Aron Ralston

Aron Lee Ralston (born October 27, 1975) is an American mountaineer, mechanical engineer, and motivational speaker, known for surviving a canyoneering accident by cutting off part of his right arm. On April 26, 2003, during a solo descent of Bluejohn Canyon in southeastern Utah, he dislodged a boulder, pinning his right wrist to the side of the canyon wall. After five days, he had to break his forearm, amputate it with a dull pocket knife to break free, make his way through the rest of the canyon, rappel down a 65-foot (20 m) drop, and hike 7 miles (11 km) to safety. The incident is documented in Ralston's autobiography Between a Rock and a Hard Place and is the subject of the 2010 film 127 Hours where he is portrayed by James Franco.
