This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image, acquired in December 2003, shows light-toned sedimentary rocks (bottom half of image) and dark-toned sand dunes and ripples (top half of image). The light-toned, wind-eroded rocks are formed of ancient sediments; while the dark-toned, wind-blown dunes and ripples are modern sediments. This picture is located in Ophir Chasma near 4.4S, 71.1W. The image covers an area 3 km (1.9 mi) wide; sunlight illuminates the scene from the lower left.
