Lo esencial

With little snow, deeper snowpack areas offer the easiest travel but are also where wind slabs may linger.

Assess steep slopes for dense or stiff snow before committing.

    Stubborn wind slabs may still be human-triggered, likely terrain features are directly lee of ridges at upper elevations and behind ribs, gullies, and other terrain breaks.

Avalanche Summary

No new avalanches 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.

Terrain and Travel Advice

  • Carefully evaluate steep lines for wind slabs.
  • Watch for areas of hard wind slab on alpine features.
  • Avoid steep, rocky, and wind-affected areas where triggering slabs is more likely.
