127 Hours: The True Story of Aron Ralston's Incredible Canyon Survival

Somewhere in the depths of Bluejohn Canyon, 100 feet below the desert surface, a young man stands motionless. His right arm is wedged between an 800-pound boulder and the canyon wall. He cannot move. He cannot call for help. Nobody knows where he is.

It is April 26, 2003, the first day. Five more will follow. A total of 127 hours between life and death, in a canyon so narrow the sun never reaches the bottom. Aron Ralston — a 27-year-old engineer who quit his job to live in the mountains — will be forced to make a decision no one should ever have to face.

This story is not a movie script. Or rather, it became a movie later. But first it was reality. First it was blood, thirst, delirium, and a two-inch knife.

Aron Ralston was born on October 27, 1975, in Ohio. Growing up, his family moved to Colorado, where the young Aron discovered the world of climbing. He wasn't immediately obsessed. First he studied mechanical engineering at Carnegie Mellon University, graduating with top marks. He worked five years as an engineer. Good salary, stable life, predictable future.

But something pulled him elsewhere. The feel of rock beneath his fingers. The air at 14,000 feet. The silence of a summit few had reached. In 2002, he decided he'd spent enough time behind a desk. He quit his job, moved to Aspen, Colorado, and committed himself to mountaineering full-time.

His goal was audacious: to climb all 59 of Colorado's “fourteeners” — mountains exceeding 14,000 feet — solo, in winter. Nobody had ever recorded such a feat before.

On the evening of April 25, 2003, Ralston slept in his truck, parked somewhere in Canyonlands National Park, southeastern Utah. He was planning a day trip to Bluejohn Canyon — an 11-mile-long gorge so narrow in places that his shoulders could nearly touch both walls.

At 9:15 on Saturday morning, he got on his bicycle and rode 15 miles to the canyon entrance. He locked the bike. He carried a small backpack: a bottle of water, two burritos, some candy bar crumbs, a camera, and a cheap multi-tool — “the kind you'd get for free if you bought a $15 flashlight,” as he later described it.

There was, however, something he didn't bring: anyone else. And he hadn't told a soul where he was going. Not his parents, not his friends, not anyone. Ralston walked into the canyon alone, with the self-assurance of someone who believed wilderness was his second nature.

Around 2:45 in the afternoon, Ralston was deep inside the canyon, in a narrow passage. He pressed his feet and hands against the walls, descending slowly. Then a rock above him — a massive 800-pound boulder — shifted. It slid down together with Ralston. Within seconds, the boulder came to rest, pressing his right hand between the stone and the canyon wall.

Lightning-strike pain. Ralston looked down. His fingers already appeared bluish. The boulder wouldn't budge a millimeter. He tried pushing it with his shoulder — nothing. He chipped around it with his multi-tool — only tiny fragments. The rock was enormous, indifferent, merciless.

In the first minutes, Ralston experienced something close to panic. But then, his training — years of climbing, months alone on summits — forced him to think. He calmed down. He took stock of his situation: one bottle of water. Two burritos. A cheap knife. A camera. And five days until death.

The first night was the worst. Not because of the pain — that came later — but because of the cold. Temperatures in the canyon dropped dramatically after sunset. Ralston, wearing shorts and a T-shirt, shivering violently, realized dehydration would come quickly.

He ate a little each day. He divided the burritos into tiny bites. He rationed every sip of water. When the bottle ran dry — maybe the second or third day — he began drinking his own urine. The taste was horrifying, but the alternative was unmistakable: death.

Each day, Ralston tried something new. He struck the boulder with rocks. He dug around his hand. He tried using the knife as a lever. Nothing worked. The boulder did not move. His hand was slowly dying. After the third day, he had lost all sensation in his fingers.

At night, the frigid air made him shiver relentlessly. The days dissolved into a haze of thirst, pain, and exhaustion. The only way he managed to keep his sanity was the camera.

After four days trapped, Ralston became convinced he would not make it. He lifted the camera, looked into the lens, and recorded farewell messages. To his parents. To his friends. To every person he loved.

