At the time of this observation, winds have been calm and there are no signs of wind affected snow or wind slabs, though there is around 8 inches of low density snow available for transport.

We have received around 8 inches of snow since Friday. This F hard snow sits atop the old snow pack left over from the November 17th storm. The old snow is a mix of crusts and layers of sugary faceted grains. These sugary layers will be important to monitor over the coming weeks as more weight is added to the snowpack.
