:43.089 --> 03:45.458 align:start in the time of the hunter-gathers, 03:45.458 --> 03:49.095 align:start this is between 10,000 years ago and about 4,000 years ago, 03:49.095 --> 03:52.465 align:start some of these groups were combining their economies, 03:52.465 --> 03:55.501 align:start resources from the lowlands and from the highlands. 03:55.501 --> 03:58.871 align:start When the economy shifted to agricultural and pastoralism 03:58.871 --> 04:05.578 align:start and therefore these populations settled and became sedentary. 04:05.612 --> 04:12.919 align:start      (Spanish speaking woman) Si, hay blanca, roja,... 04:12.919 --> 04:16.923 align:start Y cada uno es diferente? 04:16.923 --> 04:19.959 align:start Es diferente. 04:19.993 --> 04:25.898 align:start So this is sufficient here for, almost for one family 04:25.898 --> 04:30.670 align:start for a year, they need a little more land, 04:30.670 --> 04:32.138 align:start but they don't sell these. 04:32.138 --> 04:34.507 align:start These are raised for the family. 04:34.507 --> 04:36.909 align:start They don't take the time to separate out the varieties. 04:36.909 --> 04:38.711 align:start They come out in various colors 04:38.745 --> 04:40.480 align:start and each color has its own flavor 04:40.480 --> 04:44.050 align:start and own place in the diet. 04:44.050 --> 04:46.786 align:start These fellas use the oxen in tandem, two pairs, 04:46.786 --> 04:49.222 align:start so that they can cover the field more quickly. 04:49.222 --> 04:51.557 align:start They're from the same family or clan 04:51.557 --> 04:53.559 align:start and working working together like this, 04:53.559 --> 04:56.562 align:start they can do a field in about a quarter of the time 04:56.562 --> 04:59.799 align:start as it would be if they were just to do it with one pair of oxen 04:59.799 --> 05:02.001 align:start at a time. 05:02.035 --> 05:03.803 align:start It is hard to settle in this very steep landscape 05:03.803 --> 05:06.172 align:start but this is an ideal place 05:06.172 --> 05:09.542 align:start for economically diversified economies 05:09.542 --> 05:13.313 align:start because you can access resources from very different environments 05:13.313 --> 05:16.783 align:start with a relatively short distance. 05:16.783 --> 05:18.785 align:start Archeologists have always paid too much attention 05:18.785 --> 05:21.888 align:start to the highlands and to the desert 05:21.888 --> 05:25.325 align:start mainly because the archeological sites are easier to find; 05:25.325 --> 05:28.461 align:start those environments and perishable materials, like 05:28.461 --> 05:31.664 align:start textiles and wood, preserve much better, so, what we find is, 05:31.698 --> 05:35.001 align:start archeology is much more impressive. 05:35.001 --> 05:37.904 align:start But we, we know that these eastern slopes of the Andes 05:37.904 --> 05:41.240 align:start and the forest played a major role 05:41.240 --> 05:44.010 align:start in all the history of the Andean highlands. 05:44.010 --> 05:46.012 align:start When we get to the Marañón, 05:46.012 --> 05:51.250 align:start its origin is about 500 miles south of us in, 05:51.250 --> 05:53.853 align:start still in Peru. 05:53.853 --> 05:55.221 align:start So it flows north? 05:55.221 --> 05:57.990 align:start So it's flowing north for 500 miles 05:57.990 --> 06:01.160 align:start and then another 100 after the bridge. 06:01.194 --> 06:04.397 align:start That is, my gosh, that's a long way down. 06:04.397 --> 06:08.167 align:start Look at the strike of that limestone down there. 06:08.201 --> 06:11.104 align:start If we focus on the last 4 or 5,000 years 06:11.104 --> 06:14.640 align:start we see a shift in the direction of influence 06:14.640 --> 06:17.176 align:start between highlands and lowlands 06:17.210 --> 06:19.312 align:start in the eastern side of the Andes. 