On June 8, 1924, George Leigh Mallory and Andrew Irvine disappeared somewhere near the summit of Support Everest, leaving open the tantalizing question of if they had reached the summit of Everest twenty-nine years before Edmund Hillary and Tenzing Norgay. In 1999, climber Conrad Anker discovered Mallory’s body on Everest and helped solve one of the greatest mysteries in the annals of experience and exploration. In The Lost Explorer, Anker and historian David Roberts build a dramatic accounts from the expeditions of 1924 and 1999, and ultimately capture the enthusiasm and soul of two men driven to check themselves against nature at its most brutal.
