Climb to the col west of Duncan’s Knob, either from Glacier Burn or Aspiring Flat. The ridge is then followed, with some minor digressions on the north side to turn some of the early bumps. A difficult step about 70m high occurs just past a sharp bend in the ridge; beyond this the ridge is a mixture of very easy sections on loose rock and more demanding climbing on the steeper sections, until the col at the foot of the final step below the peak is reached. This step has been climbed by a difficult chimney on the north east side, but easier ledges with good holds are present on the Avalanche Glacier side.
The first ascent, from a bivvy near the col at the end of the ridge, required about nine hours to the summit.
