 Drainage/Route:  Sun Mt - Trail Ck and Lake Ck Observed Terrain:  6150-7650', all aspects but due N Zone/Region:  Wood River Valley
WEATHER OBSERVATIONS
 HN24: 0-trace HST: 0-trace Sky: SCT Precip: Temps: 30s and 40s F
 Ridgeline Wind: Light and Steady from the SW
 Blowing Snow: L Snow Available for Transport: Small amounts
 Comments: I was out from 3:45-5:30 PM. All shady slopes above 6300 were refreezing on the way down.
AVALANCHE OBSERVATIONS
None Reported
SNOWPACK OBSERVATIONS
 HS: variable, 0 to about 120cm at the deepest but mostly 40-80cm.  
 Upper Pack: Lots of melt-freeze/corn below about 7000'. Melt freeze on W-SW-S to 7650'. Mixed bag of crusts, and moist/damp recent snow on NW-N-NE-E above 7000'. Glazed wind slabs on SE-E-NE above about 7400'.  
 Middle Pack: Mostly moist/damp melt freeze crystals, frozen and supportable.  
 Lower Pack: Not closely observed. Damp/moist melt freeze crystals for the most part on W-SW-S-SE aspects.

BOTTOM LINE
 Comments: Minimal wind loading from the snow earlier this week - isolated to at/just below ridgetops and cornices above 7400'. With the hard freeze last night and steady breeze today, it wasn't warm enough for wet loose issues to develop. Corn conditions were widespread below about 7000' and on sunnier aspects above that. Shady slopes and marginally shady slopes still had "newer" snow on the surface that was going through melt-freeze metamorphism.
