Old wind slabs may remain be surprisingly reactive where they sit over weak grains and a crust.

Moderate
Avalanche Summary
No avalanches have been observed recently.
Snowpack Summary
A dusting of new snow may sit over heavily wind-affected surfaces in the alpine and at treeline. Pockets of soft snow can be found in sheltered, lower angle terrain.
A crust from early December is buried 30 to 50 cm deep. A weak layer of surface hoar or facets may be found above it. This layer is likely to persist as an avalanche problem as it gets buried deeper.
The remainder of the snowpack is well settled and bonded.

Terrain and Travel Advice
- The best and safest riding will be on slopes that have soft snow without any slab properties.
- Be especially cautious as you transition into wind-affected terrain.
- Avoid steep, rocky, and wind-affected areas where triggering slabs is more likely.
Problems
Wind Slabs
Old, hard wind slabs sitting on faceted snow in shallow, rocky start zones may remain reactive to a human or machine triggers.
