    Where winds have impacted surfaces, particularly around ridgelines, thin wind slabs are found and may be reactive to human traffic. Winds have switched directions creating wind slabs on a variety of aspects.

Avalanche Summary

Reports on Saturday indicate avalanche activity was limited to a few wind slabs to size 1.5 at treeline and some loose dry avalanches from steep terrain to size 1.

Please continue to post your reports and photos to the Mountain Information Network.

Snowpack Summary

10-20 cm of new snow from the weekend is found in wind-sheltered terrain features. In some areas, new snow sits on top of a thin melt-freeze crust. 50 cm of settling snow sits over a hard crust at higher elevations. Below 700 m surface is a hard crust.

Last week's rain saturated the snowpack and created a well-consolidated lower snowpack.
