Avalanche Problems

Deep Persistent Slabs

Avoid steep cross winded terrain such as old moraines or shallow gullies. Additional loading can trigger large avalanches where the snow has been stiffened by the wind. No new avalanches seen from this layer in the Bald Hills today.

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

Elevations: All elevations.

Likelihood: Possible - Likely

Expected Size: 2 - 4

Storm Slabs

Steep cross or lee winded slopes with steep convex roles are likely slab trigger zones. In the alpine the snowpack depth is highly variable. At treeline travel is good and the snowpack supportive.

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

Elevations: Alpine, Treeline.

Likelihood: Possible - Likely

Expected Size: 2 - 3
