PROFESSIONAL OBSERVATION FORM
 Start Date: 02.23.19 Name: Lundy Operation: SAC
 Drainage/Route:  Iron Cr/Goat Cr Divide Observed Terrain:  6500-9100', SE-E-NE Zone/Region:  Sawtooth Mountains
WEATHER OBSERVATIONS
 HN24: 2-3cm HST: Sky: X Precip: S-1 Temps:
 Ridgeline Wind: Moderate and Gusty from the SW
 Blowing Snow: M Snow Available for Transport: Small amounts
 Comments: Cold, stormy day. Windier than expected, with steady M speeds and regular S gusts. Moderate amounts of snow being transported, enough to fill in skin track on ridgeline. Not much new wind slab formation observed.
AVALANCHE OBSERVATIONS
None Reported
SNOWPACK OBSERVATIONS
 HS: 80cm on valley floor to 200-250cm on sheltered mid elevations. Obs below are from pit at 8800', ESE had 240cm HS 
 Upper Pack: 85cm storm snow since 2/2, F to P at base of layer 
 Middle Pack: 2/2 MFcr = 1cm thick, P hard. No facets observed on top of crust. 
 Lower Pack: n/o, but 30cm of softer snow could be felt at base of snowpack 
AVALANCHE PROBLEM ASSESSMENT
Avalanche Characteristics
Character/Avalanche Problem:
Wind Slab

Layer/Depth:
today, up to 15cm

Likelihood of Triggering
Sensitivity:
Stubborn

Spatial Distribution:
Isolated
Terrain
  Primary Concern Comments: Observed wind transport but didn't find any sensitive fresh wind slabs.
 
Avalanche Characteristics
Character/Avalanche Problem:
Persistent Slab

Layer/Depth:
Date?, 40-50cm

Likelihood of Triggering
Sensitivity:
Unreactive

Spatial Distribution:
Widespread
Terrain
  Problem 2 Comments: Defined basal FC/DH layer could be felt below around 7000'. No collapsing. Something to keep in mind with more load.
STABILITY TESTS
 Stability Test Results: Pit at 8800', ESE, 31*: ECTX and CTN on 2/2 crusts 85cm down
SNOW STABILITY
 Snow Stability Rating for your observed area: Confidence: Trend:
 Comments (aspects and elevations of instability, etc): More wind transport than expected, but saw very little actual wind slab formation. Wind seemed gusty and swirly - not ideal for slab formation.
