Avalanche Summary

Several size one storm slab and dry loose avalanches were reported on Sunday. These avalanches ran on a layer of facets and surface hoar just beneath the new snow.

Snowpack Summary

3-5 cm of new snow now overlies a previously heavily wind effected surface. Faceting of the upper snowpack is widespread, and surface hoar up to 8 mm has been buried beneath the new snow at the treeline and below.

Two layers of surface hoar exist between 40 cm and 60 cm beneath the snow surface, there hasn't been much avalanche activity on these layers.

A layer of facets on top of a crust from early December is buried 100 to 200 cm deep. This layer is generally not a concern in this region.
