Avalanche Summary
Recent skier triggered wind slabs have been limited to size 1. Explosive control work conducted prior to the weekend produced size 2 cornice and storm slab avalanches.
Snowpack Summary
Wind slabs on a variety of aspects are likely beginning to facet and lose cohesion in the cold temperatures. 50-100 cm of snow sits on a persistent weak layer that consists of facets at upper elevations, surface hoar in sheltered areas, a melt-freeze crust below 1900 m, and a sun crust on south-facing slopes. There could be more than 100 cm on this layer in wind loaded areas.
A crust from early December may be found around 200+ cm deep in the snowpack. Under the current conditions, it has been unreactive.
