Comments
HS-ACc-R5-D2.5 Stomped down a large cornice in the small hanging pockets south of the cliff at the head of the drainage. Cornice broke out pretty big at the same time as all the snow in this small pocket. No more than 30 feet across, full depth (4'-5'), maybe 45 degrees in the starting zone, extremely high energy. I would say full track for such a small terrain feature. Tree belay was helpful.
