The alpine rating is Wind Slabs.
, the treeline rating is , and the below treeline rating is Known problems includeTerrain that is sheltered from the wind will hold soft, loose snow with no slab properties. That's where you'll find the best riding and the lowest avalanche danger.

Avalanche Summary
On Friday, east of Pine Pass, natural and human triggered avalanches up to size 2 were reported in wind exposed treeline and alpine terrain. See photo below for more info and a link to the MIN report.
If you are out in the backcountry consider submitting your observations to the MIN.
Snowpack Summary
In sheltered terrain, expect to find 20 to 40 cm of settling snow. South through west wind has exposed the ground on windward slopes and formed wind slabs on lee slopes and in cross-loaded terrain.
In sheltered areas, a crust from early December is buried up to 80 cm. Snowpack tests and a lack of recent avalanches suggest that this layer has gotten stronger and is no longer a concern. However, observations are limited in this region.
The lower snowpack is settled and strong.
Data is very limited in this region, please submit MIN reports if you head into the mountains. Any information or photos are helpful!

Terrain and Travel Advice
- Expect slab conditions to change drastically as you move into wind-exposed terrain.
- Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
- Look for signs of instability: whumphing, hollow sounds, shooting cracks, and recent avalanches.
Problems
Wind Slabs
Avalanches are most likely where the wind has formed the recent snow into wind slabs on leeward slopes in cross-loaded terrain.
