Gripping and sumptuous, this is the definitive book on the history, mystique, and science of Mount Everest, including how climate change is impacting the world’s tallest mountain. In 1963, the American Mount Everest Expedition made mountaineering history. It was the first American venture to successfully scale the legendary peak and the first successful climb up the hazardous West Ridge (a climb so difficult no one has yet repeated it). In 2012, adventurer Conrad Anker led a National Geographic/The North Face team up the mountain to enact a legacy climb. Environmental changes and overcrowding led to challenges and disappointments, but yet the mountain maintains its allure. Now, steely-eyed Anker leads a team of writers in a book designed to celebrate the world’s most famous mountain, to look back over the years of climbing triumphs and tragedies, and to spotlight what has changed–and what remains eternal–on Mount Everest. Telltale signs of Everest’s current state, never-before-published photography, and cutting-edge science expose the world’s tallest peak–its ancient meaning, its ever-present challenges, and its future in a world of disappearing ice.
