A Western Kentucky University professor is recovering from serious injuries after hiking on a research trip and surviving a harrowing, 70-foot fall into an ice crevasse in Nepal.
John All, 44, used an ice axe and one arm to fight his way back to the surface, making an epic climb in freezing temperatures from the depths of the icy hole in a brave act that saved his life, the New York Daily News
Badly injured with broken ribs, a broken arm and dislocated shoulders, All
struggled for six hours to reach the surface and get to a tent where he stayed overnight and called for help.
All's terrifying odyssey was captured on several videos that he posted on Facebook
. In them, the hiker – his face bloodied and bruised – shows himself deep in the crevasse, in shock and pondering death alone on a snowy Himalayan mountain.
"I thought I was going to die, there was no way out," All told reporters from his hotel in Katmandu, where he is now recovering from his injuries. "I was all alone."
All, an associate professor
of geography at WKU, was a part of a team of researchers studying pollution and global warming who were collecting samples from Mount Himlung. But he was two days ahead of his team when he slipped into an open crack in the ice, plunging until a ledge stopped his dive.
After his desperate climb up and out, All called for help on a GPS device he was carrying, but he had to spend the night on the cold mountain until a helicopter could swoop in and take him to a hospital.
All, a photographer and alpinist who holds an international environmental law degree along with his doctorate in global climate change, told reporters he remains undaunted and hopes to climb again on a June trip to Peru.
