Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 2 - 3

Aspects: All aspects.

Elevations: Alpine.

Likelihood: Likely

Expected Size: 1 - 2

Deep Persistent Slabs

These deeper layers can wake up unexpectedly. The on going storm snow may overload deep layer in some locations.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible
