Snowpit Observations
More detailed information about the snowpack: 

Near crust faceting processes continue to act on the upper portion of the snowpack. A new layer of faceted crystals was observed just on top of the upper most rain crust, at the base of the recent storm snow. No indications of an unstable slab and weak layer combination in this area despite the presence of several faceted weak layers in the upper snowpack.

Video: NE winds were moderate in speed, but insufficient to cause any wind transport of snow on the ground. No evidence of blowing snow observed on any other surrounding peaks prior to departing the area at 1pm.
