Weather Comments: 
Brilliant sunshine and scattered clouds in the mountains. Clinging valley clouds deposited a couple inches of snow in Provo Canyon with only a trace at the Aspen grove weather station and nothing up high. Cold enough that south didn't seem impacted, although we didn't ski steep solar aspects to verify. Calm.

Powder

Snow Characteristics Comments: 

Marvelous skiing and easy trail breaking.  Newest snow felt (under foot) higher density than the snow in Little Cottowood felt yesterday.  No real wind affect in our area.  Yet another good storm: Monday's bed surface was Thursday's soft powder.

Comments: 

Dug near the surface on north and east facing slopes at 7,700': neither pit had frightening results: CT Hard Q3 within storm snow between graupel layers on east, and ECTX on North.  5-10mm surface hoar 50 cm down in the north facing pit--however inactive- made us curious to dig in further locations.  North northwest 8,900 feet revealed no surface hoar and ECTX.

We also dug into the crown of the slide in UFO 3: 9800' east facing.  Here the failure plane was 40cm down within the new storm snow, about 8 cm above the old/new interface that preceded this last round of storms.  No sign of surface hoar at this location.  

Avalanche cycle in the rear-view, and likely healed if all activity was in the new snow.  Still, history of widespread surface hoar and it's presence in pit made for some uncertainty (might it be active in just the right spot?) and thus a moderate hazard
