chunk: Ralston realizes that by his knowledge of applying torque, he can break the radius and ulna, letting him amputate his arm in order to escape. He fashions a crude tourniquet out of CamelBak tube insulation, uses a carabiner to tighten it, and cuts tissue soon to his success. He wraps the stump of his arm to prevent exsanguination and takes a picture of the boulder. He then rappels down a 65-foot rockface using his other arm, and drinks rainwater from a small pond in the hot midday sun. During his miles-long hike for help, he stops to admire the Great Gallery at the Horseshoe Canyon (Utah). He meets a family on a day hike, who alert the authorities to Ralston's presence, and a Utah Highway Patrol helicopter is dispatched. Ralston is taken to a hospital where he recovers, and is fitted with a prosthesis, and continues his hobbies of climbing canyons and mountains, along with starting a family of his own.
