PROFESSIONAL OBSERVATION FORM
 Start Date: 03.17.19 Name: VandenBos Operation: SAC
 Drainage/Route:  Glassing Boulders, Morgan Ridge Ski Observed Terrain:  6,100-8,600 Zone/Region:  Wood River Valley
WEATHER OBSERVATIONS
 HN24: 0 HST: Sky: Precip: Temps:
 Ridgeline Wind: Calm
 Blowing Snow: Snow Available for Transport: None
 Comments: Thin, high clouds limited radiation intensity
AVALANCHE OBSERVATIONS
None Reported
 Comments: Observed ~15 WL slides in the Boulders from the past few days, everything I saw (from a distance) appeared to be smaller than D2. Observed several similar sized slides in the Pioneers. All observed WL activity appeared to be confined to the upper portion of the pack, nothing gouging deeper yet. Looked for WS other than those reported by Davis but light was pretty flat and I couldn't pick out any obvious ones

BOTTOM LINE
 Comments: Lower and mid elevation WRV snowpack seems to be dealing with the transition pretty well, so far. Thin, high clouds limited radiation intensity and slowed down the transition somewhat. Upper snowpack is beginning to develop a decent drainage system, which is a bit of a double edged sword at this point. Near surface WL problems should be somewhat muted thanks to this, but the water has gotta go somewhere. If its not hanging out on top its getting drained into the pack. It would be interesting to see how steeper, cold aspects at middle elevations are behaving and how much ambient melting is affecting the snowpack there.
