Chuck Pratt

Charles Marshall Pratt (March 5, 1939 – December 16, 2000) was an American rock climber known for big wall climbing first ascents in Yosemite Valley. He was also a long-time climbing instructor and mountain guide with Exum Mountain Guides in the Grand Tetons.

In August, 1958, he completed the first ascent of the north face of Fairview Dome in Tuolumne Meadows in Yosemite National Park with Wally Reed, This climb, completed when Pratt was 19, is described as "marvelously direct" and a "memorable climb" in Fifty Classic Climbs of North America.

In 1959, he completed the first ascent of the East Face of Washington Column (later called 'Astroman') in Yosemite Valley with Warren Harding and Glen Denny.

In 1960, he made the second ascent of The Nose on El Capitan in Yosemite Valley, a route pioneered by Warren Harding in 1958. He climbed with Royal Robbins, Tom Frost and Joe Fitschen, and they made the climb in one continuous push lasting seven days. Robbins said it was "the most magnificent and complete adventure of our lives." The first ascent had taken Harding's team 45 days of climbing spread over an 18-month period.
