Avalanche Summary
No new avalanches have been reported in the region.
If you are heading into the backcountry please consider posting your observations to the Mountain Information Network. We read every report!
Snowpack Summary
10-20 cm of recent snow sits over a thick crust capping a moist upper snowpack.
The mid snowpack contains a couple of crusts with overlying surface hoar or facet crystals which have not produced recent avalanche activity and are not a concern at this time.
The lower snowpack is well-settled and bonded.

Terrain and Travel Advice
- Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.
- Wind slabs may be poorly bonded to the underlying crust.
- A crust on the surface will help bind the snow together, but may make for tough travel conditions.
