On April 26, 2003, Aron Ralston was canyoneering alone through Bluejohn Canyon, in eastern Wayne County, Utah, just south of the Horseshoe Canyon unit of Canyonlands National Park. He Was Trapped In A Canyon For 127 Hours and had to drink his own urine and amputate his arm to survive. He furthermore became a motivational speaker and wrote a book called between a rock and a hard place. This became a bestseller and was turned into a movie called 127 hours.
