Avalanche Summary

Small loose wet avalanches and sluffing within recent snow were observed on Thursday.

Please consider submitting your observations to the MIN if you head to the backcountry.

Snowpack Summary

5 to 20 cm of recent snow sits on a hard melt-freeze crust except for shady high alpine slopes, where it sits on faceted snow over a hard crust. Thicker deposits may exist in lee terrain features near mountain tops. The snow surface on sun-exposed slopes may moisten if sunny skies prevail and freeze into a crust overnight.

A layer of weak faceted grains above a hard crust that formed in early February is buried about 50 to 110 cm deep. This layer is currently dormant.
