Comments

Observed a large cornice failure on Mt Stanley Tuesday morning (size 2+ or a small 3) Later communication determined that it was a skier remote from a skier approaching the summit. The cornice appears to have also taken out a slab down to the basal facets on the steep NE face between the normal North Face route and the Waterman Couloir.
