Kernpunkte

Where the snow is deeper, travel is easier and also where wind slabs are likely to linger. Assess steep slopes for dense or stiff snow before committing.

    Stubborn wind slabs may still be human-triggered, particularly in isolated areas where they sit directly above a weak, sugary facet layer that can be found near the base of the snowpack.

Avalanche Summary

No recent avalanches have been reported.

Snowpack Summary

Total snowpack depths are roughly 60 to 80 cm, tapering quickly at lower elevations.

The upper snowpack is variable, with wind-affected surface snow in open terrain and softer snow in sheltered areas. This overlies a crust that formed in early November. The lower snowpack consists of multiple crusts, and in some areas a layer of weak, sugary facets can be found near the ground.

In many areas, especially below treeline, there is not enough snow to smooth out surface roughness or reach the threshold needed for avalanches.In many areas, especially below treeline, there is not enough snow to smooth out surface roughness and be above the threshold for avalanches.

Terrain and Travel Advice

  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
  • Carefully evaluate steep lines for wind slabs.
  • Be cautious of buried obstacles, especially below treeline.
