Comments

Observed what appears to be a skier triggered avalanche on a wind loaded slope at top of Decker Lake Run Left. Tracks drop in near cornice at top of small ridge feature. Slide propagated underneath the entire length of the cornice and track exits right side of slide. Was not present for incident so some uncertainty as to actual events. Wind loaded storm slab failed on weak layer 50-100cm down.
