Triggered small storm slab avalanche today below Mammoth Rock Bowl while ski cutting steep convexity. ~25ft wide, 8-10" crown. D1.5, R1. Soft new storm snow from today failed on old snow surface. Very soft slab. Wouldn't have resulted in burial here, but definitely could have if a terrain trap was involved, and was enough to knock someone off their feet and could have resulted in injury above consequential terrain.
