Avalanche Summary
No recent avalanche activity has been reported.
Observations remain very limited this early in the season. If you head into the backcountry, please post to the Mountain Information Network
Snowpack Summary
Recent winds from various directions have created highly wind-affected surfaces at upper elevations, with wind slabs potentially existing on all aspects. Up to 40 cm of recent snow sits on a settled mid-snowpack in sheltered areas.
A crust formed in early November is present in the lower snowpack, with possible faceted crystals above or below it. Large depth hoar crystals exist at the base of the snowpack, particularly in the northern part of the region.
Snowpack depth at treeline is about 100 cm, and most below treeline slopes are not yet at the threshold to avalanche.
