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.

Terrain and Travel Advice

  • Avoid shallow, rocky areas where the snowpack transitions from thick to thin.
  • Make observations and assess conditions continually as you travel.
  • Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.
