Observed rain runnels in the snow below 2500' indicating snow that was saturated by rain.  Found 4" of moist new snow up to 3200' sitting on a rain crust, above this elevation the new snow dried out and the rain crust went away.  

In a snowpit at 3500' W aspect, 20° slope.  Found that the Dec 9-10 storm snow is right side up and has consolidated to 35cms.  In this location there was good bonding with the Dec 6-7th snow.  Below this there is a density change at 55cms, snow going from 1 finger to 4 finger.  ECTX.
