Scientist Fell 70-Feet Into A Deadly Crevasse And Recorded The Entire Thing

Dr. John All was clinging on for his life on a frozen ledge after he slipped into an icy deathtrap.

He was covered in blood, baldy bruised and battered all over, and there was still another 300-feet of darkness below him.

He was struggling to breathe and his arm was broken, but after seeing the blue sky 70-feet above him, he knew he had get out.
