White Sands Razorbacks

White Sands NM

Razorbacks are thin, flaky, preferentially cemented features along crack edges that are either supported on one side by gypsum sand, or protrude out of the dune slopes at an angle of about 50 degrees. Razorback surfaces extend up to a few centimeters above the dune slope surface and are up to a couple millimeters thick. Photo © copyright by Robert Faucher.
