Tiphaine Duperier and Boris Langenstein from France have made first ski descents in many parts of Asia. But until 2022, Tiphaine had never been to North America. In May, she flew to Alaska with Boris to pursue a crazy dream: a ski descent of the Cassin Ridge on Denali. The two quickly realized this wouldn’t be possible (at least this year), but an alternate vision soon appeared: a ski line down the upper southwest face of Denali. On May 31, the two climbed to the summit and started down just to skier’s right of the upper Cassin. After descending about 1,000 meters, they made a long, terrifying traverse to join the West Rib route and continued down all the way to the Northeast Fork of the Kahiltna Glacier. The total descent was more than 3,800 meters. For this episode of the Cutting Edge, Tiphaine spoke with guest interviewer Brody Leven, a professional ski mountaineer himself, about the planning and execution of this bold descent.
