Avalanche Summary
No new avalanches have been reported. However, observations have been minimal throughout the early winter.

Snowpack Summary
5 to 15 cm of recent snow may have buried a layer of surface hoar that sits atop a widespread crust. The crust may be supportive at lower elevations, while it becomes thinner and breakable around treeline elevations. In the alpine, this crust appears not to exist, where roughly 20 to 30 cm of recent snow sits on various layers of crusts and facets.
Overall, the snow depth remains relatively shallow, creating challenging travel conditions and numerous hazards present at or just below the snow surface across all elevations.

Terrain and Travel Advice
- Avoid areas where the snow feels stiff and/or slabby.
- Keep in mind the crust offers an excellent bed surface for avalanches.
- Early season avalanches at any elevation have the potential to be particularly dangerous due to obstacles that are exposed or just below the surface.
Problems
Wind Slabs
Expect to find pockets of freshly formed surface slabs. New snow may be sitting on a layer of surface hoar and/or a crust.
