    Probabilidad
    Unlikely - Possible
    Tamaño

    A deeply buried facet/crust weakness exists near the base of the snowpack. This layer could be triggered by large loads such as a cornice collapse or from a thin-spot trigger point.

Confidence

Poor - Due to limited field observations

Snowpack Summary

Up to 25 cm of recent snow is sitting over a weak, faceted old snow surface. Loose dry sluffing is likely in steep terrain sheltered from the wind. In wind-affected areas, wind slabs have formed behind terrain breaks such as ridges and ribs. A strong mid-pack overlies a weak base layer of facets and the remnants of a crust. New surface hoar growth at the surface may develop into a weak layer once buried with further snowfall.
