This is the 2013 special anniversary edition to commemorate the 50th anniversary of the first ascent of Mount Everest via the West Ridge which remains the least attempted and most deadly of recognised routes on Everest. In 1963, Jim Whittaker became the first American to summit Everest via the South Col route. Roughly two weeks after Whittaker's achievement, Tom Hornbein and Willi Unsoeld, fellow American mountaineers on the same expedition, became the first climbers ever to summit the world's highest peak via the dangerous and forbidding West Ridge - a route on which only a handful of climbers have since succeeded. This special 50th anniversary edition reintroduces the adventure in a larger format with full-colour photographs by members of the expedition, including leader Norman G. Dyhrenfurth and team doctor Jim Lester. In addition to a new foreword by Jon Krakauer, this volume also features a new preface by Hornbein along with a series of prefaces he wrote for earlier editions, including the original from 1965, and a map by Dee Molenaar.Updated bios of all the American Mount Everest Expedition team members, written by climber Broughton Coburn, are now accompanied by contemporary portraits from the expedition.
