Skiers in the northern Bridgers noticed this natural slab avalanche. From an email: "Extremely weak, faceted snowpack on w-e slopes all the way up to 8000ft or so. Widespread cracking and collapsing, basically a 14in storm slab on top of total garbage. Observed a good size natural in steep, north facing terrain at about 7800ft, starting zone was a big slough fan and broke what looked like 2-3ft deep, presumably on the dry spell facets."
