Widespread turbulent snow visible along the range

Driving from Mammoth to Bishop, very strong SW winds were causing many areas of turbulent snow in the air at tree-line and above, and even below to an extent.  It looked as though much of this snow was being sublimated into the atmosphere, but I would think that some small sensitive wind slabs were forming in some areas.  Huge banners over ridges and peaks would have been likely from these very strong winds, if only the loose snow available for transport wasn't so limited.  Alot of firm surfaces out there!
