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

Snowpack Summary

Another 5 to 10 cm of snow is expected to fall with strong wind on Thursday. Potentially building storm slabs in lee areas.

Around 30 to 60 cm of snow may overlie 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.
