Avalanche Problems

Deep Persistent Slabs

Avalanche control produced several large ground releases on Friday. Wind action will continue to provide the potential to overload this layer naturally. A skier triggering this layer would result in a large avalanche.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible - Likely

Expected Size: 2 - 3

Wind Slabs

This layer continues to settle and is becoming less of a concern. Steep cross loaded or lee slopes are likely trigger zones. Alpine snowpack depth remains highly variable. At tree line travel is good and the snowpack supportive.

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

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 3
