Snowpack Summary

There is about 20cm of new snow that sits on top of a generally well consolidated snowpack. Some wind effect can be found around ridges and cross loaded features. The Dec 1 crust is down about 60-70cm, below 2200m and is not a concern at this time.

Terrain and Travel

Be aware of the potential for loose avalanches in steep terrain where snow hasn't formed a slab.
Avoid freshly wind loaded features, especially near ridge crests, roll-overs and in steep terrain.

Avalanche Problems

Wind Slabs

These wind slabs are now buried and specific to lee and cross loaded features.
