Climbs the sharp edge of the left arete. Stand start and climb on good holds until about the 15 foot mark, where you'll find a large edge around the corner. Chalk up here as this is the last good hold before the crux. Tippie-toe and reach for for a flat edge, then another one above that (slightly worse). Bring your right foot up to a long crimp, and do one more committing move to a better edge that you have to trust is there. Jugs after this to top out.
An enormous undertaking for its grade. Has only seen two ascents.
