Avalanche Summary

We haven't received any reports of recent avalanche activity.

Please consider posting a MIN if you head into the backcountry.

Snowpack Summary

Around 10 to 20 cm of snow accumulated since the start of the weekend. Strong southwest wind likely formed deeper and touchier slabs in lee terrain features.

Around 30 to 60 cm of snow may overly surface hoar and/or faceted grains and a hard melt-freeze crust from mid-November. Weak faceted grains may extend to the base of the snowpack, particularly in areas where the snowpack is thin.

Snow depths at treeline vary from about 50 to 100 cm and decrease rapidly at lower elevations.
