PROFESSIONAL OBSERVATION FORM
 Start Date: 03.31.19 Name: Savage - OFF DUTY Operation: SAC
 Drainage/Route:  Croy (Lambs and Vorberg) - OFF DUTY Observed Terrain:  5400-6600', W-S-E-NE Zone/Region:  Wood River Valley
WEATHER OBSERVATIONS
 HN24: 0 HST: 0 Sky: CLR Precip: Temps: 30s and 40s F
 Ridgeline Wind: Light and Steady from the W
 Blowing Snow: None Snow Available for Transport: None
AVALANCHE OBSERVATIONS
None Reported
SNOWPACK OBSERVATIONS
 HS: 0-120cm, mostly 50-70cm 
 Upper Pack: 2-8cm of soft/wet, well-developed, melt freeze particles everywhere we went except NE aspects at ridgeline...wind blown DF with some melt freeze on NE just below ridges...did not observe N or NW: hard supportable crust beneath surface snow on all observed aspects.  
 Middle Pack: Not observed, but poking pole to ground indicated moist and damp crystals retaining hardness in the layering (took a fair amount of force to get a pole through the snowpack).  
 Lower Pack: Not observed.  
AVALANCHE PROBLEM ASSESSMENT
Avalanche Characteristics
Character/Avalanche Problem:
Wet Loose

Layer/Depth:
surface

Likelihood of Triggering
Sensitivity:
Unreactive

Spatial Distribution:
Specific
Terrain
  Primary Concern Comments: Frozen crusts maintained their structure as of 4PM, but there may be minor issues on W-SW below 6500' later this afternoon.
STABILITY TESTS
 Stability Test Results: None performed
OBVIOUS SIGNS OF INSTABILITY
 Marked with checkmark if observed:
 Collapsing (isolated) Depth: 15cm Length: 50cm
 Comments: Crusts bending and collapsing near sage and grass clumps where snowpack was less than about 40cm deep.
SNOW STABILITY
 Snow Stability Rating for your observed area: Very Good Confidence: HIGH Trend:
 Comments (aspects and elevations of instability, etc): Stability on SW-W aspects may worsen late today.
BOTTOM LINE
 Comments: No signs of instability, just good corn skiing on W-S-E from 1-4PM. NE aspects near ridgeline were crusty but not an avalanche hazard. Will be a lot of icy surfaces in the South Valley if it freezes hard before it snows Monday/Tuesday. There may be some breakable crusts on shady middle elevation slopes but no faceting below them for now.
