English

Subject field(s)
  • Atmospheric, Climatic and Meteorological Phenomena
DEF

The surface on which an avalanche slides.

CONT

Slab avalanches are most often the greatest threat to backcountry travelers. There are two main components in the snowpack that need to be present for these to occur: a cohesive slab layer and a sliding layer underneath the slab (called the bed surface) which is characterized by poor layer bonding and low shear strength ...

CONT

Slab avalanches fall when a well-defined snow later breaks free and slides away. The sliding surface is usually the interface between distinguishable layers of snow which has been formed by variations in weather or snow deposition. In some cases the sliding surface may be the ground (entire snow cover avalanches).

CONT

The bed surface can be the ground (or older snow).

CONT

The bed surface of that avalanche was facetted grains. [Example approved by the Avalanche Bulletin Terminology Standardization Committee.]

OBS

Not to be confused with "failure layer" or "failure plane."
