PROFESSIONAL OBSERVATION FORM
 Start Date: 03.14.17 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: 0 HST: 0 Sky: SCT Precip: Temps: 38-43F
 Ridgeline Wind: Moderate and Intermittent from the W
 Blowing Snow: None Snow Available for Transport: None
 Comments: Winds light to moderate on ridgeline depending on location.
AVALANCHE OBSERVATIONS
 No. Location Date Size Type Trigger Aspect Elevation Comments
 3 N Fork Wood River(Pass Ck divide) Within past week 2 WL N S alpine S and SW, appeared to be fresh and from today (Tuesday)
 several NW Boulder Mts Today 1 WL N S alpine several new small WL in sheltered, rocky alpine terrain visible from HWY 75 (Horse Ck - Konrad Ck)
 1 Cramer Pk ridge Within past week 3 U N SE 10300 large crown, estimated 6', E/SE aspect just N/NE of summit block. See photo.
SNOWPACK OBSERVATIONS
 HS: Not observed 
 Upper Pack: Free water (melting) on all but steep, due N and NE facing slopes up to 10000'. Isolated dry, lingering wind features in true alpine terrain. Not enough melting to be a wet snow hazard on NW-N-NE, but some isolated rollerballs on sheltered shady in alpine cirques. Wet on margins though (W and E).  
 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:
Touchy

Spatial Distribution:
Specific
Terrain
  Primary Concern Comments: Touchy on W and E. Didn't get that many places to check steep, due S first hand.
 
Avalanche Characteristics
Character/Avalanche Problem:
Wind Slab

Layer/Depth:
20-100cm

Likelihood of Triggering
Sensitivity:
Not Observed

Spatial Distribution:
Isolated
Terrain
  Problem 2 Comments: Didn't stomp on much. Lots of tracks in wind features from 9600-10000', no recent small slides. Recent heat has weathered any slabs on W-S-E aspects.
STABILITY TESTS
 Stability Test Results: None performed.
SNOW STABILITY
 Snow Stability Rating for your observed area: Good Confidence: MODERATE Trend:
 Comments (aspects and elevations of instability, etc): Could have triggered WL on W and E, steep slopes (approaching 40*), getting direct sunshine and sheltered from the wind.
BOTTOM LINE
 Comments: WL problem creeping up in elevation but not a widespread problem anywhere and seemed to remain surficial in nature. Breezy W winds keeping things reasonably cool in a lot of above treeline/alpine terrain (needed to wear a shell and gloves on the ridge at times).

Large crown near Cramer, hadn't seen this noted yet. Wind loaded, likely failed at tail end of last precip event around 3-11.
