Avalanche Characteristics
Character/Avalanche Problem:
Wind Slab

Layer/Depth:


Likelihood of Triggering
Sensitivity:
Unreactive

Spatial Distribution:
Isolated
Terrain
  Problem 2 Comments: Primarily a problem on steep, upper elevation slopes, but with the way the winds been blowing its possible to find isolated slabs at middle elevations as well.
STABILITY TESTS
 Stability Test Results: ECTP22 down 80cm (twice) at 1219 interface on N aspect at 7,900'.
