Mount McKinley. There were nine successful expeditions which climbed Mount McKinley in 1971. Ten expeditions attempted the climb unsuccessfully. There were two fatalities, one at 9300 feet on the Muldrow Glacier and one at 16,000 feet on the West Buttress. Of the 163 climbers, 48 made the summit and 115 did not. The French climb of the Cassin route variation is covered by an article. Gary Ullin, Michael Sloan, Jack Cole, James Foster and Ronald Mucke were the only party to climb the North Peak as well as the South (main) Summit, ascending Pioneer Ridge and descending Karstens Ridge.

Mount McKinley Correction. Inadvertently we omitted the name of Carolyn Smith, who accompanied her husband Ronald Smith and others to the summit of Mount McKinley on July 20, 1970, in A.A.J., 1971, 17:2, p. 325. We congratulate Mrs. Smith on this rugged ascent.