06:19.312 --> 06:22.248 align:start At the beginning, the lowlands were much more important 06:22.248 --> 06:24.584 align:start because, through the lowlands, 06:24.584 --> 06:27.453 align:start some of the technologies, like ceramics, 06:27.487 --> 06:30.757 align:start and some of the important highland crops, like corn, 06:30.757 --> 06:33.793 align:start were introduced into the rest of the Andean area. 06:33.793 --> 06:37.263 align:start Later on, say a thousand years ago approximately, 06:37.263 --> 06:41.401 align:start we see a reversion in this trend. 06:41.401 --> 06:44.871 align:start Highland civilizations, which were more organized politically, 06:44.871 --> 06:47.540 align:start perhaps technologically more sophisticated, 06:47.540 --> 06:54.213 align:start began to exert an influence on the lowlands. 07:00.720 --> 07:03.856 align:start Just in case some skeptics should question 07:03.890 --> 07:07.126 align:start whether the Amazon really flows through desert or not, 07:07.160 --> 07:10.229 align:start I'd like to present a living proof. 07:10.263 --> 07:15.067 align:start This is the Sonoran Palo Verde, a native of the Sonoran Desert 07:15.067 --> 07:17.537 align:start and for many people, the proto-typical plant 07:17.537 --> 07:19.572 align:start of our great Sonoran Desert 07:19.572 --> 07:25.178 align:start here on the Rio Marañón in Peru. 07:25.178 --> 07:29.782 align:start As an example of evolution here in the Rio Marañón Valley, 07:29.816 --> 07:33.619 align:start this young browningia cactus, this species is found only here, 07:33.653 --> 07:37.924 align:start has these potent spines up to 3 inches long. 07:37.924 --> 07:40.893 align:start These are an effective deterrent against herbivores, 07:40.927 --> 07:45.565 align:start that is, mammals that would eat plants. 07:45.565 --> 07:47.266 align:start By the time the browningias have become adults, 07:47.300 --> 07:49.902 align:start generally about 20 year or so, 07:49.936 --> 07:53.473 align:start they have lost most of those spines so that their exterior 07:53.473 --> 07:56.576 align:start is just as smooth as can be, and I can stroke it 07:56.576 --> 07:59.979 align:start without any fear of being impaled. 07:59.979 --> 08:01.781 align:start They no longer need those spines because they're tough enough 08:01.781 --> 08:05.017 align:start to withstand the attacks of herbivores. 08:05.051 --> 08:11.057 align:start However not all columnar cacti lose their spines. 08:11.057 --> 08:13.826 align:start But this cactus, in addition to maintaining its spines, 08:13.860 --> 08:17.263 align:start develops this felt-y surface that's called a cephalium 08:17.263 --> 08:19.465 align:start and it has an interesting role 08:19.465 --> 08:22.401 align:start of protecting the developing flowers and fruits 08:22.401 --> 08:25.271 align:start so that predators can't get at them and eat them 08:25.271 --> 08:27.006 align:start before they're ripe. 08:27.006 --> 08:28.941 align:start When they ripen, they open up, 08:28.975 --> 08:31.644 align:start the pollinators have an easy way to get at them. 08:31.644 --> 08:33.279 align:start Until that time, 08:33.279 --> 08:38.384 align:start they're protected under that wooly cephalium. 08:42.088 --> 08:44.724 align:start It's surprising to find this bombax tree 08:44.724 --> 08:46.826 align:start growing here in the Amazon desert. 08:46.826 --> 08:49.228 align:start These get grotesquely big 08:49.262 --> 08:51.564 align:start and grow in all sorts of weird contortions. 08:51.564 --> 08:53.733 align:start They're a very tropical tree. 08:53.733 --> 08:55.434 align:start They don't grow in the Sonoran Desert 08:55.434 --> 08:58.137 align:start but right on the margins. 08:58.137 --> 09:00.940 align:start You can find a close relative of this tree growing, 09:00.940 --> 09:07.847 align:start so for my purposes, this is a good desert tree. 09:19.191 --> 09:25.464 align:start This little flower is a close relative of the poinsettia. 09:25.464 --> 09:29.201 align:start It's actually a member of the genus jatropha 09:29.201 --> 09:32.538 align:start and one characteristic of warm New World deserts 09:32.538 --> 09:40.279 align:start is an abundance of plants in this genus. 09:40.313 --> 09:44.817 align:start This cactus is a member of the genus armatocereus 09:44.817 --> 09:47.420 align:start but I call it the sausage cactus. 