Overcast skies, snowing all afternoon with rates up to S2, moderate westerly winds and occasional light blowing snow in the valley bottoms. Airtemp of -10 C at 1300.

Snowpack

Our group dug several full profiles on a north trending meadow at 10,850 ft. HS averaged 75 cm. Bottom 40 cm is a mix of facets and depth hoar (2.0-4.0mm). Upper portion of snowpack consists of snow since December 13th. The December 13th interface at 40 cm is a faceting MFcr. December storm snow is a variety of faceted grains. We estimated about 10 cm of storm snow fell throughout the day. CTs produced non planar breaks on the DH and PC results on the Dec. 13th interface. Overall, a mostly faceted and weak snowpack
