Snowpit Observations
More detailed information about the snowpack: 

Unconsolidated snow still exists on N-NE aspects and on E aspects above 8000', crusts exists on lower elevation E aspects.  The 2 crust combo with facets exists in this area on NE and N aspects.  The facets have gained some strength and are more dense than earlier in the week in other areas, 4F hardness today compared to F hardness earlier.  Consistent CT failure in the moderate range just below the upper crust in the facets with Q2 shear failure.  The upper slab, 6-8'', is still soft and not very strong, no signs of possible propagation was seen today with other stability tests and informal ski tests.

HS in this area in the 80-90cm range from 8000-9000'.

Video #1:  2x ECTN

Video #2:  2x PST 100/100 END down in between the 2 crusts in faceted grains.
