Avalanche released at feet of skier while touring below cliffs, at the top of a steep, windloaded slope. Skier was entrained and carried 150 feet downslope, buried waist-deep, but able to free themself after debris had stopped moving. Avalanche slid on old wind-sculpted surface from the major wind event. There appears to be a layer of loose, low density snow sitting on top of this old wind-sculpted surface, with denser snow from recent storms above it.
The human factor was a major contributor to this incident. Even though little was known about the snowpack, confidence was gained from watching others ski steep, windloaded faces. The skier who was caught was on high alert for shallow wind slabs, but failed to account for the possibility of slabs sliding on the deeper old/new interface.
