Wind slabs, old snow
Avalanche prone locations
In all aspects above approximately 2200m.
Danger description
The fresh and older wind slabs are in some cases prone to triggering. The avalanche prone locations are to be found in particular adjacent to ridgelines in all aspects and in gullies and bowls, and behind abrupt changes in the terrain. Avalanches can be released by a single winter sport participant.
In isolated cases avalanches can be released in deep layers and reach medium size. This applies in particular on very steep north facing slopes in little used backcountry terrain.
Experience in the assessment of avalanche danger is required.
