New Footage Beneath Lake Powell Reveals What Emerged After 60 Years Underwater

[00:00:00]60 years ago, a great dam sealed off a river in the American Southwest, and the rising water swallowed one of the most beautiful landscapes on Earth.

[00:00:10]A hidden world of red rock canyons, secret waterfalls, and a natural stone cathedral so magnificent that people wept when they saw it. All vanishing beneath hundreds of feet of water, seemingly forever.

[00:00:25]For decades, it was gone, drowned, and forgotten.

[00:00:30]But recently, as the largest drought in 1200 years drained that reservoir to its lowest level in history, the water began to pull back.

[00:00:40]And cameras captured something almost no living person ever expected to see again.

[00:00:46]A lost world emerging from the depths, coming back to life before our eyes.

[00:00:53]the canyon that was sacrificed. To understand what has emerged, you first have to understand what was lost.

[00:01:01]And to do that, we have to go back to a place that most people today have never even heard of because it spent the last 60 years hidden beneath the water.

[00:01:10]Its name was Glen Canyon.

[00:01:13]Glen Canyon was a vast and spectacular stretch of the Colorado River, winding through the deserts of what is now southern Utah and northern Arizona.

[00:01:23]And by many accounts of those lucky enough to see it before it vanished, it was one of the most beautiful places in all of North America.

[00:01:32]Arrival, some said, to the Grand Canyon itself, though utterly different in character.

[00:01:39]Where the Grand Canyon overwhelms you with its sheer scale and grandeur, Glen Canyon enchanted people with its intimacy and its secrets.

[00:01:49]It was a labyrinth of glowing red sandstone carved by water over countless ages into a maze of narrow side canyons, hidden aloves, natural arches, quiet grotto, and tucked away waterfalls.

[00:02:03]It was called Glenn Canyon precisely because of these features. a glenn being a secluded verdant valley. And these glenns were exactly that, green living oases tucked into the rock, where hanging gardens of ferns and wild flowers clung to seeping sandstone walls, where clear streams pulled in shaded chambers, where the desert unexpectedly gave way to lush, secret pockets of life.

[00:02:32]It was a place of profound quiet and beauty, layered with thousands of years of human history, dotted with the traces of the ancestral peoples who had lived among its canyons long before.

[00:02:44]But in the middle of the 20th century, the growing American Southwest was desperate for water and power. Engineers looked at the Colorado River and saw not a wonder to be preserved, but a resource to be harnessed.

[00:02:58]And so a decision was made that would erase Glen Canyon from the living world.

[00:03:03]They would build a dam.

[00:03:05]Construction on the Glen Canyon Dam was carried out through the late 1950s and into the early 1960s, and the Great Concrete Wall was completed in 1963.

[00:03:17]It rises more than 700 ft high. An immense plug of concrete thrown across the Colorado River near the town of Paige, Arizona.

[00:03:27]Its purpose was to trap the river's water, to store it against times of drought, and to generate hydroelectric power for millions of people across the region.

[00:03:37]And the moment that dam was finished and its gates were closed, the river had nowhere to go. The water began to back up behind the concrete. It began to rise. and Glenn Canyon, the secret Glenns, the hanging gardens, the hidden waterfalls, the ancient sites, all of it began slowly and inexurably to drown.

[00:04:01]The rising water, the flooding of Glen Canyon was not a sudden event. It was a slow, creeping tragedy that unfolded over the course of many years as the trapped water climbed higher and higher up the canyon walls.

[00:04:16]When the gates of the Glen Canyon Dam closed, the Colorado River began filling the canyon behind it, creating an enormous artificial reservoir.

[00:04:26]That reservoir was named Lake Powell, after John Wesley Powell, the one-armed Civil War veteran and explorer who had famously led the first expedition down this stretch of the Colorado in 1869. It would grow to become the second largest artificial reservoir in the entire United States, surpassed only by Lake Meade further downstream.

