1 00:00:02,000 --> 00:00:07,721 On the morning of June thirtieth, 1956, two airliners took off from Los Angeles 2 00:00:07,771 --> 00:00:09,182 three minutes apart. 3 00:00:09,232 --> 00:00:13,857 The first was a TWA Super Constellation, headed for Kansas City. 4 00:00:13,907 --> 00:00:17,436 The second was a United DC-7, headed for Chicago. 5 00:00:17,486 --> 00:00:21,600 Between them, they carried a hundred twenty-eight people. 6 00:00:21,650 --> 00:00:24,741 Their routes crossed over northern Arizona. 7 00:00:24,791 --> 00:00:30,877 And back then, once a plane left the area around a big airport, nobody on the ground 8 00:00:30,927 --> 00:00:32,703 was watching it on radar. 9 00:00:32,753 --> 00:00:37,378 Out over open country, pilots kept each other apart the old way. 10 00:00:37,428 --> 00:00:39,351 They looked out the window. 11 00:00:39,401 --> 00:00:40,519 See and be seen. 12 00:00:41,369 --> 00:00:45,715 That morning, there were tall clouds building over the Grand Canyon. 13 00:00:45,765 --> 00:00:50,110 Both planes ended up at the same altitude, twenty-one thousand feet. 14 00:00:50,160 --> 00:00:53,665 At about half past ten, they collided above the canyon. 15 00:00:53,715 --> 00:00:54,700 Nobody survived. 16 00:00:54,750 --> 00:00:59,354 The investigators later listed a few things that may have played a part. 17 00:00:59,404 --> 00:01:00,065 The clouds. 18 00:01:00,115 --> 00:01:00,453 Winds. 19 00:01:00,503 --> 00:01:03,491 And one more possibility that's hard to forget. 20 00:01:03,541 --> 00:01:08,403 The crews may have been giving their passengers a better look at the canyon. 21 00:01:08,453 --> 00:01:09,955 Nobody can say for sure. 22 00:01:10,805 --> 00:01:14,269 What happened next is the part most people never hear. 23 00:01:14,319 --> 00:01:16,157 That crash shook the country. 24 00:01:16,207 --> 00:01:21,624 Within two years, Congress passed the Federal Aviation Act, and a new federal agency 25 00:01:21,674 --> 00:01:24,553 took over the job of keeping airplanes apart. 26 00:01:24,603 --> 00:01:26,180 Today we call it the FAA. 27 00:01:26,230 --> 00:01:31,647 The radar coverage, the controlled airspace, the whole system that watches over your 28 00:01:31,697 --> 00:01:35,227 flight, grew out of that morning over the Grand Canyon. 29 00:01:35,277 --> 00:01:40,564 So if you've flown anywhere, you've been protected by a lesson this canyon taught. 30 00:01:45,614 --> 00:01:47,816 Welcome back to Talk Travel with Glen. 31 00:01:47,866 --> 00:01:52,793 I'm Glen, and this is Season Three, where we're traveling through America's national 32 00:01:52,843 --> 00:01:56,823 parks one park at a time, looking for the stories under the scenery. 33 00:01:56,873 --> 00:02:00,438 Last time, we were in Yellowstone, where the ground is alive. 34 00:02:00,488 --> 00:02:05,060 This time, we're standing at the edge of the most famous hole in the ground on 35 00:02:05,110 --> 00:02:05,415 Earth. 36 00:02:05,465 --> 00:02:06,423 The Grand Canyon. 37 00:02:12,473 --> 00:02:16,426 Start with the size of it, because nothing prepares you for that. 38 00:02:16,476 --> 00:02:19,444 The Grand Canyon is about a mile deep on average. 39 00:02:19,494 --> 00:02:24,557 From one rim to the other, it averages ten miles across, and in places it stretches 40 00:02:24,607 --> 00:02:25,296 to eighteen. 