Mesquite Flat Sand Dunes, Death Valley National Park, California

I, Bob, was looking through a folder of photos from a trip to Death Valley in January 2009 when I came upon this image.  The longer I looked at it, the more intrigued I became with the texture of it.  I was on the top of the tallest sand dune in the Mesquite Flat Sand Dune near Stovepipe Wells in Death Valley National Park, California when I took this photo.  I was looking down into a valley of sorts between the dune crests.  The foot tracks along the top edge give you a sense of scale.

I took this photo with the still function of a Sony high def Handycam, so it's not a high resolution image and will probably not look good if it's enlarged very much.
