PROFESSIONAL OBSERVATION FORM
 Start Date: 03.29.17 Name: Savage Operation: SAC
 Drainage/Route:  Titus Ridge to Weather Station Peak Observed Terrain:  8700-10000', most aspects Zone/Region:  Smoky & Boulder Mountains
WEATHER OBSERVATIONS
 HN24: trace HST: Sky: X Precip: S-1 Temps: 30-38F
 Ridgeline Wind: Light and Intermittent from the W
 Blowing Snow: None Snow Available for Transport: Small amounts
 Comments: Cloud ceiling around 10000' plus/minus 400' for most of tour this afternoon. Winds ranged from calm to moderate, intermittent. Light snow/flurries during tour with wind moving a little snow on exposed ridges >9600'. No significant active wind loading below 10K.
AVALANCHE OBSERVATIONS
 No. Location Date Size Type Trigger Aspect Elevation Comments
 several Titus Ck headwaters Today 1 WL N NW alpine Occurred from 9000-9700' on W/NW aspects on skiers' right side of headwaters of Titus Ck, all in rocky areas and involving recent storm snow. Very small slides that couldn't bury a person, but they were notable as that's the farthest I've seen wet snow issues wrap onto the NW margin (about 315*) this spring.
SNOWPACK OBSERVATIONS
 HS: Not observed 
 Upper Pack: Wet/moist/damp on all aspects to 10000'. On solars, approaching corn with thin layer of wet crystals above crust. On shady, 5-20cm of snow with the surface getting some free water on all slopes. Saw some surface hoar up to 1cm in isolated spots (shady+sheltered) but all of it that I saw was on the surface and wet/destroyed.  
 Middle Pack: Not observed 
 Lower Pack: Not observed 
AVALANCHE PROBLEM ASSESSMENT
Avalanche Characteristics
Character/Avalanche Problem:
Loose Wet

Layer/Depth:
surficial

Likelihood of Triggering
Sensitivity:
Stubborn

Spatial Distribution:
Specific
Terrain
  Primary Concern Comments: More heat than expected today, but in general there wasn't enough snow to cause significant avalanche problems. Could have pushed snow and triggered narrow, shallow WL on very steep W/NW late this afternoon.
 
Avalanche Characteristics
Character/Avalanche Problem:
Wind Slab

Layer/Depth:
10-30cm

Likelihood of Triggering
Sensitivity:
Unreactive

Spatial Distribution:
Isolated
Terrain
  Problem 2 Comments: Wind slabs were few and far between and unreactive here.
STABILITY TESTS
 Stability Test Results: No formal tests performed.
SNOW STABILITY
 Snow Stability Rating for your observed area: Good Confidence: HIGH Trend:
 Comments (aspects and elevations of instability, etc): From about 3-6pm, it would have been possible to trigger small WL in very steep, sheltered SW-W-NW facing terrain that had more than about 4" of settled snow from the last storm. Other than that, very stable conditions.
BOTTOM LINE
 Comments: Impressive that the snow surface was moist to wet all the way to 10K on all aspects. Will be interesting to see what happenns as it snows and insulates the current surface from freezing quickly.
