48m, 2 pitches.
Loose and serious but memorable. Climbs the crack system on the front of the buttress and the 'alpine' ridge above. Large and medium cams useful.
1) 4b, 27m. Climb the crack to a narrow ledge then the left edge to a smoother face above to the 'forepeak'. Continue to the large tottering pinnacle and belay.
2) 21m. Carefully traverse the spiky ridge and go up a slab to the top. Belays are well back in blocks.
