A thrilling chronicle of the tragedy-ridden history of climbing K2, the world's most difficult and unpredictable mountain, by the bestselling authors of "No Shortcuts to theTop "At 28,251 feet, the world's second-tallest mountain, K2 thrusts skyward out of the Karakoram Range of northern Pakistan. Climbers regard it as the ultimate achievement in mountaineering, with good reason. Four times as deadly as Everest, K2 has claimed the lives of seventy-seven climbers since 1954. In August 2008 eleven climbers died in a single thirty-six-hour period on K2-the worstsingle-event tragedy in the mountain's history and the second-worst in the long chronicle of mountaineering in the Himalaya and Karakoram ranges. Yet summiting K2 remains a cherished goal for climbers from all over theglobe. Before he faced the challenge of K2 himself, Ed Viesturs, one of the world's premier high-altitude mountaineers, thought of it as "the holy grail of mountaineering." In "K2: Life and Deathon the World's Most Dangerous Mountain, " Viesturs explores the remarkable history of the mountain and of those who have attempted to conquer it. At the same time he probes K2's most memorable sagas in an attemptto illustrate the lessons learned by confronting the fundamental questions raised by mountaineering-questions of risk, ambition, loyalty to one's teammates, self-sacrifice, and the price of glory. Viesturs knowsthe mountain firsthand. He and renowned alpinist Scott Fischer climbed it in 1992 and were nearly killed in an avalanche that sent them sliding to almost certain death. Fortunately, Ed managed to get into a self-arrestposition with his ice ax and stop both his fall and Scott' s. Focusing on seven of the mountain's most dramatic campaigns, from his own troubled ascent to the 2008 tragedy, Viesturs and Roberts crafts anedge-of-your-seat narrative that climbers and armchair travelers alike will find unforgettably compelling. With photographs from Viesturs's personal collection and from historical sources, this is the definitive account ofthe world's ultimate mountain, and of the lessons that can be gleaned from struggling toward its elusive summit.
