Snowpit Observations
More detailed information about the snowpack: 

Snow pit at 7,600’. NW Aspect off a sub-ridge that gets some loading. HS = 160 cm.  HST 80cm, right side up.  Two thin zipper crusts at about 100 cm below surface separated by 3” of rounds (freezing fog?).  Basal facets were in good shape, sub- millimeter and rounding.  Two attempts at ECTs, both ECTN.  Column just feel apart under body weight.  No real results on CT.  Overall a solid snow pack IN THIS AREA.  Snow below 6,000’ still unconsolidated and early season.  Trail breakers fell into 5-6 holes around logs and bushes, some very deep and inconvenient.

Snow seemed surprisingly stable in this area.  The only signs of recent activity were viewed in the gullies shown in the 2nd photo.  It looks like they ran as sluffs, no visible crowns, during the storm.  Very little sluffing whiles skiing pitches >35 degrees.

Overall a moderate hazard in this area, we traveled to approximately 8,500.  I wouldn’t be surprised if the increasing winds create some areas of easy to trigger wind slabs later in the day or in the future.
