PROFESSIONAL OBSERVATION FORM
 Start Date: 03.26.19 Name: Davis Operation: SAC
 Drainage/Route:  Peak 2 Observed Terrain:  5800-9200' Zone/Region:  Soldier Mountains
WEATHER OBSERVATIONS
 HN24: 0 HST: 10-20 cm Sky: VAR Precip: S-1 Temps: 36F
 Ridgeline Wind: Light and Intermittent from the Variable
 Blowing Snow: Prev Snow Available for Transport: Small amounts
 Comments: Mostly cloudy with some periods of more intense filtered sun and short stints of blue. Pretty much calm while I was up high.
AVALANCHE OBSERVATIONS
 No. Location Date Size Type Trigger Aspect Elevation Comments
 Few Peak 2 and Smoky Dome Within past week 1 N >9,000 There were some D1 sized piles in Big Bowl on Peak 2 and along the Soldier Crest toward Smoky Dome.
SNOWPACK OBSERVATIONS
 HS:  
 Upper Pack: 4-8" settled HST between 7000 and 9200'. The sun/warm temps yesterday had formed a soft MFcr on the surface up to about 8000'.  
 Middle Pack:  
 Lower Pack:  
AVALANCHE PROBLEM ASSESSMENT
Avalanche Characteristics
Character/Avalanche Problem:
Wind Slab

Layer/Depth:
20-40 cm

Likelihood of Triggering
Sensitivity:
Stubborn

Spatial Distribution:
Specific
Terrain
  Primary Concern Comments: The MFcr up to 8000' hampered any additional wind slab formation at middle elevation last night. The snow at upper elevation had been worked over already and the slabs I encountered were well bonded.
STABILITY TESTS
 Stability Test Results:
SNOW STABILITY
 Snow Stability Rating for your observed area: Good Confidence: MODERATE Trend: Improving
 Comments (aspects and elevations of instability, etc): Likely the low end of MOD at upper and LOW below.
BOTTOM LINE
 Comments: Although the Soldiers have received more snow and wind, the wind slabs that formed with the snowfall beginning Sunday seem to have bonded well, aided by warm temps. There was some sign of D1 activity that likely occurred during the loading, but it was isolated to upper elevation ridge lines. Another day of warm temps today should put a cap on any remaining snow available for transport barring a strong N wind event.
