Avalanche Summary
No recent avalanches have been reported, but observations are limited this time of year. If you do head into the backcountry please submit a MIN report!
Snowpack Summary
Strong wind from the east over the past week has scoured east slopes and created hard wind slabs on south and west facing slopes.
A layer from mid-November is buried 50 to 70 cm at treeline. This layer consists of surface hoar, facets and a crust below treeline and on south facing slopes. This layer was reactive a week ago (Nov 27 and 28), but has likely trended towards being unreactive under the current conditions.
Many early-season hazards exist below treeline such as rocks, stumps, and open creeks.

Terrain and Travel Advice
- Recent wind has varied in direction so watch for wind slabs on all aspects.
- Avoid steep, rocky, and wind effected areas where triggering slabs is more likely.
- Back off slopes as the surface becomes moist or wet with rising temperatures.
Problems

Lingering wind slabs are likely becoming more challenging to trigger, but they may still be found in steep unsupported terrain at treeline and above.
