A black and white landscape photo of sharp curving ridges on a sand dune. The image is very high contrast with very black sections of shadows and light gray sections of sunlit sand. A curve runs across the bottom, bright and then dark. Dark shadows and numerous small ridges angle from the center-left to bottom-right. Another wavy ridge line runs from center-left to upper left. It's bright on the left and dark on the right. Light sunlit sand runs across the top of the image.
