Problems

Wind Slabs

Facetting is helping ease this problem at treeline. The alpine on the other hand is still covered in windslabs of varying densities.

Use caution in lee areas. Recent wind loading has created wind slabs.Evaluate unsupported slopes critically.

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

Elevations: Alpine, Treeline.

Likelihood

Unlikely - Possible

Expected Size

1 - 2.5

Deep Persistent Slabs

Large triggers are a concern. It's safe to say we're in the "low probability/high consequence" situation. Avoid thin areas.

Be aware of the potential for full depth avalanches due to deeply buried weak layers.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood

Unlikely - Possible

Expected Size

2 - 3.5
