California, Yosemite (3)—On August 29, 1956 Ronald W. Beck (19), fell about 150 feet and was killed while attempting to climb Grizzly Peak near LeConte Gully, off from the Sierra Point trail. He had removed his shoes and tried to cross a smooth section of rock when he slipped and fell to a ledge below. He was accompanied by two other young men on this climb but his companions did not witness the fall.