[00:04:48]The filling took an astonishingly long time. It was not until the 1980s that Lake Powell finally reached its full capacity for the first time. Over roughly 16 years, as the reservoir rose, the water climbed steadily up through Glen Canyon, drowning it level by level.

[00:05:08]The flooding submerged around 186 mi of the Colorado River's main channel. And it did far more than that. It drowned the treasures that made Glen Canyon so special.

[00:05:21]An estimated 125 major side canyons disappeared beneath the surface, each with its own hidden wonders, its own arches and aloves and streams, all of it lost to the depths.

[00:05:35]Among the countless treasures swallowed by the rising lake, one in particular came to symbolize everything that had been lost. It was a place called Cathedral in the Desert.

[00:05:46]And here is the great tragedy at the heart of this story. the thing that gives it such an aching poignency.

[00:05:53]Almost no one ever got to see Glen Canyon before it was gone.

[00:05:58]The dam was completed in 1963, and the water rose through the following years, which meant that the window to experience this magnificent landscape was vanishingly brief.

[00:06:09]Only a relative handful of people, riverr runners, explorers, photographers, a few determined travelers, ever laid eyes on the full glory of Glen Canyon before it slipped beneath the waves.

[00:06:24]For everyone who came after, it existed only in a scattering of photographs and in the wistful memories of those who had been there.

[00:06:32]An entire lost world described by those who saw it as a kind of paradise was drowned before the wider world ever had the chance to know it. For decades that seemed to be the end of the story.

[00:06:47]Glen Canyon was gone, sacrificed for water and power, sleeping beneath hundreds of feet of still green water.

[00:06:56]The people who had loved it mourned it and assumed reasonably that they and their children and their grandchildren would never see it again. It was, they believed, gone forever.

[00:07:09]But nature and a changing climate had other plans because the water that drowned Glen Canyon was about to begin disappearing.

[00:07:19]The Great Drying.

[00:07:21]Starting around the year 2000, something began to happen across the American Southwest that would slowly dramatically change everything.

[00:07:31]The region entered a period of extreme and prolonged drought. A drought so severe and so longasting that scientists have described it as a mega drought. And this was no ordinary dry spell.

[00:07:45]Researchers studying the climate history of the region using tree rings and other records stretching back over a thousand years have concluded that this drought is the most severe the American Southwest has experienced in around 1,200 years.

[00:08:00]Not since the medieval period has this land been so dry for so long. The Colorado River, the artery that feeds Lake Powell, carries its water from mountain snowpack far upstream.

[00:08:12]And as the warming climate reduced that snow pack and intensified the idity, less and less water flowed down into the reservoir.

[00:08:21]At the same time, the demand for that water never stopped.

[00:08:25]The cities and farms of the southwest continued to draw enormous quantities of water from the Colorado River system.

[00:08:32]And here lies the fundamental brutal arithmetic of the crisis. As those who study it have bluntly explained, the basin is using more water than naturally flows into the river. The great reservoirs Lake Powell and Lake me were built to catch and store excess water. But in a mega drought with relentless demand, there is no more excess water to catch.

[00:08:58]The result was inevitable.

[00:09:01]Lake Powell began to shrink. The water level, which had once climbed triumphantly up the canyon walls, began to retreat back down them, and the drop was dramatic. By the spring of 2023, the reservoir had fallen to a historic low, dipping to levels not seen since the 1960s, when it was still originally filling, an elevation of around 3,520 ft, some 180 ft below its full level.

[00:09:31]If you visit Lake Powell today, the evidence of this decline is written starkly across the landscape in what people call the bathtub ring.

[00:09:40]It is a pale bleached band of mineral stain running along the red canyon walls, marking the level where the water used to be.

[00:09:48]High above the current surface of the reservoir, that ghostly white ring traces the outline of a fuller lake that no longer exists.

[00:09:57]a haunting visual record of just how much water has vanished. But as devastating as this drought has been for the water supply of the Southwest, and make no mistake, it is a genuine and serious crisis. It has had one utterly unexpected consequence.

