Mount McKinley. Bill Krause, Ted Waltman and Mike Danaher in alpine style made the fourth ascent of the East Buttress, reaching the summit on June 8 before descending the West Buttress. They had very severe weather conditions on this difficult route. They were nine days on the East Buttress and then were pinned down by storms for days on the upper slopes of the peak. In May Gary Bocarde and others made the second ascent of the Northwest Buttress.
