The Lost Explorer

On 8 June 1924, George Leigh Mallory and Andrew 'Sandy' Irvine were last seen climbing towards the summit of Everest. In 1999, Conrad Anker found the body of Mallory on Mount Everest. This title assesses the clues provided by the body, its position, and the possibility that Mallory had successfully climbed the Second Step, a 90-foot sheer cliff.
