Dr John All, a geography lecturer from West Kentucky University who specialises in mountain science was collecting snow samples on the 23,379 feet Mount Himlung, close to Mount Everest in the Nepal Himalaya, when he fell into a deep crevasse which had been hidden by recent heavy snow.
His body ricocheted between the walls of the crevasse as he fell before he landed on a precarious ice ridge 70 feet down but more than 300 feet from the bottom. He spent the next six hours in agony crawling inch by inch with his ice axe, knowing that at any moment one slip and he would fall to a certain death.
