Avalanche Problems

Deep Persistent Slabs

The strength of the bridging over the basal weakness will determine it's sensitivity to triggers. Deep penetrating cold has weakened shallow areas and may be more susceptible to triggering and propagation.

Be aware of thin areas that may propogate to deeper instabilites.
Use caution on open slopes and convex rolls
