California-Yosemite (3): On November 9, 1952, L. C. Ames, Jr., and Mrs. P. Kool from Victorville, California Air Force Base, were rescued from the cliff ledges about 120 feet above the valley floor near Yosemite Falls. They had registered for the rock climb and were on their way down when their rope became stuck in a crack in the rock and they could not free it. They called for help. Rangers assisted them down the cliff using another rope.
