In 10 thrilling real-life adventure stories, pioneering whitewater explorer Wick Walker examines what lured a generation of incredibly daring pioneers into some of Earth's most wondrous yet forbidding river canyons: below Victoria Falls on the Zambezi; the Great Bend of the Tsangpo in Tibet; Tiger Leaping Gorge on the Yangtze; the flanks of Mount Everest, and more. Loaded with great moments and personal stories, Walker details what these adventurers found there, and within themselves. The extraordinary characters, driven by different motives and visions, but united by their compulsion to seek the unknown and the pulse of free-flowing water, are as remarkable as the daunting geography and conditions they confront. Whitewater sport today stands side-by-side with mountaineering in participation and public attention, yet it has lagged in generating its own literature. TORRENTS AS YET UNKNOWN helps fill that gap for readers interested in human drama played out against great natural challenges. Mountaineering history is deep and its literature rich, but whitewater adventurers approach and experience the same forbidding terrain from a different vantage, between the steep walls of their canyons and atop powerful torrents of cascading water.
