Avalanche Problems

Persistent Slabs

Multiple weak layers in the top 1.0 m of the snowpack. These layers may become more reactive as the snowpack warms with daytime heat and weakens them. Large triggers like cornice falls may also do the trick.
Pay attention to overhead hazards like cornices.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Unlikely - Possible
