Avalanche Summary
No new avalanches have been reported but information is limited.
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.
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.