41 00:02:25,346 --> 00:02:29,854 The South Rim, where most people stand, sits at about seven thousand feet. 42 00:02:29,904 --> 00:02:33,734 The North Rim, across the gap, is about a thousand feet higher. 43 00:02:33,784 --> 00:02:36,075 But the depth is not really the story. 44 00:02:36,125 --> 00:02:37,676 The story is in the walls. 45 00:02:38,526 --> 00:02:44,546 Those stripes of red and tan and cream are layers of rock, stacked one on top of 46 00:02:44,596 --> 00:02:47,732 another, and each layer is a page of time. 47 00:02:47,782 --> 00:02:52,588 The top layer, right at the rim, is called the Kaibab Formation. 48 00:02:52,638 --> 00:02:56,305 It's about two hundred seventy million years old. 49 00:02:56,355 --> 00:03:02,374 Keep going down, layer after layer, and you're going back in time the whole way. 50 00:03:03,224 --> 00:03:08,218 At the very bottom, down in the dark inner gorge, the oldest rocks are about one 51 00:03:08,268 --> 00:03:10,109 point eight billion years old. 52 00:03:10,159 --> 00:03:14,964 That's well over a third of the age of the Earth, all stacked up in one view. 53 00:03:15,014 --> 00:03:18,179 Now here's the thing most visitors walk right past. 54 00:03:18,229 --> 00:03:21,268 Somewhere in those walls, there's a page missing. 55 00:03:21,318 --> 00:03:22,908 Actually, a whole chapter. 56 00:03:23,758 --> 00:03:29,441 Down near the bottom, there's a line where flat, layered sandstone sits right on top 57 00:03:29,491 --> 00:03:31,966 of that ancient, twisted bottom rock. 58 00:03:32,016 --> 00:03:36,471 Rock from one age, sitting directly on rock from a much older one. 59 00:03:36,521 --> 00:03:39,815 Geologists call that kind of gap an unconformity. 60 00:03:39,865 --> 00:03:45,480 John Wesley Powell, the first man to lead an expedition through the canyon by boat, 61 00:03:45,530 --> 00:03:47,049 gave this one its name. 62 00:03:47,099 --> 00:03:48,619 The Great Unconformity. 63 00:03:48,669 --> 00:03:51,213 How much time is missing at that line? 64 00:03:51,263 --> 00:03:53,533 About one point two billion years. 65 00:03:54,383 --> 00:03:55,206 Think about that. 66 00:03:55,256 --> 00:03:59,159 More than a billion years of Earth's history happened here, and the rock that 67 00:03:59,209 --> 00:04:02,701 recorded it was worn away before the next layer was laid down on top. 68 00:04:02,751 --> 00:04:05,165 The canyon shows you an enormous amount of time. 69 00:04:05,215 --> 00:04:07,321 It also shows you where time went missing. 70 00:04:08,171 --> 00:04:11,476 If you want to see it with your own eyes, you can. 71 00:04:11,526 --> 00:04:16,778 The park says it's visible from several spots on the South Rim, including Lipan 72 00:04:16,828 --> 00:04:20,335 Point and the area around the Yavapai Geology Museum. 73 00:04:20,385 --> 00:04:25,838 You're looking for the place where the neat, flat layers stop and the dark, tilted 74 00:04:25,888 --> 00:04:26,643 rock begins. 75 00:04:27,493 --> 00:04:32,984 And while you're looking out there, you'll notice the big peaks inside the canyon 76 00:04:33,034 --> 00:04:34,625 have some unusual names. 77 00:04:34,675 --> 00:04:35,788 Zoroaster Temple. 78 00:04:35,838 --> 00:04:36,746 Brahma Temple. 79 00:04:36,796 --> 00:04:37,567 Deva Temple. 80 00:04:37,617 --> 00:04:42,971 In the 1870s, a geologist and mapmaker named Clarence Dutton started naming the 81 00:04:43,021 --> 00:04:48,648 canyon's great formations after temples and figures from the world's old religions. 