[00:10:16]As the water pulled back level by level, it began to uncover the drowned world it had hidden for 60 years.

[00:10:24]Glenn Canyon was starting to come back.

[00:10:28]What the water gave back. As Lake Powell receded, something began to happen that almost no one alive had ever witnessed.

[00:10:37]The lost canyons of Glen Canyon started to reappear, rising back into the sunlight one by one after decades beneath the water.

[00:10:46]It happened gradually as the surface of the reservoir dropped foot by foot.

[00:10:51]First, the highest features to emerge were the tops of canyon walls and the upper reaches of side canyons that had been just below the surface.

[00:11:00]Then, as the water kept falling, more and more of the drowned landscape was revealed.

[00:11:06]Side canyons that had been completely submerged for decades opened up again.

[00:11:11]Sandbarss and beaches emerged along the shrinking shoreline, and deep in the maze of Glen Canyon's tributaries.

[00:11:20]The hidden wonders that had made the place legendary began astonishingly to return. The features that emerged were breathtaking.

[00:11:29]Deep red rock canyons cradling lush ecosystems, otherworldly natural arches, caverns and al coes carved into the glowing sandstone and waterfalls.

[00:11:42]Real flowing waterfalls spilling over sandstone ledges into pools that had until recently been buried under the still waters of the reservoir.

[00:11:53]Places that had existed only in old photographs and fading memories were suddenly, impossibly real again, open to be walked into and touched and stood beneath. And there was a strange, almost eerie quality to this reemergence.

[00:12:09]Because when these canyons came back, they did not come back as ruins. In many cases, they came back looking remarkably like their old selves. The fundamental architecture of the stone unchanged. the waterfalls flowing once more as if they had never stopped. The rock had endured.

[00:12:28]Sandstone that had taken millions of years to form was hardly troubled by 60 years underwater.

[00:12:34]So, as the reservoir drained away from these features, what was revealed was in its bones the same landscape that had been drowned all those decades ago.

[00:12:44]People began making the journey out to witness it. Hiking down muddy creek beds at the bottom of canyons that had been deep underwater just a short time before, rounding a bend in the red rock and coming face to face with a cavern or a waterfall that no living person had seen in generations. Those who experienced it described being rendered speechless, falling silent in a kind of awe, struggling to comprehend that the beautiful living place they were standing in had so recently been at the bottom of a lake. But of all the wonders that returned as the water fell, one held a special significance.

[00:13:22]One was the crown jewel of Glen Canyon, the single feature whose loss had been mourned above all others, and whose return would move people most deeply of all. It was the Cathedral in the Desert, and it was coming back. The Cathedral Returns.

[00:13:39]To understand why the return of the Cathedral in the desert meant so much, you have to understand what this place actually is. because it is quite simply one of the most stunning natural formations on the face of the earth. The cathedral in the desert is a natural stone chamber, sometimes described as an amphitheater, located at the head of a canyon off the Escalante River, one of the tributaries of the drowned Colorado.

[00:14:08]Imagine a giant slot canyon. One of those narrow, sineuous cracks in the rock that the desert southwest is famous for. But instead of staying narrow from top to bottom, this one opens up near the canyon floor into an enormous soaring cavern.

[00:14:26]A vast curving chamber of red sandstone, its walls sweeping upward and inward like the vated ceiling of a great church. And at the head of this chamber, a gentle waterfall spills over a sandstone shelf, falling into a small, tranquil pool below. Its sound echoing and reverberating across the curved stone walls. It earned its name honestly.

[00:14:50]Standing inside it genuinely feels like standing inside a cathedral. A hushed hallowed sacred space, but one built not by human hands over centuries, but by water and stone over untold millennia.

[00:15:05]People who visited it before the flood described it in reverent, almost religious terms.

[00:15:11]It was without question one of the crown jewels of Glen Canyon, an iconic landmark that came to represent everything that was extraordinary about the place.

[00:15:22]And when Lake Powell filled, the cathedral in the desert was drowned, buried at times under something approaching 100 ft of water.

