PROFESSIONAL OBSERVATION FORM
 Start Date: 01.22.17 Name: Davis, Linnet Operation: SAC
 Drainage/Route:  Owl Creek Observed Terrain:  7,000-8,900', Primarily SW-S-SE Zone/Region:  Smoky & Boulder Mountains
WEATHER OBSERVATIONS
 HN24: 15 cm HST: 30 cm Sky: OVC Precip: S2 Temps: n/o
 Ridgeline Wind: Moderate and Gusty from the S
 Blowing Snow: M Snow Available for Transport: Small amounts
 Comments: Pre-frontal winds were mixing down to the highway along the Boulders and blowing moderate up the Owl Creek Basin (easterly) for a couple hours early in the tour. Wind eased a bit at 1300; no longer blowing along the creek bottom. Snow began at 1100 was still snowing S2 at 1600. About 15 cm in the skin track near the car at the end of the tour.
AVALANCHE OBSERVATIONS
 No. Location Date Size Type Trigger Aspect Elevation Comments
 1 Across road from Durrance Today 1 SS N N 7,000 Very small, steep, rocky terrain.
 Comments: Saw some debris in a runout of the Austrian Chutes (north-facing, Owl Creek) from the past few days but I couldn't see the start zones. Very flat light off the valley floor and into the alpine.
SNOWPACK OBSERVATIONS
 HS: n/o 
 Upper Pack: A 1-3 cm MFcr formed on SW-S-SE yesterday (1/21). New snow was easily drifting into sensitive 4F->1F slabs 15-30 cm thick. Some fresh drifts of 60 cm were found on exposed middle elevation slopes. The next 15 cm was settled storm snow that was well bonded to the (1/18) MFcr interface. 
 Middle Pack: n/o 
 Lower Pack: n/o 
AVALANCHE PROBLEM ASSESSMENT
Avalanche Characteristics
Character/Avalanche Problem:
Wind Slab

Layer/Depth:
15-30 cm

Likelihood of Triggering
Sensitivity:
Very Touchy

Spatial Distribution:
Specific
Terrain
  Primary Concern Comments: Locally lee to SE wind.
 Comments: Observed terrain had small fetches and non-favorable aspects for ideal loading. Despite this I was surprised how quickly today's new snow formed isolated drifts up to 60 cm thick at middle elevation.
STABILITY TESTS
 Stability Test Results: Numerous hand and pole pits to observe the new/old (1/18) and (1/21) MFcr. Easy, planar shears above (1/21). Rough, resistant shears above and below (1/18).
OBVIOUS SIGNS OF INSTABILITY
 Marked with checkmark if observed:
 Cracking (isolated)   Length: 20'
SNOW STABILITY
 Snow Stability Rating for your observed area: Poor Confidence: HIGH Trend: Worsening
 Comments (aspects and elevations of instability, etc): MODERATE at middle and LOW at lower.
BOTTOM LINE
 Comments: Fresh, very touchy wind slab sitting on the (1/21) MFcr would keep me away from steep, exposed solars at middle and upper elevations.
