Overall snowpack is faceting. The NYE crust is variable thickness. Facets both above and below. This combo is around 6" to a foot below the surface.
No slab found. No formal snowpack tests.
Probed on the south side of Tenderfoot as well. Snowpack near ridge varied from 130 cm to 200 cm. Also dug in a deeper spot and found old wind deposited snow to ground that was all small facets ( .5mm) overall structure was much different than the shallower snowpack on the other side of the ridge.
The December 9th crust is also very pronounced in all pits with developed facets above.
