More detailed information about the snowpack: 

Went to the slopes below Simpson Peak today.  There was 2" of snow in the parking lot and was snowing all morning up until about 1 PM.  In total, storm totals look to be about 4 to 6" with snow falling as graupel.  Did not observe any wind slabs developing.  Several north facing slopes that did not run during the 11/30 avalanche cycle had depth hoar on the ground with 1F to Pencil hard slabs from previous wind events.  Supportable slabs above 10,500' make travel easy and a little bit of new snow really improved the skiing.  

Stability tests continue to indicate moderate force to collapse the weak facets on the ground with the ability to propagate.  

Photo 1: This storm consisted of mostly graupel with about 4 - 6" of new snow 

Photo 2: Graupel pooling below cliff bands

Photo 3: A quick pit showing a slab over depth hoar on the ground.  ECTP 17 on the depth hoar in this pit.
