4-6" unconsolidated new snow


Very thin snowpack. At 1200' there is about ~12" of snow total. At 2400' there is ~20" total. Off of the the old ski track ski pen was almost to ground and so was boot pen. The snowpack is very weak, with basal facets and faceted snow in the bottom 1/2 of the snowpack. Buried surface hoar was also found below the new snow.

Numerous hand pits all failed easily or on isolation on large grain facets (2mm.) See photos below of the weak snow layers within the snowpack at 2200' and 2400'.
