Amos Richards was hiking alone in the Canyonlands National Park in Utah when he fell, broke his leg and dislocated his shoulder.
"It took me about 3 or 4 minutes to work my shoulder and get it back in place, and once I got it back in place, I stood up and realized my ankle hurt a little bit," Richards said.
He had no cellphone service and only two protein bars to eat.
Richards had to crawl nearly five miles across the desert for four days before he was finally rescued. He said the worst part was when the sun went down.
"It was so miserable at night, so cold. It was only down in the upper 50s probably, but I only had short pants and a short-sleeved shirt. It was just so miserable that I couldn't stand the thoughts of another night down there," he said.
He was stuck in the same canyon where climber Aron Ralston was trapped and forced to cut off his arm to free himself. Ralston's story was later adapted into the Oscar-nominated movie, "127 Hours."
Richards says he was inspired to hike at this particular spot after watching that movie.
