Points saillants

A couple centimeters of snow is welcomed, but much more is needed to make a significant difference. Skiing where there has been significant traffic previous will provide the best opportunity for good turns.

Avalanche Summary

No new avalanches have been reported or observed.

Snowpack Summary

The trace amounts of snow over the past week has added up to 10cm at treeline. This snow is overlying previous 20-40 cm thick windslabs that continue to settle and slowly strengthen with the seasonal temperatures we are experiencing. The Dec 7th temperature crust can be found on solar aspects up to 2500m down 30-50cm and the weak basal facets that once were the November and October crusts are close to ground. Thin areas where the basal layers could be triggered should be treated with caution. The windslabs seem easy to "feel" and locate as you approach ridgelines and col's and should also be treated with caution especially in convex or unsupported areas. Any avalanche in the upper snowpack will likely involve the entire snowpack and scrub down to ground so keep this in mind as you travel.
