Snowpit Observations
More detailed information about the snowpack: 

We toured up to Jenny Lake, Blaine Mountain in the Northern Swan Range.  Our goal was to get a look at areas that may have been impacted by wind to assess the extent of wind transport and whether or not we could find any formation of wind slabs.  There is obviously a lot of new snow and definite signs of wind transport, but no other signs of instability.  We dug a pit near the ridgeline on an East aspect at 6960 feet.

The snow in the upper 80 cm of the snowpack is not showing much for signs of settling or consolidating.  Density is fairly consistent fist to 4F.  Although there were signs of wind loading, no surface crusts or slabs were forming in this location.

We did find the early December Rain Crust that was 80 cm down and ~4mm thick, but was not reactive in stability tests.

An Extended Column Test and Compression Test were conducted with minimal results.

We did find a knife hard ice layer on the bottom 15cm of the pack.
