Avalanche Summary

No new avalanches have been reported since before last weekend.

Looking forward, lingering pockets of wind slab at upper elevations will be the main concern.

Please consider submitting your observations to the Mountain Information Network.

Snowpack Summary

Up to 25 cm of snow overlies a crust from rain last week. Strong wind will have scoured windward slopes and redistributed dry snow into small wind slabs.

The remainder of the snowpack is strong, with various hard layers and crusts.

Terrain and Travel Advice

  • Be careful as you transition into wind-affected terrain.
  • Keep in mind a buried crust offers an excellent bed surface for avalanches.
  • A hard crust on the snow surface will help strengthen the snowpack, but may cause tough travel conditions.
