Third skier down slope triggered a wind slab avalanche that caught and carried the skier before they were able to self-arrest on the bed surface. Two people, from a separate party, ascending from below were caught in the debris and partially buried.
Type: Soft slab (this was a wind slab avalanche that triggered a soft slab pocket lower on slope)
Angle: 37-43 degrees
Size estimate: 200′ wide, running 1,100′ x 8-14″ deep
Trigger: Skier unintentional (many tracks on slope)
Weak Layer: Near surface facets and decomposing particles over a crust
Debris: ~5-12′ deep
