Weather Comments: 
A bit inverted, temps were warm and balmy at 10,400 (4°C). As the day progressed the winds drastically increased and the cloud cover rolled in. Even the stiff crusts could be seen getting shattered and flying around in the wind. Uinta's eauals wind and today was no different.
Snow Characteristics
Snow Surface Conditions: 
Melt-Freeze Crust
Rain-Rime Crust
Snow Characteristics Comments: 

Crusty. Some crust may have been from rime, a lot was from melt-freeze and it was very wide spread.  It seemed like the higher we went the more prolific the crust was. Shiny and crusty, super fun. 

Red Flags
Red Flags: 
Poor Snowpack Structure
Avalanche Problem #1
Type: 
Persistent Weak Layer
Trend: 
Same
Problem #1 Comments: 

Garbage pouring out.  Still found a bit of moisture in the basal facets, but it is doing little to heal other than to aid in clumping when squeezed. Where digging today, seemed like less moisture than in other areas in the range. 

Avalanche Problem #2
Type: 
Wind Drifted Snow
Trend: 
Same
Problem #2 Comments: 

Naturals were seen off the backside of Bald. Nothing large, but all in leeward side of the wind.

Comments: 

Pulled this little one out, but only on the second pass after undercutting it the first time. Failed on the top of the basal facets. Snowpack was about half as deep as found elsewhere.  Test slope on the bank of Trial Lake. 

68° E, 9800ft. You can see the shattering of the rime/melt-freeze crust
