Toured up the moraine benches (triple threat) from the end of the plowing ~2mi before the Lundy Lake Dam up until ~10,700' towards Mt Warren.  I was searching for a true west facing slope, and when I finally got to one at 10,700', it was stripped bare. Tons of wind effects at all elevations, and very strong SW winds above treeline.  See photos of raised tracks and sastruggi in more exposed areas.  Couldn't find any areas of sensitive wind deposits in the non-complex mellow terrain traveled.  A few hand pit tests in more recent deposits failed with hard force.  Results definitly not representative of a steep leeward slope under a ridgeline though, where it wouldn't be surprising to find sensitive wind slabs.  

Dug a pit on NW facing sheltered slope not far down from the broad ridge at 9600' and found 85cm of right-side-up storm snow (pencil to fist+) ontop of the ground ... kind of surprised to see no old snow here at all.

Dug another pit at 8800', NE aspect, see attached profile.  65cm last week's storm snow ontop of 30cm facets, ECTP25 in facets.
