PROFESSIONAL OBSERVATION FORM
 Start Date: 03.07.19 Name: Savage Operation: SAC
 Drainage/Route:  glassing mountains from Stanley to Hailey Observed Terrain:   Zone/Region:  Smoky & Boulder Mountains
WEATHER OBSERVATIONS
 HN24: 10-20cm HST: 10-20cm Sky: BKN Precip: S1 Temps: 20s and 30s F
 Ridgeline Wind: Moderate and Intermittent
 Blowing Snow: M Snow Available for Transport: Large amounts
 Comments: Some snow plumes off higher ridges, not much evidence of wind-loading at middle elevations. Upper elevations socked in and snowing around Galena Summit and north, partly cloudy skies near Galena Lodge, clear from about Owl Creek to the south at 3PM.
AVALANCHE OBSERVATIONS
 No. Location Date Size Type Trigger Aspect Elevation Comments
 3 Goat Creek/Goat Peak Today 1.5 SS N SE 9700-10000 3 slides, D1-D2, see photos.
 3 Galena Summit Today 1.5 SS N SE 8900 3 small slides, see photos.
 1 Boulder Peak Today 1.5 SS N SE 10200 Small pocket a ways below ridgeline.
 1 HWY75 near Owl Ck Today 1 WL N SW 7400 Small wet loose slide that I watched happen around 2:30 PM.
 Comments: One of the Goat Peak slides was at the ridgeline and obviously wind-loaded, but the other slides were in sheltered or subtly wind-loaded terrain well below ridgelines.
STABILITY TESTS
 Stability Test Results:
SNOW STABILITY
 Snow Stability Rating for your observed area: Poor Confidence: MODERATE Trend:
 Comments (aspects and elevations of instability, etc): SE aspects at middle and upper elevations. Natural activity was very aspect dependent.
BOTTOM LINE
 Comments: It appears we have a touchy crust+facet issue on SE aspects. Given the recent weather, this problem could be present on W-S-E aspects - but it appears to be most sensitive on SE-facing slopes.
