From the smoking volcanoes of South America to the great snowy ranges of the Himalaya, The White Ladder follows a cast of extraordinary characters—conquistadors and captains, scientists and surveyors, alpinists and adventurers—up the slopes of the world's highest peaks. A masterpiece of edge-of-your-seat narrative history, The White Ladder describes the epic rise of mountaineering's world altitude record, a story of ever higher climbs by figures great and small of mountaineering. Daniel Light describes how climbers used revolutionary techniques to launch themselves into the most forbidding conditions. The expeditions illustrate evolutionary changes in climbing style, the advancement of high-altitude science, and the development of mountain climbing as an industry. Throughout, Light pays special attention to Incan climbers, Gurkha guides, Sherpa mountaineers, and many others who are often overlooked. He offers nuanced new perspectives on familiar characters, including Fanny Bullock Workman, Aleister Crowley, and Oscar Eckenstein. A story of innovation, invention, and determination, this book immerses listeners in a fascinating historical period. With their breathtaking exploits, these climbers laid the groundwork for the historic ascents of K2 and Everest that came after—and heightened the spectacle of their dangerous sport.
