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

Layer/Depth:


Likelihood of Triggering
Sensitivity:
Unreactive

Spatial Distribution:

Terrain
  Primary Concern Comments: 
 Comments: Really only worried about windslabs where they sat on PWLs, much more of a persistent slab problem than a wind slab problem. Strong wind at the tail end of the previous storm had removed much of the recent snow at upper and middle elevations, which didn't leave much behind to settle into a slab.
