Avalanche Details

Planned to ski one of the further back chutes. Based on the thinner snow pack and wind scoring of the ridge line we opted for a lower entry into chute. On my initial ski cut a wind slab released. It propagated down and across for roughly 50 feet sliding down toward the drainage. The depth of snow was 8"-12" very fast moving, pulled out to the ground. Mostly light. Wind affected snow slid.
I skied to an island of safety and watched the snow spill into the valley floor. We then opted to retreat back down the ridge and ski a mellow open glade back to the car.
