Avalanche Summary

No new avalanche reports since the weekend.

Snowpack Summary

Wind-affected snow sits on variable interfaces, including surface hoar in sheltered areas and sun crusts on solar aspects. These interfaces may be deeper on wind-loaded slopes.

A previous weak layer from early December (surface hoar or facet/crust combo) is found 50 to 120 cm deep, but snowpack tests and lack of recent activity suggest it's no longer a concern.

The lower snowpack is generally strong and bonded.

Terrain and Travel Advice

  • This is a good time for exploring terrain.
  • Carefully evaluate steep lines for wind slabs.

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.
