Snowpack Summary
Cold temperatures and strong northerly winds over the past few days have left our snow surface a variable mix of faceted snow, wind crust, and wind slab. Approximately 95 cm of well-settled storm snow lies below this surface, the product of last week's series of storms. Earlier this week, the previously mentioned strong northerly winds that followed the storms redistributed loose storm snow into wind slabs behind exposed terrain features, mainly on south to west aspects. These wind slabs have gained considerable strength in recent days and remain a concern mainly in steep, unsupported terrain. Aside from possible wind slab instabilities in the upper snowpack, the mid and lower snowpack are considered to be well settled and stable.
