DEF

Facets located at or near the base of the snowpack.

CONT

Large climax avalanches have been releasing on the basal facets and/or glacial ice. [Example approved by the Avalanche Bulletin Terminology Standardization Committee.]

OBS

The facetting process occurs within the snowpack and is driven by temperature patterns and vapour flow from ground to snow surface. Facets can form anywhere in the snowpack, but in certain climates basal facets are predominant. For example, in the Coast Range it is very rare to see basal facets but it is an annual occurrence in the Rocky Mountains. [Reference: Grant Statham, Avalanche specialist, Parcs Canada.]

OBS

basal facet: term officially approved by the Avalanche Bulletin Terminology Standardization Committee.
