Avalanche Details

Rider entered east facing slope. Around 10 turns in, rider remote triggered a large wind slab on the adjacent north facing slope. Rider moved left to safe zone upon being alerted to avalanche. Rider was not involved but some of the riders tracks were covered by the slide.

Crown was roughly 1’ deep and 300-500 feet wide. The slide quickly funneled in to the gully bellow, picked up speed and produced a large powder cloud each time it ricocheted off the snaking gully. The slide ran for 700-1000 vertical feet. All distances and sizes are estimated.
