Avalanche Summary

Snowpack Summary
Snow surface and upper snowpack conditions are quite variable but the common theme is that most areas are hard with very little ski penetration. The snow surface may consist of any of the following: (1) faceting snow (generally widespread due to current cold temperatures) (2) hard wind scoured and pitted surfaces at higher elevations (3) a thin wind crust or small isolated wind slabs on leeward or cross-loaded features(4) surface hoar in wind-sheltered areas (5) Thin melt-freeze crust(6) late-January crust down around 10cm is breaking down with facetingThe mid and lower snowpack are well settled and there are currently no layers of concern. However, in thinner snowpack areas, a weak basal layer of facets or depth hoar may still be a concern.
