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

Layer/Depth:
30-40cm down

Likelihood of Triggering
Sensitivity:
Touchy

Spatial Distribution:
Specific
Terrain
  Primary Concern Comments: 
STABILITY TESTS
 Stability Test Results: LOC down 30-40 on NW, N aspects above 9000. ECTP5. will send video.
OBVIOUS SIGNS OF INSTABILITY
 Marked with checkmark if observed:
 Cracking (widespread)   Length: 100-150cm
 Collapsing (widespread) Depth: 30-40 Length: 5-10m
 Comments: frequent and widespread hard indicators of instability wherever we expected previous underlying snow. No activity on E, SE.
SNOW STABILITY
 Snow Stability Rating for your observed area: Confidence: Trend:
 Comments (aspects and elevations of instability, etc): specific aspects and elevation, where previous underlying snow.
BOTTOM LINE
 Comments: out to get a quick feel of the early snowpack distribution and confirm suspicions of new slab instability on basal facets. Widespread indicators where suspected. Multiple hazards at or just below the snow surface. Too hazardous to ski steeper terrain where pre-existing snow, basal facets give "upside down" feel to even the most cautious low angle wiggling.
