PROFESSIONAL OBSERVATION FORM
 Start Date: 03.11.19 Name: Davis Operation: SAC
 Drainage/Route:  Prairie/Owl Creek Observed Terrain:  7000-9475, All Zone/Region:  Smoky & Boulder Mountains
WEATHER OBSERVATIONS
 HN24: 0 HST: Sky: CLR Precip: Temps:
 Ridgeline Wind: Light and Intermittent from the S
 Blowing Snow: None Snow Available for Transport: Small amounts
 Comments: Clear blue sky. Sun had yet to moisten the surface on souths or do much to soften the crusts from yesterday by 1200. Lots of trees shedding snow.
AVALANCHE OBSERVATIONS
None Reported
 Comments: A handful of wet loose from yesterday in very steep, rocky terrain in the Boulders and headwaters of Prairie Creek.
SNOWPACK OBSERVATIONS
 HS: 140 to >240 cm 
 Upper Pack: 1-3 crusts up to 9400' on souths. Temperature or soft rain crusts on true norths below 7200'. 
 Middle Pack: Generally strong with no obvious layering during probing. 
 Lower Pack: n/o 
AVALANCHE PROBLEM ASSESSMENT

Deep Persistent Slab

Spatial Distribution:

Terrain
  Primary Concern Comments: 
 Comments: Wind slabs were soft (4F), isolated to ridgetop and produced no obvious signs of instability. There were 1-3 crusts in the upper 40 cm depending on aspect and elevation but no real slabs to speak of. I only probed for the deeper weak layers, and generally felt a stiff, strong midpack of February storm snow with no obvious interfaces. No new wet activity yet today, but I was down and out by early afternoon.
STABILITY TESTS
 Stability Test Results:
SNOW STABILITY
 Snow Stability Rating for your observed area: Good Confidence: HIGH Trend: Improving
BOTTOM LINE
 Comments: The outside chance of hitting the wrong spot and triggering a persistent/deep slab felt quite unlikely in this area. Although I was out before the heat of the day, I would have expected some additional wet loose in the afternoon.
