Snowpack Summary
At higher elevations, much of the surface was eroded to the January 18th crust by the blizzard of a week ago. The 20 to 25 cm of light snow over the last week was blown by southeast and then northwest winds. Below treeline, 50 to 60 cm of snow was found on top of the decaying January 18 crust, less affected by the wind.
In general, snowpack heights ranged from 70-90 cm in the valley to 100-150 cm in the mid-mountain.

Terrain and Travel Advice
- Recent wind has varied in direction so watch for wind slabs on all aspects.
Problems
Wind Slabs
The moderate to strong northwest wind has transported the snow of the past few days and contributed to the increase in size of the new wind slabs. Since many of the surfaces were previously icy, the bonding on them may not be very good.
Aspects: North, North East, East, South East, South, South West.
Elevations: Alpine.
