Several potential weak layers observed near Squaw Ridge

Multiple weak layers observed near the surface in this area today. Primary concern is a faceted layer just under the recently buried crust (photo) that produced SP results on compression tests. But facets were also observed above this crust, and also a less developed faceted layer at the surface. Finally, two surface hoar layers; one buried 1-2 inches from the surface and one on the surface. The buried SH layer was most often observed laying down on sunny slopes or slopes exposed to the wind, and standing up on shaded, wind sheltered slopes, but this wasn't always consistent. Still no slab observed above any of these weak layers, but there was plenty of lightweight snow on W aspects for future wind transport.

Deeper faceted layer was probed at over 100cm from the surface in many areas, and the probe just dropped when reaching this layer. On a NW aspect near treeline at 9000ft, a PST on this layer showed propagation potential, with a PST 50/100 (end) down 90cm.
