West Ridge

From Colin Todd Hut cross the Iso and Dipso Glaciers at about the same height as the hut and follow a steep snow lead up to a level section on the West Ridge, about 300 metres below the summit. The steep rock ridge is then followed, with the more difficult moves occurring on its lower sections. Near the top, the ridge peters out and it may be necessary to move out on to the face to the south to gain the summit ridge, six to seven hours out from the hut.
