North America, United States, Alaska, McKinley, Rapid Ascent

McKinley, Rapid Ascent. On June 4 late in the afternoon, Mugs Stump left the camp at 14,000 feet on the West Buttress of McKinley and crossed to the West Rib, which he descended to the northeast fork of the Kahiltna. He then climbed the Japanese Couloir and the whole Cassin Ridge to the summit in 15 hours and descended to the 14,000-foot camp, which he reached just 27½ hours after he had left it.
