Avalanche Summary

No recent avalanche activity has been reported.

Observations remain limited this early in the season. If you head into the backcountry, please post to the Mountain Information Network

Snowpack Summary

Small amounts of new snow are expected to accumulate across the region, burying a mix of surfaces. In exposed, wind-affected terrain, the new snow will cover firm, wind-affected surfaces. In wind-sheltered areas, it may bury small surface hoar or faceted crystals.

A crust buried in early November exists about roughly 50 to 90 cm down from the surface. Reports suggest that weak faceted crystals or surface hoar may exist above the crust in some areas.

Various melt-freeze crusts can be found at the base of the snowpack, which are not concerning avalanche layers at the moment.

Snow depths at treeline are roughly 80 to 150 cm, and decrease rapidly at lower elevations.

Terrain and Travel Advice

  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
  • Watch for signs of slab formation throughout the day.
  • Seek out sheltered terrain where new snow hasn't been affected by wind.
  • Be cautious of buried obstacles, especially below treeline.