09:47.420 --> 09:49.689 align:start In addition to looking kind of strange, 09:49.689 --> 09:52.725 align:start it has a very unusual use. 09:52.725 --> 09:56.495 align:start Local people say that if you cut off a piece of an arm 09:56.495 --> 10:00.466 align:start and drop it into a bucket of muddy water 10:00.466 --> 10:04.503 align:start from the Rio Marañón, within two hours all the mud and impurities 10:04.503 --> 10:06.706 align:start will have dropped off into the bottom 10:06.706 --> 10:08.341 align:start and you can drink the water. 10:08.341 --> 10:15.247 align:start It's a natural water purifier. 10:15.247 --> 10:19.885 align:start Five hours later and 8,500 feet below where we first 10:19.885 --> 10:23.756 align:start spied the river, we reach its edge. 10:23.756 --> 10:26.592 align:start Across from us lies the sultry, buggy, 10:26.592 --> 10:33.666 align:start parasite-ridden village of Balsas. 10:33.666 --> 10:38.871 align:start Well, this is a river, this is a large river 10:38.871 --> 10:41.574 align:start and we're in a desert. 10:41.574 --> 10:44.510 align:start Why is it oxymoronic to have a river in the desert? 10:44.510 --> 10:46.479 align:start I don't know, it, it isn't, there's, all over the world, 10:46.479 --> 10:48.614 align:start the Nile is a river in the desert. 10:48.614 --> 10:50.716 align:start But there's something different here. 10:50.750 --> 10:53.152 align:start Now you tell me that this is granite, right, the basement? 10:53.152 --> 10:55.454 align:start This is the basement of the whole complex 10:55.488 --> 10:57.289 align:start which is really wonderful because we've been traveling 10:57.289 --> 10:58.624 align:start through limestone and sandstone for the last two days. 10:58.624 --> 10:59.925 align:start Yeah. 10:59.925 --> 11:02.395 align:start Thousands of feet of it and now 11:02.395 --> 11:05.564 align:start we get into the intrusive bottom which actually came underneath 11:05.564 --> 11:09.735 align:start and melted into the rock that was already there. 11:09.769 --> 11:11.904 align:start And those two huge ranges then, each of them 11:11.904 --> 11:14.840 align:start captures the rain, one coming from the Atlantic, 11:14.874 --> 11:17.076 align:start the other anything coming into the Pacific, 11:17.076 --> 11:19.311 align:start very little of it makes it down here. 11:19.311 --> 11:21.347 align:start So is, is that why it's in the desert? 11:21.347 --> 11:24.050 align:start Maybe when a place doesn't get much rain, 11:24.050 --> 11:28.487 align:start maybe that would be a desert. 11:28.521 --> 11:29.455 align:start Hey, look at the loading in that water. 11:29.455 --> 11:30.723 align:start My gosh. 11:30.723 --> 11:32.692 align:start Look at all the sediments. 11:32.692 --> 11:34.994 align:start You couldn't get a glass of this water 11:34.994 --> 11:36.696 align:start and I bet it would take a day for it to settle out completely. 11:36.696 --> 11:38.864 align:start Yeah, it's real, real fine stuff. 11:38.898 --> 11:40.599 align:start That is a lot of materials being transported. 11:40.599 --> 11:41.434 align:start And it's gotta come from somewhere. 11:41.434 --> 11:42.435 align:start Why? 11:42.435 --> 11:44.003 align:start Well, gravity. 11:44.003 --> 11:46.639 align:start That's, that's the way I was taught gravity works. 11:46.639 --> 11:48.574 align:start So all those, all the Andes are being worn down by rain 11:48.574 --> 11:50.576 align:start and they are being lifted up 11:50.576 --> 11:53.145 align:start by the plate tectonics you described. 11:53.179 --> 11:56.615 align:start It's weird but we are now about 500 miles north of the origin 11:56.615 --> 11:59.719 align:start of the Rio Marañón. 11:59.719 --> 12:02.655 align:start So what's collecting from all that basin, 12:02.655 --> 12:04.690 align:start bringing all that sediment here. 12:04.690 --> 12:07.693 align:start It's got 3500 miles to go to reach the Atlantic. 12:07.693 --> 12:09.228 align:start Cuantos años tiene el puente? 