California—Mt. Shasta: About August 1, 1952 unroped but in the company of a friend, Carl Miller, Dan O’Neill (34) attempted to ascend Mt. Shasta. At about 12,000 feet O’Neill slipped on a steep snow slope and slid head first nearly a mile in distance. He suffered only minor lacerations'and snow burns of his arms. He apparently was able to maintain steerage way and so to avoid two outcroppings of rocks. He and his companion negotiated the rest of the descent uneventfully.
