Avalanche Problems

Wind Slabs

Possible small pockets poorly boded to older surface in steep locations.

Avoid freshly wind loaded features.

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

Elevations: Alpine.

Likelihood: Unlikely - Possible

Expected Size: 1 - 2

Deep Persistent Slabs

Weak basal facets are generally well bridged. However, at isolated shallower locations a large deep slab may be triggered.

Be aware of the potential for large, deep avalanches.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Unlikely

Expected Size: 3 - 4
