 Start Date: 03.31.17 Name: Wieland Operation: SAC
 Drainage/Route:  Peak 2 Observed Terrain:  5600-9500 Zone/Region:  Soldier Mountains
WEATHER OBSERVATIONS
 HN24: HST: 4-25cm Sky: FEW Precip: Temps:
 Ridgeline Wind: Light from the NE
 Blowing Snow: Prev Snow Available for Transport:
 Comments: Surprisingly nice day on Peak 2.
AVALANCHE OBSERVATIONS
 No. Location Date Size Type Trigger Aspect Elevation Comments
 Comments: Observed a few small sluffs that occurred mid-storm but no other avalanche activity observed. A few small cornice chunks fell of in N. Fork Soldier but did not trigger anything.
SNOWPACK OBSERVATIONS
 HS: n/o 
 Upper Pack: No new snow found to 6500'. 2-5cm resting over 4-5cm wet grains from 6500' to 7500' on southerly aspects. 5-20cm on thin crust with 2-3cm wet grains below crust 7500-8500. 15-25cm in sheltered terrain at 8500-9000'.  
 Middle Pack: n/o 
 Lower Pack: n/o 
AVALANCHE PROBLEM ASSESSMENT
Avalanche Characteristics
Character/Avalanche Problem:
Wind Slab

Layer/Depth:
20-100cm

Likelihood of Triggering
Sensitivity:
Stubborn

Spatial Distribution:
Widespread
Terrain
  Primary Concern Comments: Less widespread at middle elevations. Wind loading was on most aspects at upper elevations with wind blowing from all sorts of different directions. All slabs and drifts I encountered were 4F to 4F+. Stubborn on the small tests slopes I traveled on but have a feeling they ranged from stubborn to touchy.
 
Avalanche Characteristics
Character/Avalanche Problem:
Loose Wet

Layer/Depth:
4-5cm

Likelihood of Triggering
Sensitivity:
Unreactive

Spatial Distribution:
Widespread
Terrain
  Problem 2 Comments: All aspects up to 6500' were slush by 1300 but light breeze was helping to keep things cool.
 
Avalanche Characteristics
Character/Avalanche Problem:
Loose Wet

Layer/Depth:
4-6cm

Likelihood of Triggering
Sensitivity:
Unreactive

Spatial Distribution:
Specific
Terrain
  Problem 3 Comments: Top 4-6cm of HST became moist 6500-7900' but breeze also was keeping this surface cooler. Nothing happening during my ride.
STABILITY TESTS
 Stability Test Results: In non or subtly wind loaded areas, ECTN's breaking within storm snow on PP-r. On SE @ 9000' HST shears were resistant on old crust.
SNOW STABILITY
 Snow Stability Rating for your observed area: Confidence: Trend:
 Comments (aspects and elevations of instability, etc): CON/MOD/LOW.
