Avalanche Summary

No new reported or observed today

Snowpack Summary

Extensive wind slabs, hard wind slabs, buried wind slabs, and sastrugi(wavy ridges of snow formed by the wind) dominate the alpine and open areas of tree line. These hard wind slabs can be tricky to evaluate because they have the potential to propagate but gives someone the impression underfoot that the base is solid. Take the time to dig and evaluate before committing to larger slopes.

Terrain and Travel

  • Watch for areas of hard wind slab on alpine features.
  • Be careful with wind slabs, especially in steep, unsupported and/or convex terrain features.

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.
