Avalanche Summary
No recent avalanche activity has been reported.

Snowpack Summary
Up to 25 cm of low-density snow has fallen since the weekend. A thick, supportive melt-freeze crust is buried by 30 to 60 cm and is present up to roughly 2000 m elevation. Below the crust, the mid-snowpack is generally well consolidated with no layers of concern. A weak layer of facets and a crust buried in November is down 70 to 150 cm from the surface. The lower snowpack below this November weak layer is weak and unconsolidated.
Treeline snow depths are roughly 150 to 200 cm.

Terrain and Travel Advice
- Uncertainty is best managed through conservative terrain choices at this time.
- Closely monitor how the new snow is bonding to the old surface.
- Avoid steep, rocky, and wind effected areas where triggering slabs is more likely.
Problems
Deep Persistent Slabs
Human triggering of deep weak layers remains possible in terrain with shallow, variable snowpacks. At lower elevations a supportive melt-freeze crust is providing a bridging effect, making it more difficult to trigger deeper layers.
Aspects: All aspects.
