Snowpack Summary
A skiff of snow overlies old wind slabs on higher north and east facing terrain and sun crusts on solar aspects. Wind slabs are extensive in exposed areas and cornices are reported to be well developed. A surface hoar/facet/sun crust layer from mid February (12th) may be buried in the top 20 cm or so, where it hasn't been blown away by the wind and is likely making some of the wind slabs more touchy. Mid and lower snowpack layers are generally well settled and stable.
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.
