In April 2003, Aron Ralston was on a solo climbing trip in Utah’s Canyonlands National Park when an 800-pound boulder suddenly fell from above him. The next thing he knew, his right arm was lodged between the boulder and a canyon wall. Quite literally caught between a rock and a hard place, Ralston was also trapped 100 feet below the desert surface and 20 miles away from the road.
