John All, an associate geography professor at Western Kentucky University, was collecting snow samples on Mount Himlung in the Himalayas when he fell 70 feet into a crevasse.
All and his team are studying climate change and pollution on glaciers in Nepal. However, All went off on his own to get samples and was alone on the glacier when he fell.
"I went out to collect that data and scout that stuff, sort of not expecting anything at all," he told ABC News.
"[It was a] creepily flat glacier," he said. "So [I] went from walking along in a brilliant white snow field to suddenly plunging through a mine shaft and bouncing off the walls, starting with my face."
Determined to make it out alive, All recorded his journey.
"I took the video as sort of an affirmation. … I thought to myself that I'm going to get out of here and I want my family to be able to see what's happening and understand what my life and how I have to fight through some things is like," All said.
Despite having sustained a broken arm and ribs from the fall, All was able to climb out of the crevasse.
"It probably took me four or five hours to climb out. I kept moving sideways, slightly up, sideways, slightly up, until I found an area where there was enough hard snow that I could get an ax in and pull myself up and over."
Once back at his tent, Al radioed for a helicopter and was transported 16 to 18 hours later to a Kathmandu hospital.
