Avalanche Problems

Persistent Slabs

A surface hoar layer is buried down 50-110cm. Riders can trigger this layer from shallow snow pack areas with large consequences. Caution in areas at higher elevations that are planar and which have not previously slid.

Dig down to find and test weak layers before committing to a line.Avoid convexities or areas with a thin or variable snowpack.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 2 - 3
