Avalanche Details

Skier triggered a wet slab avalanche at 8:28pm in the middle of a large snow strip in the bowl of Harp Mountain, while traversing across the slope. Snow above on slightly steeper slope of same aspect was 2" penetration corn, but abruptly changed to 6+" penetration slush just before avalanche triggered. Avalanche started small and slow, but picked up speed, size and depth, and ran until the slope angle lessened by 10-15 degrees. No apparent sliding layer, bed surface was very uneven. No one was caught in the avalanche. The avalanche did not slide on the ground, there was still several feet of snow left under the bed surface.
