140m. Based on the summer line. Protection is limited, but there is some on the hard sections. Climb the lower crest to a terrace at half-height. Continue more steeply up the crest to a corner on the left (belay), from where a grass ledge leads left. Follow this to its end, then make an axe traverse left across a diminishing slab to gain a steep groove which is followed to easier ground and the summit of the buttress.
