Snowpit Observations
More detailed information about the snowpack: 

Moderate snowfall with 15-20cm of new snow by 2:30.  Moderate W winds with occasional strong gusts.  Old growth was fairly sheltered, the ridgeline to the west was exposed.  One pit dug 4/5 of the way up (see attached photo).  The temperature profile revealed a temperature gradient >= 10 deg celsius per 10cm for the most part of the pack, great enough to be driving faceting.  The melt/freeze crust that formed before the Dec 11-14 storms was detectable, albeit very thin.  Under this crust the snowpack was consistent facets to the ground.  All stability tests failed in this faceted layer at about 85cm deep, including ECTP with moderate force.  Several inconsistent failures in CT tests in the snow pack above this melt-freeze crust.     Very abnormal continental snowpack at the moment for the Sierras!  On steeper slopes where a thin spot could be encountered where the force of a skier or rider could trigger this layer, a dangerous large avalanche could result.

*fantastic skiing :-)
