The Top of Everest1 / 9

Part One · The Mountain

Mount Everest, which rises along the frontier between Nepal and Tibet, is the highest mountain on the planet, and its summit towers roughly twenty-nine thousand feet above the level of the sea. For centuries the people who lived in its shadow had regarded it as a sacred peak, but during the early twentieth century it became an irresistible challenge for mountaineers from other countries as well. Numerous expeditions attempted the ascent between the 1920s and the 1950s, and every one of them either retreated or ended in tragedy. The atmosphere near the top contains only about a third of the oxygen available at sea level, the winds are ferocious, and temperatures can plunge far below zero. By 1953 the mountain remained unclimbed, and many experts suspected that it was simply impossible.
