Aron Lee Ralston is an American outdoorsman, mechanical engineer and motivational speaker known for having survived a canyoneering accident in southeastern Utah in 2003 during which he amputated his own right forearm with a dull pocketknife in order to extricate himself from a dislodged boulder, which had him trapped in Blue John Canyon for five days and seven hours . After he freed himself, he had to make his way through the remainder of the canyon, then rappel down a 65-foot sheer cliff face in order to reach 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 starring James Franco.
