Avalanche Details

On the second run of the day, the group decided to move from the standard uptrack descent towards the Southwestern/steeper aspects (skiers left). A skier triggered a windslab that extended the length of a convexity. He noted the slab and was able to ski to the side. which fortunately did not break as it was also wind-loaded.
