Points saillants

Seek out areas with soft powder snow on the surface.

Recent snow will be more likely to avalanche in terrain that has been affected by wind.

    Fresh snow will be easily moved by wind, watch for reactive slabs around ridgecrest and steep tools. Alpine-like features at treeline that are cross-loaded will be a concern.

Avalanche Summary

On Thursday through Saturday, several small explosive and rider-triggered avalanches were reported in the recent snow in alpine and treeline terrain.

Snowpack Summary

Alpine terrain is wind-affected, while sheltered areas have settling snow from recent storms.

A layer of facets, surface hoar, and/or crusts buried in early December is 50-70 cm deep. No avalanches have been reported on this layer since December 19 and it's possible that the recent mild temperatures helped it bond to the rest of the snowpack.

The lower snowpack is strong and settled south of Highway 1, and potentially weaker and more faceted north of Highway 1.

Treeline snow depths vary from 90-150 cm.

Terrain and Travel Advice

  • Make observations and continually assess conditions as you travel.
  • Be alert to conditions that change with elevation, aspect, and exposure to wind.
  • Watch for signs of instability like whumpfing, hollow sounds, shooting cracks, or recent avalanches.
