McKinley North Summit, Telemark Ski Descent of Wickersham Wall. Starting on May 5, Tyson Bradley and John Montecucco made a ski descent of the rarely climbed Wickersham Wall. They dropped down from Kahiltna Pass to the Peters Glacier. They climbed the Canadian route on the Wickersham Wall. They had a unique approach by ferrying loads up to each higher camp, skiing back down to their camp and then moving up the next day, in effect skiing the route bottom to top. On May 24, they skied the final section from the north summit. They descended the West Buttress route.
