Avalanche Problems

Wind Slabs

Breakable to hard slabs have formed in the alpine and open TL slopes. Watch for thin slabs on convex rolls and areas with down flow winds. Also some reverse loading has occurred from NE winds. A skier was pushed by a slide on Wed in cliff terrain.

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

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 2

Cornices

Cornices are large, and can fail unpredictably. Watch for these overhead hazards. Recent large cornice failures have not all produced slab avalanches. Hard masses of cornices have fallen as size 2.5 to 3.0 fast moving avalanches running onto fans.

Aspects: North, North East, East.

Elevations: Alpine.

Likelihood: Possible

Expected Size: 1 - 3
