Curtain Route (Standard Route)

From Harper Saddle ascend the snowslope diagonally to the gap in the west ridge (beware rockfall from the Curtain). Continue up the ridge for 150m before crossing left to a major couloir. Ascend the couloir which comes out about 100m down the ridge from the final 40m rock wall below the summit. Descending: Five abseils (bolt anchors) from the top of the couloir followed by an easy traverse across a rock ridge onto the slopes below the Curtain allows easy access to Harper Saddle. Do not rappel down the Curtain.
