PROFESSIONAL OBSERVATION FORM
 Start Date: 12.02.18 Name: Lundy Operation: SAC
 Drainage/Route:  Titus Ridge Observed Terrain:  8700-9900', most aspects except SW Zone/Region:  Smoky & Boulder Mountains
WEATHER OBSERVATIONS
 HN24: ~8 HST: Sky: X Precip: S-1 Temps:
 Ridgeline Wind: Light from the SE
 Blowing Snow: Snow Available for Transport: Large amounts
 Comments: S-1 from 1130-1400, with periods of S1.
AVALANCHE OBSERVATIONS
None Reported
 Comments: No avalanches observed. Older slides reported in Waltschers Bowl were mostly filled in.
SNOWPACK OBSERVATIONS
 HS: At upper elevations...Solar: 40cm. Shade: 50-70cm. 
 Upper Pack: 40-50cm of snowfall since Thanksgiving (RG, DF, PP). Settling to 4F or 4F+ at base of slab. 
 Middle Pack:  
 Lower Pack: On northerly aspects: 10-15cm of F (more like F-) DH, 3-5mm
Most shaded aspects I looked at had a 5-8cm K hard MFcr at the ground 
AVALANCHE PROBLEM ASSESSMENT
Avalanche Characteristics
Character/Avalanche Problem:
Persistent Slab

Layer/Depth:
11/22, 40cm

Likelihood of Triggering
Sensitivity:
Reactive

Spatial Distribution:
Widespread
Terrain
  Primary Concern Comments: Borderline touchy, but not seeing new avalanche activity
STABILITY TESTS
 Stability Test Results: Pit @9500', NW, 10*, HS=68cm: ECTP4, PST 15/100end
OBVIOUS SIGNS OF INSTABILITY
 Marked with checkmark if observed:
 Cracking (isolated)   Length: 20-30'
 Collapsing (widespread)   Length: 50-100'
 Comments: Numerous muffled collapses, generally not producing any cracking. At least one shook snow off of trees 100' away. I received several collapses walking along the ridge above avalanche terrain, and got one slope to crack a bit, but no remote triggers.
SNOW STABILITY
 Snow Stability Rating for your observed area: Poor Confidence: MODERATE Trend: Steady
