Snowpack

Lots of action on typically windward slopes above treeline. These slopes probably had a very shallow and weak structure, some with thin crusts, prior to this storm. The lack of windscouring accompanying this significant snowfall event looks to have built dangerous persistent slab structures on these aspects now.

Avalanche

Got views this evening of 6 slab avalanches on NW, W, and SW aspects above treeline on Whiterock and Cement Mountain. D2's to D2.5's. Presumably failed 2/1. Two of them had impressively wide propagation, estimated 1,500 feet wide. These windward paths are infrequent flyers of this size.