12:09.228 --> 12:13.299 align:start        (talking in Spanish) 12:13.299 --> 12:17.036 align:start Oh I thought thought this bridge only was 10 years old 12:17.036 --> 12:20.473 align:start and the bridge operator tells me it's actually forty years old. 12:20.473 --> 12:22.508 align:start So Balsas has not had Balsas operating 12:22.508 --> 12:25.945 align:start for the last 40 years. 12:25.945 --> 12:32.318 align:start Before that, everybody had to cross on rafts. 12:36.055 --> 12:38.157 align:start This great band of sandstone that we see up here, 12:38.157 --> 12:40.359 align:start which is probably a thousand foot thick, 12:40.359 --> 12:43.696 align:start as it gets off to the south, it suddenly just drops 12:43.696 --> 12:46.665 align:start straight off, almost vertical. 12:46.665 --> 12:49.268 align:start And this is one example of the great tectonic movement 12:49.268 --> 12:50.436 align:start that takes place here in the Andes, 12:50.436 --> 12:51.971 align:start the mountain building. 12:51.971 --> 12:54.974 align:start This is one of the examples of how it's done. 12:54.974 --> 12:57.777 align:start The forces that make this mountain building happen 12:57.777 --> 13:02.848 align:start are compression of sediments from one side to the other, 13:02.882 --> 13:06.585 align:start as well as forces within the earth 13:06.619 --> 13:09.822 align:start which are pushing up at the same time. 13:09.822 --> 13:11.624 align:start It's something that happens over such a long period of time, 13:11.624 --> 13:14.326 align:start but it does demonstrate the plasticity 13:14.360 --> 13:19.598 align:start that these rocks have. 13:19.632 --> 13:21.801 align:start Two years ago when I was traveling 13:21.801 --> 13:24.170 align:start in the Rio Marañón region, I noticed up on this hillside 13:24.170 --> 13:26.238 align:start a strange cactus. 13:26.272 --> 13:29.008 align:start I didn't know what it was, and later on, 13:29.008 --> 13:31.443 align:start I was able to identify it and subsequently found that 13:31.443 --> 13:34.747 align:start DNA studies have traced this to a very primitive 13:34.747 --> 13:37.817 align:start cactus that matter of fact, it is the grand-daddy, 13:37.817 --> 13:42.087 align:start the original cactus from which all of our columnar cacti 13:42.087 --> 13:48.627 align:start are evolved, including our beautiful saguaro cactus. 13:48.661 --> 13:51.363 align:start This fits in perfectly with the discovery 13:51.397 --> 13:59.405 align:start that the Rio Marañón is a hot spot of evolution of cacti. 13:59.405 --> 14:26.098 align:start Adelante, vamanos. Tell me if I'm wrong but it seems to me 14:26.098 --> 14:28.467 align:start the people in Chachapoyas are lighter skinned 14:28.467 --> 14:29.568 align:start and certainly look different from elsewhere in the Andes. 14:29.602 --> 14:31.604 align:start Yes. 14:31.604 --> 14:33.672 align:start Tradition has it that the women from Chachapoya were known 14:33.706 --> 14:35.941 align:start for their beauty and that the Incas took some of them 14:35.975 --> 14:38.244 align:start to serve as concubines for the kings 14:38.244 --> 14:40.846 align:start and some of them to serve as acllas, 14:40.846 --> 14:44.483 align:start this is virgins of the sun, the chosen ones, 14:44.483 --> 14:47.519 align:start for sacrifices and, you know for weaving the special clothes 14:47.519 --> 14:51.257 align:start for the Inca and other special chores like that. 14:51.257 --> 14:53.659 align:start I've heard that the Spaniards reported 14:53.659 --> 14:56.128 align:start that Chachapoyans had light colored eyes 14:56.128 --> 14:58.464 align:start in addition to skin? 14:58.464 --> 15:02.134 align:start Yeah, that's, that's a mystery and light hair 15:02.134 --> 15:06.438 align:start and that sort of gave way to all sorts of speculations 15:06.472 --> 15:10.276 align:start about you know, transatlantic contact before Columbus. 15:10.276 --> 15:12.845 align:start Chachapoyas has a different flavor to it, 15:12.845 --> 15:15.414 align:start a different feeling than other places that we've been, 15:15.414 --> 15:18.150 align:start southern, central and northern Peru. 15:18.150 --> 15:19.318 align:start Yes, and very different from the people of the highlands. 