The words came out broken. His voice was thin, dehydrated, as if belonging to someone much older. He apologized for not telling anyone where he was going. He apologized for the reckless life he had chosen.

Then he took the multi-tool and carved into the canyon wall: his name, his date of birth, a probable date of death, and the letters RIP. His own epitaph, written by his own hands — or rather, by the only hand he could still move.

On the fifth night, Ralston sank into a restless sleep. Perhaps it was dehydration. Perhaps exhaustion. Perhaps something beyond reason. Whatever the cause, that night, he dreamed of himself.

In the dream, he was standing in a house. He was holding a small boy in his arms — his son. And the right arm was gone. In its place was a prosthetic limb. And Ralston, inside the dream, was happy.

He woke with a clarity he hadn't felt in five days. It wasn't merely hope — it was certainty. He would live. He would have a family. He would hold a child with one arm. But first, he had to remove the arm that kept him prisoner.

And then the revelation came. For days, he had been thinking about how to cut through the bone with a short knife. Impossible — the blade couldn't cut bone. But that morning, he understood: he didn't have to cut the bones. He could break them.

What followed can hardly be described. Ralston pressed his body against his trapped arm, using torque as leverage. Snap. The first bone — the radius — broke. Then, pressing from a different angle, the ulna. Two bones broken deliberately, methodically, by a half-dead man in a canyon.

With the bones disconnected, it was time for the soft tissue. Ralston fashioned a tourniquet from his CamelBak tubing. He cut off the blood circulation entirely. And then, with a two-inch knife — dull, cheap, absurd — he began cutting through skin, muscle tissue, and tendons. He used the multi-tool's pliers for the toughest tendons.

He left the arteries for last. He knew that once he severed them, the clock would start counting down.

The entire process took one hour. One hour during which Ralston lost 25 percent of his blood volume. One hour that he later described — paradoxically — as the greatest moment of triumph in his life.

Ralston stood up. For the first time in five days, he could move freely. Behind him, in the rock crevice, a part of himself remained — literally. Ahead of him, a series of obstacles that would stop most healthy people.

First, he climbed out of the canyon slot. Then he rappelled down a 65-foot vertical cliff — with one arm, bleeding, dehydrated, half-conscious. And finally, he hiked six miles through the desert heat, back toward his car.

Six miles into the hike, he encountered a family of Dutch tourists walking through the canyon. They stared at him in horror. They offered him Oreo cookies and water. And they called the authorities.

Canyonlands officials had already activated a search — Ralston had been reported missing — but the helicopters were searching the surface. A hundred feet below the desert, no helicopter would have ever found him.

Four hours after the amputation, Ralston was aboard a rescue helicopter. Doctors later said the timing couldn't have been more precise. Had he cut his arm sooner, he would have bled to death. Had he waited longer, he would have died in the canyon.

Between a rock and a hard place

After the rescue, 13 park rangers returned to the canyon to retrieve the severed forearm and hand. They needed a hydraulic jack and a winch to move the boulder. The arm was cremated and given back to Ralston. Six months later, on his 28th birthday, he returned to Bluejohn Canyon and scattered the ashes there.

His story traveled around the world. Ralston wrote the book “Between a Rock and a Hard Place,” which became a bestseller. In 2010, director Danny Boyle brought it to the big screen as “127 Hours,” with James Franco in the role of Ralston. Several audience members fainted during the amputation scene.

Ralston described the film as "so factually accurate it is as close to a documentary as you can get and still be a drama." The only difference, he said, was that the cutting scene lasted a few minutes instead of a full hour.

And the dream? It came true. Aron Ralston is now a father of two. He never stopped. In 2005, with a prosthetic limb, he became the first person to climb all 59 of Colorado's fourteeners — solo, in winter, one-handed.

Some say he was reckless. Perhaps. Some say he was brave. Certainly. What nobody disputes is this: alone in a canyon, without help, without hope, Aron Ralston found the strength to do what no rational person would ever want to contemplate — and lived to tell the tale.
