This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows the plethora of large, windblown ripples (or small dunes) among wind-sculpted sedimentary rocks in eastern Candor Chasma. Candor Chasma is one of the troughs of the Valles Marineris, a system of chasms that would stretch all the way across North America if it were on Earth. This picture is located near 7.9°S, 64.9°W. Sunlight illuminates the scene from the left/upper left.