15:19.318 --> 15:21.053 align:start Yeah. 15:21.053 --> 15:23.689 align:start Although, look, we're over 8000 feet here 15:23.689 --> 15:26.892 align:start so it's not at sea level by any means. 15:26.892 --> 15:29.328 align:start I see all this forest and I think we're the lowlands 15:29.328 --> 15:33.365 align:start you know but you're right, actually we're quite high. 15:33.399 --> 15:35.534 align:start Look, almost every building around the plaza 15:35.534 --> 15:38.671 align:start is a travel agency or a cyber café. 15:38.671 --> 15:40.839 align:start Yeah, big time attraction for tourists. 15:40.839 --> 15:41.774 align:start They know the two things that tourists need, 15:41.774 --> 15:44.376 align:start tours and internet. 15:44.410 --> 15:46.045 align:start Write home. 15:46.045 --> 15:47.179 align:start Write home, that's right. 15:47.179 --> 15:49.515 align:start Hey, we're in Chachapoyas. 15:49.515 --> 15:51.684 align:start But the reality is that Chachapoyas is the only 15:51.684 --> 15:55.120 align:start colonial town in the cloud forest and I have to 15:55.154 --> 15:58.023 align:start break the news to you that we're going to go back down 15:58.057 --> 15:59.525 align:start to places where there are more cacti. 15:59.525 --> 16:01.994 align:start Oh, okay. 16:01.994 --> 16:04.029 align:start Now I know you should rejoice at that, but I, 16:04.063 --> 16:05.431 align:start I'd like to see you a little bit happier. 16:05.431 --> 16:06.865 align:start Hey, I'll follow you. 16:06.865 --> 16:12.071 align:start Okay. 16:12.071 --> 16:15.674 align:start The water that enters the Amazon is a massive 16:15.708 --> 16:18.677 align:start amount of water from a very complex system. 16:18.711 --> 16:22.114 align:start The Andes have so much limestone in them 16:22.114 --> 16:24.583 align:start that they create such a tremendous aquifer 16:24.583 --> 16:28.087 align:start which holds so much water and to release that water 16:28.087 --> 16:33.859 align:start gradually into these rivers which drain this vast system. 16:36.362 --> 16:40.099 align:start These north-south trending canyons seem to have 16:40.099 --> 16:45.170 align:start formed along faults between these blocks of mountains. 16:45.204 --> 16:48.640 align:start So the mountains dip apart like this and then they 16:48.640 --> 16:51.744 align:start can go up or down depending on the forces 16:51.744 --> 16:54.179 align:start but it creates a weak zone and the rivers seem to be 16:54.213 --> 16:57.583 align:start carving themselves along those zones. 17:00.319 --> 17:02.988 align:start When we see water released, 17:02.988 --> 17:07.226 align:start virtually into the air as this one is, it means that there is 17:07.226 --> 17:11.463 align:start a great amount of hydrostatic pressure on that water 17:11.497 --> 17:19.138 align:start from a great elevation, from a great distance. 17:19.138 --> 17:21.707 align:start 2,000 miles downstream we're goin' to be 17:21.707 --> 17:24.076 align:start out of the mountains, like we are now. 17:24.076 --> 17:26.512 align:start We're out of the Sierra, we're in the foothills 17:26.512 --> 17:29.481 align:start and there will be a lot more vegetation so the water 17:29.515 --> 17:32.751 align:start will be flatter but maybe broader, and of course 17:32.785 --> 17:35.020 align:start the volume will have increased tenfold 17:35.020 --> 17:38.991 align:start by the time we reach that point. 17:40.893 --> 17:42.561 align:start Let's cross the Urubamba. 17:42.561 --> 17:45.197 align:start As it's now, it's the dirty Urubamba. 17:45.197 --> 17:46.865 align:start Yeah, it was clear. 17:46.899 --> 17:48.567 align:start Buenos dias, señora. 17:48.567 --> 17:50.569 align:start        (talking in Spanish) 17:50.569 --> 17:57.443 align:start So this cart is the main, 17:57.443 --> 18:06.151 align:start the transportation for the entire village here. 18:06.185 --> 18:08.387 align:start This is looking like a sediment river now. 18:08.387 --> 18:10.122 align:start Yeah, yeah. 18:10.122 --> 18:11.757 align:start So the bottom would be sandy here, right?
