Avalanche Summary

No new avalanches have been reported. Looking forward, snow and wind forecast for the next few days will likely promote a new round of storm slab activity.

Snowpack Summary

A light dusting of snow covers a medley of surfaces which include stubborn wind slabs and wind-scoured exposed crust in the alpine, and soft unconsolidated snow in sheltered areas at treeline and below. About 15-30 cm below the surface you'll likely find the December 18th melt-freeze crust, which has been unreactive in recent snowpack tests. That said, I'd keep an eye on this crust as new snow accumulates overtop. Below this, the snowpack is thought to be strong and well settled. Snowpack depths are about 135 cm at the 1100 m elevation with many early season hazards present at lower elevations.
