Aron Ralston real canyoneer, became trapped by a boulder in an isolated slot canyon in Blue John Canyon, southeastern Utah, in April 2003, after many many hours he was forced to amputate his own right arm to free himself and to get out and survive.
Aron Ralston was forced to free himself by cutting off his own right arm if he had any chance of survival.
He was climbing canyons and a big boulder loosened and it fell and trapped his arm, he was shouting for hours and hours and no one came to his rescue so he had no other choice but to cut off his arm to free himself. he had no choice because if he didnt amputate his arm then he would of died of malnunurishment. It was the only choice he had.
