Avalanche Summary
We haven't received reports of avalanche observations since Monday, when thin wind slabs were triggered by riders.
Please continue to share any observations or photos on the Mountain Information Network.
Snowpack Summary
A dusting of snow overlies a melt-freeze crust up to 2100 m. Wind-affected snow prevails above 2100 m, with thin, old wind slabs in lee terrain features from recent southwest wind.
The mid-pack continues to settle and consolidate. Facets exist near the base of the snowpack.

Terrain and Travel Advice
- When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
- Small avalanches can have serious consequences in extreme terrain. Carefully evaluate your line for wind slab hazard before you commit to it.
