Avalanche Summary
No recent avalanche activity has been reported in the region.

Snowpack Summary
The upper snowpack continues to settle and stabilize. A widespread melt-freeze crust is buried by roughly 50 to 90 cm. The crust ranges in thickness from 1 cm at higher elevations to 20 cm thick at lower elevations. The mid-snowpack is generally well consolidated below the crust. A weak layer of large facets and a crust persists down 70 to 150 cm from the surface. The snow below the crust is generally weak and unconsolidated.
Treeline snow depths are roughly 150 to 200 cm.

Terrain and Travel Advice
- Avoid steep, rocky, and wind effected areas where triggering slabs is more likely.
- The more the snowpack warms-up and weakens, the more conservative you`ll want to be with your terrain selection.
Problems
Deep Persistent Slabs
Triggering of deep weak layers remains possible in terrain with shallow, variable snowpacks. Where supportive to riders, a melt-freeze crust may be providing a bridging effect, making it more difficult to trigger deeper layers.
Aspects: All aspects.
