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

Layer/Depth:
35cm from ground

Likelihood of Triggering
Sensitivity:
Touchy

Spatial Distribution:
Widespread
Where did you find this problem?
  Primary Concern Comments: Not confidence inspiring.
STABILITY TESTS
 Stability Test Results: ECTP 8
SNOW STABILITY
 Snow Stability Rating for your observed area: Poor Confidence: MODERATE Trend: Steady
 Comments (aspects and elevations of instability, etc): This was the first tour in weeks that I have not noticed widespread cracking and collapsing. However, the weak layer and snow stability tests still indicate a dangerous avalanche problem. We stayed off of steep slopes and enjoyed the low angle pow.
BOTTOM LINE
 Comments: The front page of my avy field book has a Doug Chabot quote: "If it propagates, do not ski the slope." I am planning to continue staying off of steeper terrain until our avy conditions improve.
