Snowpack Summary
Cold temps are facetting the upper snowpack. Previous strong N'ly winds have redistributed last weekend's storm snow- watch for reverse loading. The main layer to watch (Nov 23rd surface hoar/ crust) is buried 25-45cm. This layer exists as a crust on all aspects below 1600m and on steep solar aspects into the alpine; surface hoar around treeline.
Avalanche Summary
No new avalanches reported from the highway or the backcountry in the last 4 days.
Confidence
Problems
Persistent Slabs
Last weekend's storm snow buried a weak surface hoar layer at treeline and below, and a crust on steep solar aspects into the alpine. Cold temps appear to have decreased slab properties in the upper snowpack, but this layer should not be discounted.
- Dig down to find and test weak layers before committing to a line.
Aspects: All aspects.
