Avalanche Summary

There are no recent reports of avalanche activity.

Snowpack Summary

There is 5-15 cm of snow accumulation from the past several days. In exposed terrain this may be sitting on old buried wind slabs in lee terrain features near ridges. Terrain sheltered from the wind has about 10-20 cm of soft snow. This snow may sit above a layer of surface hoar crystals. A weak layer of facets that formed during the arctic outbreak in December is buried 30 to 60 cm deep. Observations suggest it is fairly widespread, but not reactive to triggering under the current conditions.
