40-50 cm of unconsolidated snow or buried windslabs in exposed areas. A recently buried thin crust exists on solar aspects. The Feb 3 melt freeze crust is now down ~50cm on all aspects and elevations. This crust is up 30cm thick and has moist snow to ground below it. Snowpack depths between 50 - 200 cm.

Terrain and Travel Advice

  • Pay attention to the wind, once it starts to blow fresh sensitive wind slabs are likely to form.

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.
