he fell into the freezing Salt River with his snowmobile. Unable to move any farther, Gardner decided to build a shelter and wait for a rescue team. He remained stranded for the next 18 hours. After several hours in his makeshift shelter, he stopped shivering, which led him to believe that he was dying. When he was eventually rescued, he was experiencing hypothermia and severe frostbite.
