The first ascent was made in 1964 from the south by members of Edmund Hillary's Schoolhouse Expedition: Lynn Crawford, Pete Farrell, John McKinnon and Richard Stewart. Below the basin on the southwest face, they reached the south ridge after climbing a difficult couloir. The team described the climb as difficult and the route has never again been repeated in its entirety.[2] In 2014, Russian climbers Alexander Gukov and Alexey Lonchinskiy made the first ascent on the southwest face.[2]
