If you are traveling in the mountains consider posting to the MIN.
Snowpack Summary
Previous strong wind has created variable snow surfaces in exposed terrain on all aspects and elevations. Ongoing cold temperatures have softened the upper snowpack in sheltered terrain.
A weak layer of facets and a crust from early December is buried 60 to 100 cm deep. This layer exists on all aspects up to 1750 m.
At the highway elevation, the snow is 120 cm deep, and in the alpine exceeds 200 cm.