82 00:04:48,698 --> 00:04:53,026 To him, they looked like ancient pagodas rising out of the rock. 83 00:04:53,076 --> 00:04:56,857 Once you hear that, it's hard to see them any other way. 84 00:05:01,907 --> 00:05:02,907 Here's a twist. 85 00:05:02,957 --> 00:05:04,307 The rock is ancient. 86 00:05:04,357 --> 00:05:05,567 The canyon is not. 87 00:05:05,617 --> 00:05:11,096 The Colorado River has been carving the Grand Canyon for only about five to six 88 00:05:11,146 --> 00:05:12,076 million years. 89 00:05:12,126 --> 00:05:15,016 In the life of a landscape, that's recent. 90 00:05:15,066 --> 00:05:17,396 The rock is billions of years old. 91 00:05:17,446 --> 00:05:19,706 The hole cut through it is young. 92 00:05:19,756 --> 00:05:22,226 So how does a river cut a mile down? 93 00:05:23,076 --> 00:05:24,356 It happened in steps. 94 00:05:24,406 --> 00:05:28,853 First, over hundreds of millions of years, those layers were laid down. 95 00:05:28,903 --> 00:05:32,274 Sand, mud, shells, the floors of old seas and deserts. 96 00:05:32,324 --> 00:05:37,278 Then, sometime around seventy to thirty million years ago, the whole region was 97 00:05:37,328 --> 00:05:42,219 pushed upward, thousands of feet, into what's now called the Colorado Plateau. 98 00:05:43,069 --> 00:05:44,560 That set everything up. 99 00:05:44,610 --> 00:05:49,582 With the land lifted that high, the river had a long, steep run to the sea. 100 00:05:49,632 --> 00:05:55,073 Steep water moves fast, fast water carries rock and sand, and rock and sand scour. 101 00:05:55,123 --> 00:05:58,823 So the river started cutting down, and it never stopped. 102 00:05:58,873 --> 00:06:03,711 Meanwhile, side streams, rain, ice and gravity went to work on the walls. 103 00:06:03,761 --> 00:06:05,921 That's why the canyon is so wide. 104 00:06:05,971 --> 00:06:10,340 Today it's actually getting wider faster than it's getting deeper. 105 00:06:11,190 --> 00:06:16,629 The river itself runs about two hundred seventy-seven miles through the canyon, and 106 00:06:16,679 --> 00:06:19,737 it drops about two thousand feet along the way. 107 00:06:19,787 --> 00:06:24,564 The channel averages about three hundred feet across and forty feet deep. 108 00:06:24,614 --> 00:06:28,003 And before there were dams, that river had a temper. 109 00:06:28,053 --> 00:06:32,896 Spring floods could top a hundred thousand cubic feet of water per second. 110 00:06:32,946 --> 00:06:37,591 The biggest flood on record, in 1884, ran about three hundred thousand. 111 00:06:37,641 --> 00:06:43,146 Today, with the dam upstream, the river usually runs anywhere from twelve to fifteen 112 00:06:43,196 --> 00:06:43,741 thousand. 113 00:06:44,591 --> 00:06:47,349 But people were not the first to dam this river. 114 00:06:47,399 --> 00:06:48,987 The canyon did it to itself. 115 00:06:49,037 --> 00:06:53,842 Starting about six hundred thirty thousand years ago, volcanoes on the western side 116 00:06:53,892 --> 00:06:57,586 of the canyon sent lava pouring over the rim and into the river. 117 00:06:57,636 --> 00:06:59,691 It happened at least thirteen times. 118 00:06:59,741 --> 00:07:04,371 The lava cooled and blocked the river completely, and lakes backed up behind it. 119 00:07:04,421 --> 00:07:07,998 One of those lava dams stood more than two thousand feet high. 120 00:07:08,048 --> 00:07:12,209 That's taller than Glen Canyon Dam, the big concrete one upstream today. 