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.
Snowing. Calm winds at this location, moderate SW ridge just at ridgetop.
