ADVANCED OBSERVATION FORM
 Start Date: 01.04.19 End Date: 01.04.19
 Drainage/Route:  Galena Pass Observed Terrain:  9260 SW- Zone/Region:  Smoky & Boulder Mountains
WEATHER OBSERVATIONS
 HN24: HST: Sky: CLR Precip: Temps: 1.5
 Ridgeline Wind: Calm and Steady from the E
 Blowing Snow: None Snow Available for Transport: Small amounts
AVALANCHE OBSERVATIONS
None Reported
SNOWPACK OBSERVATIONS
 HS: 65cm shaded aspects still hold good snow, southerly aspects are variable with the large sway of temperatures 
 Upper Pack: Primarily composed of decomposing fragments,  
 Middle Pack: Two defined layers of Facets 54cm and again at 35cm from ground (I am definitely suspect of these persistent weak layers, however they were not reactive to standardized tests today) 
 Lower Pack: 13cm of 3mm Basal Facets (Reactive to compression test CT12 SC Q1)

BOTTOM LINE
 Comments: It looks like the snow pack in this region has a number of red flags causing me to step back. The first and most obvious is the 13cm layer of basal facets, secondly there are two layers of concern at 54cm and 35cm. I suspect these layers will become reactive as additional loading occurs.
