Avalanche Problems
Persistent Slabs
Steep open slopes at and above treeline have a soft to hard wind slab that is sensitive to human triggering and is failing near the ground on the basal depth hoar. In some places, this layer is failing on a surface hoar layer and then stepping down.
Aspects: North, North East, East, South East, South.
Elevations: Alpine, Treeline.
Likelihood: Likely
Expected Size: 1 - 3
