A combination of wind slabs old and new will be your primary concern out there today. Expect to find them liberally scattered throughout the high country on the leeward sides of ridge crests and terrain features such as sub ridges, gully walls or rock buttresses. A subtle variation in terrain can make all the difference, and in some cases, a stiff wind slab may exist adjacent to a scoured surface or even exposed ground. Upwards of a foot of snow has been lying around, available for transport, and with winds of this intensity, drifts will have formed farther down slope than usual. Suspect any steep slope with smooth rounded deposits of wind drifted snow, and avoid slopes with steep convexities and blind break-overs. N-NE-E aspects are the most suspect.

We have a couple of weak faceted layers in the upper portion of the snowpack. Dave Garcia has been experiencing isolated collapsing and has identified a weak layer on WNW aspects around 11,000'. Read his observation here. I have found two, weak faceted layers about 2' below the surface on NE-N-NW aspects between 11,000 and 11,500 feet. They are reactive to stabilty tests scoring ECTP 20-24. The video below illustrates the problem pretty well if you can suffer through the poor sound quality. It gets better the second half, my apologies.
