Snowpit Observations
More detailed information about the snowpack: 

Ski penetration on our skin up to the NE bench below Carson Peak was 35cm, and a hand shear test en route showed a moderate planar reaction at 45cm down. We dug our pit at 8662ft on an ENE aspect at around 2:15pm, with -6C air temp and -7.5 surface temps, light winds increasing to moderate later in the afternoon, along with increasing clouds resulting in precipitation during our descent.  The snow pit showed a significant layer interface at 57cm above ground, between relatively new storm cycles and the old snow which had gone through several melt freeze cycles.  Even though this layer interface produced more yellow flags, the less obvious interface at 72cm produced CT17 RP, and ECTN13 (fracture was initiated but did not propagate). This interface probably divided the new snow that fell in yesterday's storm from last week's event. Decreasing temps throughout the day and increasing cloud coverage. New snow from yesterday did not react from ski cuts or jumping on convex rolls, and seemed to be bonding relatively well with the older snow beneath.  We didn't witness or trigger any slabs or wet loose activity throughout our day. At least 30cm of SN above 8000ft gave us some great pow turns down through the trees and back to the car.

More detailed information about the weather: 

Started out with bluebird skies and below freezing temps at 12pm at 7400ft. As we were digging our pit at 8662ft, clouds and winds increased from FEW to SCT, and L-M but stayed southerly.  As we transitioned to skiing back down to our car, the new storm brought some light snow precip and slightly decreasing air temps.
