Regions

Pine Pass.

New snow and wind are developing windslabs in lee features.

Please consider sharing your observations to the Mountain Information Network.

Confidence

Moderate

Avalanche Summary

No avalanches have been reported in the region since Sunday.

Please consider submitting a Mountain Information Network report if you head out. Even a photo of the mountains or an idea on the surface conditions helps!

Snowpack Summary

15 to 30 cm of snow overlies a hard melt-freeze crust. This snow is likely wind-affected on exposed slopes at treeline and alpine elevations. The crust is on the surface at lower treeline and below treeline elevations

The mid and lower snowpack is well bonded with no concerns currently.

Data is very limited in this region.

Terrain and Travel Advice

  • Expect slab conditions to change drastically as you move into wind-exposed terrain.
  • Avoid freshly wind-loaded features, especially near ridge crests, rollovers, and in steep terrain.

Problems

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
