ADVANCED OBSERVATION FORM
 Start Date: 01.26.19
 Drainage/Route:  Silver Ck, Snow Ck from Baker Ck parking lot Observed Terrain:  SW-S-SE, 6700-8600' Zone/Region:  Smoky & Boulder Mountains
WEATHER OBSERVATIONS
 HN24: 0 HST: 0 Sky: CLR Precip: Temps: 39F at lot 1PM
 Ridgeline Wind: Moderate and Intermittent from the NW
 Blowing Snow: Prev Snow Available for Transport: None
AVALANCHE OBSERVATIONS
None Reported
SNOWPACK OBSERVATIONS
 HS: 60-100cm below 8600': Few formal observations, just getting off sleds every once in awhile. Appeared to get deeper at upper cirque/canyon mouth at 8600'.  
 Upper Pack: lots of wind affected snow (stiff drifts, soft drifts, scouring, sastrugi, dappled surfaces, wind board softening in the sun, etc) 
 Middle Pack: DF with a denser layer keeping you off the ground in many places 
 Lower Pack: FC/DH, getting moist (only looked when getting sleds unstuck) 
AVALANCHE PROBLEM ASSESSMENT
Avalanche Characteristics
Character/Avalanche Problem:
Persistent Slab

Layer/Depth:
FC/DH above ground

Likelihood of Triggering
Sensitivity:
Not Observed

Spatial Distribution:
Widespread
Where did you find this problem?
  Primary Concern Comments: No collapsing noted, didn't travel on anything over 32*.
 
Avalanche Characteristics
Character/Avalanche Problem:
Wind Slab

Layer/Depth:
15-40cm

Likelihood of Triggering
Sensitivity:
Unreactive

Spatial Distribution:
Isolated
Where did you find this problem?
  Problem 2 Comments: No cracking, and we rode through a fair amount of stiff wind-deposited snow. "Gooey" feeling with the heat and sun today.
 Comments: Based strictly on the look of things, I expect both problems were more significant in the alpine.
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): Rating only pertains to sunny slopes (SE-S-SE) from 6700-8600'.
BOTTOM LINE
 Comments: No obvious signs of instability where we traveled, but we did not ride anything over ~32*. The alpine looked a lot different than where we were riding, widespread wind effects and probably much harder slabs. I would not have trusted wind-loaded slopes >35*. Savage SAC (OFF DUTY)
