Avalanche Summary

Snowpack Summary

5 to 10 cm of recent snow may be covering a layer of surface hoar in sheltered areas, or a hard sun-crust on sunny slopes.

Exposed terrain in the alpine and treeline is generally wind-affected. In sheltered terrain, 10 to 40 cm of faceted snow overlies a weak layer from late January. This layer consists of a crust on sun-exposed slopes, and facets and surface hoar on all other aspects.

A weak layer of facets from early December is buried 60 to 120 cm. The base of the snowpack consists of a thick crust with facets or depth hoar in many areas.
