The day before I took this shot of Death Valley's Mesquite Dunes there was a raging sand storm with wind gust up to 70 mph that lasted into the night. The next morning it was still very windy so I decided to head up the west side of the dunes to be upwind, and also so I could catch the blowing sand in the light coming from the east. It's a kind of weird comp but does convey the conditions fairly well.
