Avalanche Summary

A natural avalanche cycle occurred earlier in the week as rain and warm temperatures infiltrated the region.

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

Recent snowfall overlies a crust or moist snow from rain earlier in the week. Strong winds will create heavily wind-affected surfaces and redistribute dry snow into 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.
