Avalanche Canada
Keep backcountry travel low-risk and close to the car. With really cold temperatures and some of the shortest daylight hours of the year, any sort of incident (even broken equipment) could quickly become an epic.

Avalanche Summary
No new avalanches have been reported in the past few days in the region.
Please continue to share any observations of photos on the Mountain Information Network!
Snowpack Summary
40-80 cm of snow continues to bond and settle over a generally weak sugary, facetted mid and lower snowpack. Isolated pockets of wind slab persist in wind-exposed terrain at higher elevations.
Snowpack depths are highly variable, ranging from 80-180 cm in the alpine. Below treeline the snowpack is thin and sugary making it a challenge to access terrain in many areas without damaging your sled or skis.

Terrain and Travel Advice
- Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
- Seek out sheltered terrain where new snow hasn't been wind-affected.
- Early season avalanches at any elevation have the potential to be particularly dangerous due to obstacles that are exposed or just below the surface.
- Recent wind has varied in direction so watch for wind slabs on all aspects.
Problems
Wind Slabs
Cold arctic air and northeasterly wind will build fresh slabs on lee features. Watch for pockets of cohesive snow in exposed terrain at upper elevations, around ridges and convex rolls.
Aspects: All aspects.
