Avalanche Summary

No recent avalanches have been reported.

Snowpack Summary

A thick supportive surface crust is capping the snowpack. Below the crust is the recent storm snow which is around 50-70cm deep and sits on a previously variable snow surface that included wind affected surfaces, a freezing rain crust or sun crust, and/or surface hoar or sugary facets in sheltered terrain. In the middle of the snowpack you might find the mid-December surface hoar or crust/facet weak layers. These are now typically buried 1m or more. The old surface hoar layer may be found in sheltered shady areas at and below treeline, while the slightly deeper crust/facet layer is expected to be more widespread but also more variable.