121 00:07:13,060 --> 00:07:15,495 Every one of those lava dams is gone now. 122 00:07:15,545 --> 00:07:17,557 The river worked through them all. 123 00:07:17,607 --> 00:07:21,619 Which tells you everything about who wins in the long run out here. 124 00:07:26,669 --> 00:07:30,659 So who was the first to follow that river all the way through? 125 00:07:30,709 --> 00:07:36,002 On May twenty-fourth, 1869, a one-armed Civil War veteran named John Wesley Powell 126 00:07:36,052 --> 00:07:39,781 pushed off from Green River Station, in Wyoming Territory. 127 00:07:39,831 --> 00:07:42,909 He'd lost his right arm at the Battle of Shiloh. 128 00:07:42,959 --> 00:07:48,252 Now he had nine men with him, four wooden boats, and a plan to run the Green River 129 00:07:48,302 --> 00:07:53,073 down to the Colorado, and the Colorado through a canyon nobody had mapped. 130 00:07:53,923 --> 00:07:55,287 It went wrong early. 131 00:07:55,337 --> 00:08:01,082 In June, one of the boats, the No Name, hit a stretch of rapids and was smashed to 132 00:08:01,132 --> 00:08:01,577 pieces. 133 00:08:01,627 --> 00:08:07,372 The men aboard washed up on shore alive, but a good part of the supplies went with 134 00:08:07,422 --> 00:08:08,008 the boat. 135 00:08:08,058 --> 00:08:10,835 The spot is still called Disaster Falls. 136 00:08:11,685 --> 00:08:12,545 They kept going. 137 00:08:12,595 --> 00:08:17,152 On August tenth, they reached the place where the Little Colorado River flows in. 138 00:08:17,202 --> 00:08:19,598 That's the edge of the Grand Canyon proper. 139 00:08:19,648 --> 00:08:23,977 And a few days later, with their food running low and their boats patched and 140 00:08:24,027 --> 00:08:28,243 leaking, Powell wrote one of the most famous lines in American exploration. 141 00:08:28,293 --> 00:08:31,770 "We are now ready to start on our way down the Great Unknown." 142 00:08:32,620 --> 00:08:37,716 For the next two weeks, they ran rapids, carried boats around the ones they couldn't 143 00:08:37,766 --> 00:08:41,209 run, and watched the walls climb higher over their heads. 144 00:08:41,259 --> 00:08:46,355 They were wet, they were hungry, and they had no idea what was around the next bend. 145 00:08:46,405 --> 00:08:51,441 Then, on August twenty-eighth, they came to a rapid that looked worse than anything 146 00:08:51,491 --> 00:08:51,686 yet. 147 00:08:51,736 --> 00:08:53,892 And three of the men had had enough. 148 00:08:53,942 --> 00:08:58,793 Two brothers, Oramel and Seneca Howland, and a man named William Dunn decided to 149 00:08:58,843 --> 00:09:02,960 climb out of the canyon and walk to a settlement rather than run it. 150 00:09:03,810 --> 00:09:05,603 The group split up right there. 151 00:09:05,653 --> 00:09:07,150 The three men climbed out. 152 00:09:07,200 --> 00:09:08,340 The rest pushed off. 153 00:09:08,390 --> 00:09:09,886 The boats made it through. 154 00:09:09,936 --> 00:09:14,704 Two days later, Powell and the men still with him reached the mouth of the Virgin 155 00:09:14,754 --> 00:09:15,716 River and safety. 156 00:09:15,766 --> 00:09:16,608 They'd done it. 157 00:09:17,458 --> 00:09:20,373 The three men who walked out were never seen again. 158 00:09:20,423 --> 00:09:25,141 Powell later reported that they'd been killed by men from the Shivwits band of the 159 00:09:25,191 --> 00:09:25,548 Paiute. 