Snow surface

4" fluffy new snow


4" of new snow on soft settled snow. Interface had a layer of surface hoar (November 25). 10-15 total inches of snow over the November 16th layer of buried surface hoar. No cracking, collapsing or recent avalanches observed. The new snow had minimal sign of wind effect. The snow below had been wind effected and felt a bit upside down and grabby in places above treeline. Walking along the ridge above Hippy Bowl showed no sign of wind slab.
We dug a pit at 3200' SW aspect near the top of the up-track to ski Common and the remote triggered slide in Hippie Bowl from Tuesday (November 22). HS: 145 cm. The buried surface hoar is still very prominent in the pit wall down 30 cm (almost a foot). The Extended Column propagated across the whole column on 12 medium taps on this layer as did the Propagation Saw Test. Propagation was initiated at 25 cm of cutting and went to end. Both of these results confirm that the surface hoar layer still has the potential to be initiated and avalanche. It is spooky that the surface hoar is upright and intact in the snowpack, especially near ridgeline start zones.
The light new snow will easily be transported with any sustained winds.
