Comments
This is a repeater slide for this slope. A large fetch on the windward side catches south and southwest winds. A hard wind slab with weak shallow snow underneath is the likely set-up here and the added weight of a rider who finds a thin shallow spot to collapse the slope and trigger the slide.