160 00:09:25,598 --> 00:09:30,315 That account has been questioned by historians ever since, and to this day, nobody 161 00:09:30,365 --> 00:09:32,641 knows for certain what happened to them. 162 00:09:32,691 --> 00:09:37,059 The side canyon where they left the river is still called Separation Canyon. 163 00:09:37,109 --> 00:09:38,804 Powell went on to run the U.S. 164 00:09:38,854 --> 00:09:39,850 Geological Survey. 165 00:09:39,900 --> 00:09:44,734 But he's remembered for that summer, and for the line that still gives people chills 166 00:09:44,784 --> 00:09:45,781 when they read it. 167 00:09:45,831 --> 00:09:46,827 The Great Unknown. 168 00:09:51,877 --> 00:09:54,386 Now, "unknown" depends on who you ask. 169 00:09:54,436 --> 00:09:56,676 Powell's crew were strangers here. 170 00:09:56,726 --> 00:09:58,427 Plenty of people were not. 171 00:09:58,477 --> 00:10:03,478 Down on the river, there's a stretch of flat ground called the Unkar Delta. 172 00:10:03,528 --> 00:10:09,068 About a thousand years ago, mostly in the years from 1050 to 1150, people lived and 173 00:10:09,118 --> 00:10:11,762 farmed right there, beside the Colorado. 174 00:10:11,812 --> 00:10:16,679 Archaeologists have identified fifty-two sites on that one stretch alone. 175 00:10:17,529 --> 00:10:23,026 High up on the cliffs above the river at a place called Nankoweap, you can still see 176 00:10:23,076 --> 00:10:25,865 small stone rooms tucked under an overhang. 177 00:10:25,915 --> 00:10:27,054 They're granaries. 178 00:10:27,104 --> 00:10:27,912 Food storage. 179 00:10:27,962 --> 00:10:32,535 Built way up the wall, they kept grain safe from rodents and from rot. 180 00:10:32,585 --> 00:10:37,817 Somebody climbed up there with their harvest, a long time ago, and made it work. 181 00:10:37,867 --> 00:10:42,770 All told, the park has more than three thousand documented ancestral sites. 182 00:10:42,820 --> 00:10:47,591 And eleven tribes still have deep, traditional ties to this canyon today. 183 00:10:48,441 --> 00:10:52,803 For the Hopi, one of those ties runs through the Little Colorado River. 184 00:10:52,853 --> 00:10:55,413 Its water can be an unreal turquoise blue. 185 00:10:55,463 --> 00:11:00,634 That color comes from dissolved minerals, mostly calcium carbonate, which also coats 186 00:11:00,684 --> 00:11:02,374 the riverbed in white stone. 187 00:11:02,424 --> 00:11:07,346 The Hopi tie that river to their story of emergence, the place their people came 188 00:11:07,396 --> 00:11:08,340 into this world. 189 00:11:08,390 --> 00:11:11,075 And here's one most people never hear about. 190 00:11:11,125 --> 00:11:13,996 Some people still live inside the Grand Canyon. 191 00:11:14,846 --> 00:11:20,638 The Havasupai village of Supai sits deep in a side canyon, outside the national 192 00:11:20,688 --> 00:11:22,413 park, on Havasupai land. 193 00:11:22,463 --> 00:11:23,818 There's no road in. 194 00:11:23,868 --> 00:11:27,219 So how do you get mail to a town with no road? 195 00:11:27,269 --> 00:11:27,811 By mule. 196 00:11:27,861 --> 00:11:34,023 Mail for Supai goes down the trail on the backs of mules, six days a week, each mule 197 00:11:34,073 --> 00:11:36,537 carrying up to two hundred pounds. 198 00:11:36,587 --> 00:11:41,713 It takes about three hours to get down and about five to come back up. 199 00:11:41,763 --> 00:11:47,925 The National Postal Museum has called it the last official mail-by-mule route in the 200 00:11:47,975 --> 00:11:48,517 country. 