Colorado: Snowmass Peak (14,077 ft.). On 26 August 1949 Arthur Gallager (21), a Yale student from Colorado Springs, slid to his death in a rock slide. Eye-witnesses said that he slipped from a ledge while he was descending from a summit of the peak and fell 30 feet onto a steep area of loose boulders, etc., where his weight precipitated a rock slide. This in turn carried him 150 feet down the mountain. He was engulfed by the rolling, sliding blocks of rock and evidently crushed to death. A ten-man rescue party brought the body down two days later.

Analysis. Because details are inadequate, no full attempt at an analysis of this accident is made. We point out only that a loose rock avalanche can be even more dangerous than one of snow, because of the tremendous weight and the sharp edges of the large individual blocks.
