Approach info:
Hike up, like you're headed to the Petit Grepon, then hang a hard left. You can ski up from Sky Pond, if snow conditions are firm, or head west from Sky Pond, up the gully, then climb a narrow chute with a 30' ice bulge then continue onto and across the huge snowfield angling left to gain the same snow bowl below the face. the obvious weekness is a 500' feet left of the direct buttress base area.
Protection
Standard single alpine rock rack. Maybe 2-4 stubby screws, 2 KB.
We know of at least one other party that climbed the direct line through the headwall long before we did. Likely it has been done many times. Great route, likely much better in May than when we did it in April. We had a lot of sugar snow; it would be much more fun (and safer) with firmer snow. —Dougald and Greg.