[00:15:32]For decades, this magnificent chamber sat silent and submerged. Its waterfall stilled, its sacred space filled with the dark water of the reservoir.

[00:15:44]For those who remembered it, its loss was almost unbearable.

[00:15:49]The cathedral's return has been a slow, dramatic, onagain, offagain affair, tied directly to the rising and falling of the reservoir.

[00:15:59]It made a brief partial appearance around 2005 when water levels dipped only to be submerged again. It began to emerge once more around 2019.

[00:16:10]And then as the mega drought drove the reservoir to its historic lows by 2023.

[00:16:16]The cathedral finally returned in earnest.

[00:16:19]At the record low water levels, the whole chamber was revealed. the full sweep of the sandstone amphitheater, the waterfall flowing once again over its shelf, the pool at its base.

[00:16:32]Visitors reported that as they approached, they could hear the sound of the falling water before they could even see it echoing out of the chamber exactly as it must have a lifetime ago.

[00:16:42]Standing inside the reborn cathedral after it had spent decades at the bottom of a reservoir was for many people an overwhelming emotional experience.

[00:16:52]Here was a wonder that had been declared lost forever, that people had genuinely believed they and their descendants would never see again.

[00:17:01]And there it was, restored, its waterfall singing as if it had simply been waiting patiently in the dark for the water to let it go. Life comes back faster than anyone expected. One of the most astonishing discoveries as the drowned canyons resurfaced was just how quickly life returned to them.

[00:17:24]Scientists and observers had wondered what these places would look like after decades underwater.

[00:17:30]Whether they would come back as sterile, muddy, lifeless scars.

[00:17:35]Instead, what they found was restoration happening at a speed that stunned even the experts.

[00:17:42]Consider the cathedral in the desert itself.

[00:17:45]After it reemerged and after a couple of years of low water combined with the region's seasonal monsoon rains, something important happened. The flowing water and the rains scoured away sediment that had accumulated on the chamber floor. In one account, some 20 ft of built-up sediment was washed away, further revealing the more natural original form of the cathedral. The canyon was in effect cleaning itself, flushing out the debris of its drowning and restoring its true shape. And then came the green. As the cathedral and the surrounding canyons dried out and stabilized, plant life began to return, and it returned with remarkable speed.

[00:18:27]In the cathedral in the desert, observers documented the return of maiden hair ferns. The same delicate hanging garden ferns that had made Glen Canyon's aloves so magical before the flood along with cottonwood trees, grasses, and willows.

[00:18:44]The lush living character of the old Glenn's was reasserting itself, reclaiming spaces that had been underwater for decades.

[00:18:53]In other parts of the receding reservoir, the transformation was even more complete. In some side canyons that had been out of the water for 20 years or more, the recovery was so total that it became genuinely difficult to tell a reservoir had ever been there at all.

[00:19:09]Visitors to these canyons could walk among tall cottonwood trees and full groves of willows. a thriving desert ecosystem that had rebuilt itself so thoroughly that the memory of the drowning had all but vanished from the landscape.

[00:19:23]As one observer put it, in these places, restoration was happening far faster than a lot of people had ever thought possible. This is a genuinely hopeful and beautiful thing to witness. It speaks to the extraordinary resilience of nature. The way that life, given even the smallest opening, comes rushing back.

[00:19:44]These canyons had been drowned for a human lifetime.

[00:19:48]And yet, within just a few years of being freed from the water, ferns were unfurling, cottonwoods were rising, waterfalls were flowing, and the secret glenns of Glen Canyon were becoming once again the living oases they had been before the dam.

[00:20:04]People began describing it as watching Glen Canyon come back to life before their very eyes.

[00:20:10]The footage no one thought they'd see for 60 years.

[00:20:15]Glen Canyon existed for most of the world, only in a handful of old photographs taken before the flood. The generation that had seen it firsthand was passing on and their images were fading into history.

[00:20:28]And then suddenly, as the water pulled back, there was a chance to document the resurrected canyon with modern cameras in vivid detail and to share it with millions of people who had never known it existed.

