Weather Comments
Day started out with overcast skies and around 1400 there was a brief period of scattered with enough solar to adversely effect the southerly aspect at mid elevation. Winds remained light out of the WNW and appeared to be only a factor on the highest peaks. Tempertures rose rapidly to day and hit the mid 30's at mid elevations.

Snow Characteristics Comments

Overnight there was a 1.5 mm rime crust that was deposited/observed from 8000 to 9800 feet. See above regarding solar damage and resulting melt freeze crusts. The good riding from the last two days took a severe hit, and now there is a zipper crust out there that is ridable but definitely not the quality of turning we had been enjoying during the past two weeks.

Poor Snowpack Structure
Red Flags Comments
Travel today was not in any of the wind loaded and or effected terrain. The past weeks avalanche occurrances appear to have a direct correlation to the poor snowpack structure that has been present for much of the season. The upper Cottonwoods appear to have HS's that offer the possibility for helping the snowpack to heal in this zone, but confidence remains low to safely attack steep terrain in many locations.

Loose wet activity was limited today in the mid elevations due to the thick cloud cover, but with the temperatures forecast to rise at least another 10 degrees on Monday in combination with clear skies, this problem should excalate at mid and upper elevastions. 

Danger continues to be a high consequence Moderate due to the persistent slab problem.
