More detailed information about the snowpack: 

2x RB4 WB down 30cm (Dec 12th) on 33 degree incline, N/NE windloaded slope at provided lat long. On the first RB (video) note the initial WB failure at 5cm - this newly formed wind packed failed on buried surface hoar. Where 2nd RB performed, just 5m adjacent on a very slightly more wind affected slope, this SH layer was not observable. 5x Sudden Collapse CTs on Dec 12th at this same location. Distinct perc tubes in Dec 2nd facet layer.

Another party reported RB4 WB down 20cm on Dec 12th facets in the Davis or Winters Creek drainage, and similar perc tubes in Dec 2nd layer.

Dec 2nd facet layer widespread. Dec 12th facet layer isolated to NW, N, NE, E aspects without wind deposits directly on previous crust.