[00:20:42]And people seized that chance.

[00:20:45]Conservationists, journalists, photographers, filmmakers, and social media creators began making the journey out onto the shrinking reservoir and into the re-emerging canyons, cameras in hand.

[00:20:58]They motored across the still water to the mouths of side canyons, then hiked up the muddy creek beds into the heart of the resurfacing landscape, filming everything. The bathtub rings on the canyon walls, the newly revealed beaches, the flowing waterfalls, and the reborn cathedral in the desert with its echoing chamber.

[00:21:20]For the first time, highquality footage of this lost world began to circulate widely, letting people everywhere witness something that just a few years earlier would have been impossible. Among the most passionate documentarians of this reemergence have been members of the Glen Canyon Institute, an organization dedicated to the canyon, whose representatives have guided journalists and cameras through the returning landscape. Their executive director, Eric Balkan, has spent a great deal of time in the resurfacing canyons and has been a powerful voice describing what is happening.

[00:21:56]He has called Glen Canyon a kind of lost national park, a place unlike anywhere else. and watching it reappear, he described it as a generational opportunity, a rare, precious chance to witness a drowned wilderness returning to life and to take stock of the extraordinary natural wonders emerging from the depths.

[00:22:18]That phrase captures something real. For most of the past 60 years, seeing Glen Canyon in its full glory was simply impossible. Now, for a window of time, it has become possible again. And thanks to modern cameras, that window has been thrown open to the entire world.

[00:22:37]People who will never make the journey themselves can now see in stunning detail the waterfalls and caverns and the great stone cathedral that emerged after six decades underwater.

[00:22:49]But, and this is where honesty demands a turn in the story, not everything that emerges from a receding reservoir is beautiful.

[00:22:59]As the water pulls back, it reveals not only wonders, but also darker and more sobering things. And it forces us to confront an uncomfortable truth about why all of this is happening in the first place.

[00:23:14]What the receding water also reveals.

[00:23:17]The falling water of Lake Powell has uncovered natural wonders, yes, but it has also uncovered evidence of human tragedy and reminders of the very crisis that is causing the water to disappear.

[00:23:29]As the reservoir has shrunk, it has exposed areas of the lake bed that had been submerged for years. And in some of those areas, grim discoveries have been made. In one sobering case, the receding water helped lead to the recovery of the body of a man who had gone missing, found in a vehicle that had become submerged in the lake.

[00:23:50]As the water levels dropped, areas that had been hidden underwater were exposed and long lost things, including the traces of accidents and disappearances, began to surface.

[00:24:02]It is a stark reminder that a reservoir is not only a place of recreation and beauty, but also sometimes a keeper of secrets and losses.

[00:24:12]These discoveries carry a heavy symbolic weight. The same falling water that reveals the reborn cathedral in the desert also reveals sunken cars and long hidden tragedies.

[00:24:23]The reservoir, as it empties, gives up all of its secrets at once, the wondrous and the sorrowful alike. And every one of these revelations, beautiful or grim, is a direct consequence of the same underlying reality.

[00:24:39]There is far less water than there used to be, and the great reservoir is emptying out.

[00:24:45]That reality is the shadow that falls across this entire story. Because as genuinely moving as it is to see Glen Canyon returning, we have to be honest about why it is returning. It is not returning because someone chose to restore it. It is returning because the American Southwest is running out of water. The reemergence of these canyons is a direct symptom of a severe and dangerous water crisis. One that threatens the water supply and the hydroelectric power of tens of millions of people across the region. The beauty and the crisis are two faces of the exact same event.

[00:25:23]The uncomfortable truth beneath the beauty.

[00:25:26]So, here's where I have to be completely honest with you, because this story is often told as a simple feel-good tale of nature triumphantly returning, and the truth is far more complicated and far more sobering than that. Yes, the reemergence of Glen Canyon is genuinely beautiful. Yes, the speed of the ecological recovery is a real and hopeful demonstration of nature's resilience. Those things are true and they are worth celebrating.

