Avalanche Problems

Wind Slabs

Variable wind slabs exist throughout the landscape.
Be careful with wind loaded pockets. Be aware of wide variation in snowpack depthBe careful with wind loaded pockets while approaching and climbing ice routes.

Aspects: North, North East, East, South East.

Elevations: Alpine, Treeline.

Likelihood: Unlikely - Possible

Expected Size: 1 - 2

Persistent Slabs

Observations are very limited leading to uncertainty for the potential to trigger this layer.
Carefully evaluate big terrain features by digging and testing on adjacent, safe slopes.Cold temperatures have stabilized the snowpack, but watch out for frostbite.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Unlikely - Possible

Expected Size: 1 - 3
