Snowpit Observations
More detailed information about the snowpack: 

-Left parking at Convict Lake at 7am, full high cloud cover, up ridgeline toward Laurel Mtn to 9,700', gave up on plan to ski east or southeast facing slopes as cloud cover gave no sign of lifting and those solar aspects were showing no signs of softening by 9:30am.  Skied north facing airport bowls and wrapped back to Convict Lake.

-No evidence of instabilities anywhere from 7am to 11am.

-8:15am, 8,000' to 9,100', SE facing slope = no surface softening or moistening.  100% cloud cover, 46deg F / 8deg C air temp.

-Dug pit at 10am, North facing, 8,400', see attached profile.  Old windslab overlying a fairly thick rounding facet layer (fist plus), which stablity tests failed on with moderate force, Q2, but did not propagate.  Top 7cm of this north facing slope was getting wet at this elevation at this time, due to the heat radiation from the cloud cover.  

-This north-facing slope was fairly littered with small rollerballs from previous day which originated around rock bands and trees at about 9,000'.   

-Cloud cover made this day a bit of a bust.  The clouds kept the sun intensity down on solar aspects and didn't allow them to soften, yet radiated enough heat down onto north facing aspects (which previously held cold snow) to moisten and thicken the upper levels of snowpack.  

*SE and E facing slopes did not soften this morning, making for potentially dangerous skinning and riding conditions.  (see attached photo)
