Avalanche Problems

Deep Persistent Slabs

The weak Oct.26 facets and depth hoar at the base of the snowpack have a significant slab (50-130cm thick) sitting above them. The likelihood of triggering this layer has decreased, but may still be found in extreme terrain.

Avoid thin, rocky or unsupported slopes.

Aspects: All aspects.
