North America, United States, Wyoming, Tetons, Crooked Thumb, West Ridge, Tetons

Crooked Thumb, West Ridge, Tetons. Robert Irvine and Tom Kimbrough climbed this distinct ridge on July 28 in nine pitches plus considerable scrambling. From the drainage separating this ridge from the prominent northwest ridge of Teewinot, a considerable distance of exposed but unroped climbing brought them to the beginning of the route, just above the base of the ridge. The first full rope-length lead was very steep and unprotected, up loose rock and beset with rockfall. The remainder of the ridge varied from moderate to difficult. The next to last pitch was a full rope-length of F6 on steep, enjoyable rock. (III, F7.)
