Royal Robbins' accomplishments as rock climber and adventurer are legendary. An early advocate of boltless, pitonless clean climbing, he did much to transform the climbing culture to minimize the human impact on the vertical wilderness and protect its natural features. As a rock-climbing pioneer, he broke through existing standards to create wholly new skill and difficulty levels. In the 50's, 60's and into the 70's, Robbins established one daring new climb after another, among them many revered classics on Yosemite's Half Dome and El Capitan., ISBN13: 9780910856348 ISBN10: 0910856346 Material Type: paperback