201 00:11:49,367 --> 00:11:53,794 So the next time somebody tells you the mail always gets through, you can tell them 202 00:11:53,844 --> 00:11:54,442 about Supai. 203 00:11:59,491 --> 00:12:02,060 One last story before we get practical. 204 00:12:02,110 --> 00:12:07,631 Stand on the rim long enough and you might see a huge dark bird riding the warm air 205 00:12:07,681 --> 00:12:09,309 rising out of the canyon. 206 00:12:09,359 --> 00:12:14,478 If its wings look like they go on forever, you may be looking at a California 207 00:12:14,528 --> 00:12:14,948 condor. 208 00:12:14,998 --> 00:12:18,708 Their wings can reach about nine and a half feet across. 209 00:12:18,758 --> 00:12:21,661 It's the largest land bird in North America. 210 00:12:21,711 --> 00:12:24,279 In the 1980s, condors were almost gone. 211 00:12:24,329 --> 00:12:26,025 Only twenty-two were left. 212 00:12:26,075 --> 00:12:31,126 Every last wild one was eventually captured, so the species could be bred in 213 00:12:31,176 --> 00:12:32,469 captivity and saved. 214 00:12:33,319 --> 00:12:38,811 Then, on December twelfth, 1996, the first condors were set free again in northern 215 00:12:38,861 --> 00:12:42,731 Arizona, at the Vermilion Cliffs, not far from the canyon. 216 00:12:42,781 --> 00:12:48,340 As of the summer of 2025, there were eighty-two flying free in the Arizona and Utah 217 00:12:48,390 --> 00:12:48,746 flock. 218 00:12:48,796 --> 00:12:54,287 Worldwide, there are now more than five hundred sixty condors, and more than three 219 00:12:54,337 --> 00:12:56,923 hundred sixty of them live in the wild. 220 00:12:57,773 --> 00:13:00,409 The biggest threat they face today is lead. 221 00:13:00,459 --> 00:13:05,344 Condors eat dead animals, and when an animal was shot with lead ammunition, the 222 00:13:05,394 --> 00:13:08,030 fragments can poison the bird that eats it. 223 00:13:08,080 --> 00:13:12,216 A lot of hunters in the region now use non-lead ammunition to help. 224 00:13:12,266 --> 00:13:14,340 From twenty-two birds to hundreds. 225 00:13:14,390 --> 00:13:19,087 It's not finished, but it's one of the great comebacks in American wildlife. 226 00:13:23,137 --> 00:13:23,407 Okay. 227 00:13:23,457 --> 00:13:27,696 If this has you thinking about a trip, here's what's worth knowing. 228 00:13:28,545 --> 00:13:29,852 First, pick your rim. 229 00:13:29,902 --> 00:13:34,567 The South Rim is the one most people mean when they say the Grand Canyon. 230 00:13:34,617 --> 00:13:39,798 It's open all year, and it has the classic viewpoints, the lodges and the shuttle 231 00:13:39,848 --> 00:13:40,186 buses. 232 00:13:40,236 --> 00:13:45,353 The North Rim is quieter, higher and cooler, and it's a long drive around to get 233 00:13:45,403 --> 00:13:45,741 there. 234 00:13:45,791 --> 00:13:50,972 One big change to know about: in July of 2025, a wildfire called the Dragon Bravo 235 00:13:51,022 --> 00:13:55,106 Fire destroyed the historic Grand Canyon Lodge on the North Rim. 236 00:13:55,156 --> 00:14:00,337 The North Rim has reopened to visitors, but for now there's no lodging inside the 237 00:14:00,387 --> 00:14:03,567 park on that side, so you'd stay outside the park. 238 00:14:03,617 --> 00:14:05,246 It also closes for winter. 