North Rockies

As wind speeds increase throughout the day, wind slabs will become an increasing concern, especially at higher elevations.

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

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.

• Be especially cautious as you transition into wind-affected terrain.
• Seek out sheltered terrain where new snow hasn't been affected by wind.
• Make observations and continually assess conditions as you travel.
