Avalanche Summary
No recent avalanche activity has been reported.
Snowpack Summary
Expect to find a melt-freeze crust or moist snow on the surface. The remainder of the snowpack, below the crust, is generally settled and well-bonded.
Below treeline, slopes are largely below the threshold for avalanches.

Terrain and Travel Advice
- When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
- A moist or wet snow surface, pinwheeling and natural avalanches are all indicators of a weakening snowpack.
- Carefully evaluate steep lines for wind slabs.
