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

Layer/Depth:
100 to 150cm

Likelihood of Triggering
Sensitivity:
Not Observed

Spatial Distribution:
Widespread
Terrain
  Primary Concern Comments: 2/2 and 2/23 interfaces. Worst on solars, but present around the compass.
 
Avalanche Characteristics
Character/Avalanche Problem:
Deep Persistent Slab

Layer/Depth:


Likelihood of Triggering
Sensitivity:

  Problem 2 Comments: Really hard to stop worrying about this.
 
Avalanche Characteristics
Character/Avalanche Problem:
Wind Slab

Layer/Depth:


Likelihood of Triggering
Sensitivity:
Unreactive

Spatial Distribution:
Specific
Terrain
  Problem 3 Comments: Bounced on a lot of wind slabs without results. They seem to have run their course, for the most part. If you could find one deposited directly on an icy, alpine surface you could maybe get something to go, but with so much fresh snow around they are mostly sitting on storm interfaces.
