PROFESSIONAL OBSERVATION FORM
 Start Date: 01.04.19 Name: Lundy, Haskins Operation: SAC
 Drainage/Route:  Twin Bowls Observed Terrain:  7900-9100, S-E-N Zone/Region:  Smoky & Boulder Mountains
WEATHER OBSERVATIONS
 HN24: HST: Sky: SCT Precip: Temps:
 Ridgeline Wind: Calm
 Blowing Snow: None Snow Available for Transport: Small amounts
 Comments: High, thin SCT to OVC skies. Warm temps but solar input limited somewhat by cloud cover. Surface of solars, especially those over 30 degrees, became moist 7-10cm deep
AVALANCHE OBSERVATIONS
None Reported
SNOWPACK OBSERVATIONS
 HS: 50-80cm 
 Upper Pack: Shade: surface becoming somewhat faceted but process seems limited by warm temps
Solar: Moist surface 7-10cm deep. Will likely become soft MFcr when frozen. 
 Middle Pack: Shade: 12/11 SH 5mm found at 8600', sheltered NE. Slab is breaking down and generally 4F.
Solars: Found MF/FC/MF sandwich 40cm down in several handpits - likely from 12/11 & 17  
 Lower Pack: Shade: I barely got into upper elevations but 11/22 DH is consolidating somewhat and becoming thinner.
Solar: 12/11 basal FC and DH remains quite weak but moist near the ground. Weakest areas is at top of FC/DH where it meets the crust sandwich mentioned above 
AVALANCHE PROBLEM ASSESSMENT
Avalanche Characteristics
Character/Avalanche Problem:
Persistent Slab

Layer/Depth:
11/22 and 12/11

Likelihood of Triggering
Sensitivity:
Unreactive

Spatial Distribution:
Widespread
Terrain
  Primary Concern Comments: Forecasted distribution. Would need to find somewhere where slab remains intact - recent or old wind affect
STABILITY TESTS
 Stability Test Results: 8600, NE: ECTP 28 on 12/11 SH. Otherwise no significant results
SNOW STABILITY
 Snow Stability Rating for your observed area: Confidence: Trend:
BOTTOM LINE
 Comments: Avalanche danger at mid elevations going to Low. Still some concern for wind affected areas where stiffer snow sits atop the various weak layers.
