130m, 3 pitches.
P1: Straight up and into the narrow steep ice groove to gain a chimney. Follow this for 25 meters to belay on a large block (60m).
P2: Up the ramp right to a gap at 10m, then back left across a snow ramp, round a corner to belay at the foot of a narrow groove in the buttress (40m).
P3 (variation, IV/5): take the groove in the buttress to gain a pedestal. Step up right, then move left beneath a vertical 1.5m block. Surmount this to easier ground and an icy v groove which will take you to the top (30m).
