Avalanche Summary
No recent avalanches observed.We would very much appreciate it if you spend a moment to submit any observations you have to the Mountain Information Network here, even if it is just a photo. Thanks!
Snowpack Summary
Alpine snow depths in the region are around 60 to 80 cm. 10 to 30 cm of recent storm snow overlies a layer of surface hoar that was buried on November 21. This layer is expected to be variable in nature and may have been melted into a crust on southern aspects.
Problems
Storm Slabs
Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
