AVALANCHE PROBLEM ASSESSMENT
Avalanche Characteristics
Character/Avalanche Problem:
Wind Slab

Layer/Depth:


Likelihood of Triggering
Sensitivity:
Unreactive

Spatial Distribution:

Terrain
  Primary Concern Comments: 
 Comments: Wind slabs at upper elevation were the primary concern in the terrain that I traveled through, though the wind slabs that I encountered were generally unreactive.
STABILITY TESTS
 Stability Test Results:
OBVIOUS SIGNS OF INSTABILITY
 Marked with checkmark if observed:
 Cracking (isolated)    
 Comments: Very isolated cracking where fresh slabs sat on steep, planar, icy surfaces.
SNOW STABILITY
 Snow Stability Rating for your observed area: Confidence: Trend:
 Comments (aspects and elevations of instability, etc): Low seemed appropriate for the terrain that I was in, but I would have been hesitant to tangle with steeper slopes with widespread, stiff slabs, due to uncertainty. The lack of a thicker slab on PWLs in the upper Boulder's has helped maintain better stability in this area. That might be changing this week.
