Avalanche Problems

Wind Slabs

Aspects: North, North East, East.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 3

Loose Dry

Loose snow avalanches involving last week's storm snow are possible in steep alpine and treeline terrain. Surface hoar buried in 35cm of storm snow may be easily triggered by skiers producing fast moving sluffs in steep treeline to alpine areas.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 2