[00:25:54]But they are inseparable from a crisis that is anything but beautiful.

[00:25:59]The only reason these canyons are resurfacing is that a 1200year mega drought intensified by a warming climate and worsened by decades of overconumption is draining the water supply of an entire region.

[00:26:13]The very sight that inspires such wonder is at the same time a flashing warning sign of profound trouble.

[00:26:21]And there is a further poignant complication.

[00:26:24]The return of Glen Canyon is not guaranteed to last because the reservoir does not simply keep falling. Its level rises and falls with the weather.

[00:26:35]In years of good snowpack, the water comes back. In fact, this has already happened.

[00:26:42]After a big winter of snow, water managers chose to store much of that runoff in Lake Powell. And as the reservoir rose, some of the re-emerged wonders were drowned all over again. The cathedral in the desert, having triumphantly returned, was partially refflooded. Its chamber, once more slipping beneath the rising water.

[00:27:02]People who had celebrated its return, had to watch it vanish a second time.

[00:27:07]The canyon exists now in a kind of limbo, emerging and submerging with the cycles of drought and snow. Its fate uncertain from year to year.

[00:27:18]This creates a genuinely difficult tension, and thoughtful people disagree about how to feel about it. For those who love Glen Canyon and mourn its drowning, its reemergence is a bittersweet miracle. And some argue passionately that the canyon should be allowed to stay revealed, restored, and free. For those who depend on the reservoir's water and power, again, tens of millions of people, a full Lake Powell is essential, and its decline is a genuine emergency.

[00:27:50]There is no simple villain and no simple hero here.

[00:27:54]There is a real hard conflict between the restoration of an irreplaceable natural wonder and the water security of the modern Southwest.

[00:28:02]And honesty requires holding both of those truths at once without pretending the beauty erases the crisis or that the crisis erases the beauty. That is the real complicated human truth beneath the stunning footage.

[00:28:18]Which brings us finally to what this reemergence truly means.

[00:28:24]the real revelation.

[00:28:26]So, let us return to where we began and ask what really emerged from beneath Lake Powell after 60 years underwater.

[00:28:34]It was not a monster and it was not a secret. And it was not some supernatural mystery pulled from the deep. What emerged was something far more powerful and far more real. a lost world, a drowned wilderness of redstone and hidden waterfalls, and a sacred natural cathedral.

[00:28:54]Returning to the sunlight after six decades of burial, and with it emerged something even larger, a profound and uncomfortable message about the relationship between human beings in the natural world, and about water, the most precious resource of all.

[00:29:13]Because the true revelation of the emptying reservoir is this.

[00:29:17]60 years ago, we looked at a place of almost unimaginable beauty and decided without much hesitation to drown it. To trade a paradise for water and power, confident that we could bend the great river to our will and store its water forever behind a wall of concrete.

[00:29:35]For a while, it seemed to work. But nature in the end does not simply submit to our engineering. The mega drought has revealed the limits of that confidence exposing the hard truth that we have been using more water than the river can provide. And as that reality has drained the reservoir, it has almost as a kind of message uncovered the very wonder we thought we had erased.

[00:30:03]There is something almost mythic in it.

[00:30:06]The drowned cathedral rising again from the depths. Its waterfall singing once more, not as a triumph we engineered, but as a consequence of a crisis we failed to prevent. It is beautiful and it is terrible all at once. It is a reminder of what was lost, a demonstration of nature's astonishing power to heal, and a warning about the unsustainable path that revealed it, all bound together in a single breathtaking sight. That is what emerged from beneath Lake Powell.

[00:30:40]Not just a canyon, but a reckoning. A stunning silent testament to the fact that the natural world we bury does not always stay buried and that the choices we make about water in an age of drought and a changing climate will shape everything. The cathedral in the desert stands revealed once more. Its ancient stone patient and enduring, waiting to see what we will do next. And whether it remains in the light or slips beneath the water once again depends on choices that are still for now ours to make.
