PROFESSIONAL OBSERVATION FORM
 Start Date: 03.25.17 Name: Wieland Operation: SAC
 Drainage/Route:  Miller Ridge Observed Terrain:  5600-9200 Zone/Region:  Soldier Mountains
WEATHER OBSERVATIONS
 HN24: 2-17 HST: 2-17 Sky: SCT Precip: Temps:
 Ridgeline Wind: Light from the W
 Blowing Snow: Prev Snow Available for Transport: Small amounts
 Comments: Overcast went to scattered clouds at 1200 but none in southern sky blocking sun.
AVALANCHE OBSERVATIONS
 No. Location Date Size Type Trigger Aspect Elevation Comments
 1 Lunchbox Yesterday 1.5 N E 9700
  1 Wash Canyon 1 C N E 7700 Usual runner below cornice.
 Several Buttercup NW 8500 Looked to be several possible wind slabs that ran on Buttercup but could not make out where they started.
 Comments: Intermittent clouds covering western Smokys but wasn't able to glass any slides in that area.
SNOWPACK OBSERVATIONS
 HS: n/o 
 Upper Pack: 2-3cms fresh at parking lot that was capped by thin surface crust in AM. Had broken down to 5-7cm wet grains at 1400 all aspects. 7cm HST on couch. Encountered wind affect once one Salt Bowns. Cracking 1.5' deep in drifts just above road. 2' drifts on road. HST dry on all N above 6500 , and NW/N/NE above 7000'. Other aspects moist except for in windier areas near ridges. Firm crust found below storm snow in all observed areas. 
 Middle Pack: n/o 
 Lower Pack: n/o 
AVALANCHE PROBLEM ASSESSMENT
Avalanche Characteristics
Character/Avalanche Problem:
Wind Slab

Layer/Depth:
3/24

Likelihood of Triggering
Sensitivity:
Touchy

Spatial Distribution:
Widespread
Terrain
  Primary Concern Comments: Smaller drifts along exposed mid elevation ridges. Looked to be more widespread in alpine, especially after viewing Lunchbox crown.
 
Avalanche Characteristics
Character/Avalanche Problem:
Loose Wet

Layer/Depth:
3*24

Likelihood of Triggering
Sensitivity:
Unreactive

Spatial Distribution:

Terrain
  Problem 2 Comments: Easy to push storm snow on 35° E @ 7200'. Didn't get to test any other slopes. Low elevations didn't have enough new snow to do anything. Most upper elevation looked to have been transported by wind and was cooled with breeze today.
STABILITY TESTS
 Stability Test Results:
OBVIOUS SIGNS OF INSTABILITY
 Marked with checkmark if observed:
 Cracking (isolated)   Length: 10'
SNOW STABILITY
 Snow Stability Rating for your observed area: Confidence: Trend:
 Comments (aspects and elevations of instability, etc): MOD at middle with more isolated, smaller wind slabs and possible loose wet problem. Not enough snow or warming down low so LOW. Did not get into the alpine but feel like it did deserve CON for the day based on natural activity, apparent wind effects, and drifting at middle elev.
