Ascents in Avalanche Canyon. In June and July Graham and Mary Ann Matthews climbed from Avalanche Canyon. They made the ascent of an unnamed pinnacle east of Mt. Wister, quite obvious from the highway but evidently not previously climbed. A fine climb was that of the south face of Cloudveil Dome, a route that had long attracted attention. It turned out easier than expected, but offered varied and interesting climbing from class 3 to class 6.
