From 2004: Adventurer Aron Ralston, who cut off his own arm to save his life after getting trapped by a boulder in a Utah canyon, describes his six-day 2003 ordeal to Tom Brokaw. Ralston was hiking by himself in Utah's Canyonlands National Park when he got stuck in remote Blue John Canyon---and after five days was left with only one choice if he wanted to live. He doesn't expect to be treated as a hero. “I did what I needed to do,” he says simply.
