Use extra caution on steep slopes near ridgecrest where fresh wind slabs are more likely to be found. Increase your exposure to avalanche terrain gradually as you gather information moving throughout the terrain.

Avalanche Summary
On Wednesday, several natural wet loose avalanches were reported to size 1.5 on steep solar aspects.
On Tuesday, a size 1 skier remote wind slab avalanche was reported in the Whistler area at 1650 m on a north aspect. The bed surface of the avalanche was a crust down 30 cm. Check out the great MIN report for details.
Please continue to share any observations or photos on the Mountain Information Network.
Snowpack Summary
A melt-freeze crust covers 20-40 cm of settling snow on solar slopes in the alpine. On sheltered polar slopes in the alpine, snow surface is preserved.
A thick crust from mid-January is 40-70 cm found deep. Weak layers exist within the mid and lower snowpack but the thick crusts sitting above them make triggering avalanches on these layers unlikely.

Terrain and Travel Advice
- Carefully evaluate steep lines for wind slabs.
- A crust on the surface will help bind the snow together, but may make for tough travel conditions.
- Use ridges or ribs to avoid areas of wind loaded snow.
Problems
Wind Slabs
Watch for wind slabs on isolated features at higher elevations. Strong northwest winds may transport new snow and preserved snow into small pockets in lees.
