ADVANCED OBSERVATION FORM
 Start Date: 11.28.18
 Drainage/Route:  Pilot Peak Observed Terrain:  SW-South-SE-E-NE from 6000-8000 feet Zone/Region:  Mores Creek
WEATHER OBSERVATIONS
 HN24: 10 cm HST: 50 cm Sky: OVC Precip: Temps: 0
 Ridgeline Wind: Light and Intermittent from the S
 Blowing Snow: None Snow Available for Transport: Large amounts
AVALANCHE OBSERVATIONS
None Reported
 Comments: Not enough loading to trigger natural releases.
SNOWPACK OBSERVATIONS
 HS: 50-60 cm 
 Upper Pack: New snow - decomposing 
 Middle Pack: Rounds - supportive, good for skiing 0.5-0.75 mm size 
 Lower Pack: Basal facets, +10 cm thick, 3-4 mm size

Layer/Depth:
35-40

Likelihood of Triggering
Sensitivity:
Touchy

Spatial Distribution:
Specific
Where did you find this problem?
  Primary Concern Comments: 
STABILITY TESTS
 Stability Test Results: CTVQ1(SC), ECTP11, PST20/100(END)
OBVIOUS SIGNS OF INSTABILITY
 Marked with checkmark if observed:
 Cracking (isolated)   Length: 10 m
 Collapsing (isolated) Depth: 35 Length: Localized
SNOW STABILITY
 Snow Stability Rating for your observed area: Confidence: Trend:
 Comments (aspects and elevations of instability, etc): Evidence of instability, confidence is moderate due lack of knowledge of basal facet layer distribution. Variability is UNKNOWN. Trending in the short term(24 hours) to STEADY, and deteriorating with a loading event (+24 hours).
BOTTOM LINE
 Comments: By Saturday, once the snowpack is loaded, it is likely that Natural releases will be observed. UNlikely that at mid-elevations there is enough connectivity o the basal face layer to have medium to large avalanches. I expect to small avalanches in the 10-meter range above 7000 feet at N-E aspects.
