With all the icy surfaces at higher elevations, it is best to limit your travel and stay below the tree line to take advantage of the best snow

Snowpack Summary
At higher elevations, much of the surface was eroded to the January 18th crust by the strong westerly winds of last weekend. The 5 to 10 cm of snow received today was blown by the southeast wind and cross loaded accumulations were observed. Below the treeline, 40 to 50 cm of less wind-affected snow was found on top of the decaying January 18th crust.
In general, snowpack heights range from 70-90 cm in the valley to 100-150 cm in the mid-mountains.

Terrain and Travel Advice
- Closely monitor how the new snow is bonding to the crust.
Problems
Wind Slabs
The 5 to 10 cm of snow and moderate to strong northwest winds tonight and Saturday could form new wind slabs. Since many surfaces are icy, they may not have very good traction.
Aspects: North, North East, East, South East, South, South West.
Elevations: Alpine, Treeline.
Likelihood
Expected Size
Persistent Slabs
A layer with slab properties overlies a layer of facets over the January 18th crust. The likelihood of triggering an avalanche on this interface is unlikely, but the consequence of an event on this layer would be a large avalanche. Keep an eye out in areas where the snowpack is thinner.
Aspects: North, North East, East, South East.
Elevations: Treeline, Below Treeline.
