Peterson v. Department of Labor & Industries

July 10, 1926, plaintiff was working as powder man in a quarry. After a round of shots had been fired, he was engaged in “barring down” rock loosened by the blast, at a point on the side wall of the quarry ninety feet above the floor. While thus engaged, a mass of loosened rock, consisting of several tons, gave way. The avalanche carried plaintiff with it to the floor of the quarry. When dug out of the debris, he was unconscious, and remained so for some hours. He was taken to a hospital, where he remained for two weeks. During the first two or three days, he was in a semi-conscious condition.
