Parallel ripples of sand extend vertically from the bottom to the top of this panorama, partially covering some flat, light-colored rocks. Crossing the ripples from lower left to upper right is a trough mostly filled with sand, but with a few flat rocks exposed along its sides. In the distance, toward the top of the image, is a small, round, sandy crater. At the top of the image is a flat horizon.
