Avalanche Summary
No recent avalanches have been reported in the region. However, the November weak layer remains active in snowpack testing, producing spooky results.
Please continue to share any observations or photos on the Mountain Information Network.
Snowpack Summary
The upper 30 to 50 cm of generally low-density snow is settling with mild temperatures. This sits over a generally weak and faceted mid and lower snowpack. A layer buried in November consisting of facets, surface hoar, and/or a crust is near the base of the snowpack.
Treeline snow depths are roughly 140 to 160 cm.

Terrain and Travel Advice
- Avoid steep, rocky, and wind effected areas where triggering slabs is more likely.
- Don't let the desire for deep powder pull you into high consequence terrain.
Problems
Deep Persistent Slabs
A weak layer near the base of the snowpack remains a concern despite lack of recent avalanche activity. Human triggering of this layer remains possible, especially in shallow areas with variable snow depths.
Aspects: All aspects.