239 00:14:05,296 --> 00:14:10,478 This year, the park says it's open through November thirtieth, or until the first 240 00:14:10,528 --> 00:14:11,382 big snowstorm. 241 00:14:11,432 --> 00:14:16,097 Check the park's North Rim status page before you go, because it changes. 242 00:14:16,947 --> 00:14:18,390 Second, respect the hike. 243 00:14:18,440 --> 00:14:23,347 The trails down are steep, and the park's warning is blunt: do not try to hike from 244 00:14:23,397 --> 00:14:25,795 the rim to the river and back in one day. 245 00:14:25,845 --> 00:14:30,692 That's especially true from May through September, when the heat at the bottom can 246 00:14:30,742 --> 00:14:31,886 turn dangerous fast. 247 00:14:31,936 --> 00:14:35,290 Some trails, like the South Kaibab, have no water at all. 248 00:14:35,340 --> 00:14:38,455 The park does more than three hundred rescues a year. 249 00:14:38,505 --> 00:14:39,769 Going down feels easy. 250 00:14:39,819 --> 00:14:41,382 Coming back up is the hike. 251 00:14:42,232 --> 00:14:44,327 Third, go see the missing time. 252 00:14:44,377 --> 00:14:49,657 Stop at Lipan Point or the Yavapai Geology Museum area and look for the Great 253 00:14:49,707 --> 00:14:50,557 Unconformity. 254 00:14:50,607 --> 00:14:55,055 Once you've spotted it, you'll never see the canyon the same way. 255 00:14:55,105 --> 00:14:56,578 Fourth, watch the sky. 256 00:14:56,628 --> 00:15:01,146 Bring binoculars and look for condors riding the air near the rim. 257 00:15:01,196 --> 00:15:06,545 Many of them carry big numbered tags on their wings, so you can sometimes tell 258 00:15:06,595 --> 00:15:09,106 exactly which bird you're looking at. 259 00:15:09,956 --> 00:15:11,384 And last, book early. 260 00:15:11,434 --> 00:15:15,115 Lodging on the South Rim fills up well ahead of time. 261 00:15:15,165 --> 00:15:20,816 I'll put links to places to stay and tours worth your time on the episode page at 262 00:15:20,866 --> 00:15:26,025 travelwithglen.com, along with every source for the facts in this episode. 263 00:15:27,575 --> 00:15:29,937 So think back to where we started. 264 00:15:29,987 --> 00:15:35,682 Two airplanes over the canyon on a summer morning in 1956, and maybe, just maybe, 265 00:15:35,732 --> 00:15:39,583 two flight crews who wanted their passengers to see it. 266 00:15:39,633 --> 00:15:41,356 I understand the feeling. 267 00:15:41,406 --> 00:15:43,768 That's what the Grand Canyon does. 268 00:15:43,818 --> 00:15:45,825 It makes people want to look. 269 00:15:45,875 --> 00:15:51,286 A mile of rock, close to two billion years of time in the walls, a chapter of 270 00:15:51,336 --> 00:15:56,748 history missing right in the middle, and a river still at work at the bottom. 271 00:15:57,598 --> 00:16:03,772 If you'd like to see it, the full episode with footage from the park is on the 272 00:16:03,822 --> 00:16:06,405 Travel With Glen channel on Roku. 273 00:16:06,455 --> 00:16:11,752 Search for Travel With Glen, or add it with the code T Q G K V J X. 274 00:16:11,802 --> 00:16:13,268 It's free to watch. 275 00:16:13,318 --> 00:16:19,891 And if this episode was worth your time, follow the show wherever you're listening, 276 00:16:19,941 --> 00:16:22,764 so Season Three keeps coming to you. 277 00:16:22,814 --> 00:16:25,557 Next time, we're going to Yosemite. 278 00:16:25,607 --> 00:16:26,275 I'm Glen. 279 00:16:26,325 --> 00:16:28,589 Thanks for traveling with me.
