This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows a rare patch of dark sand dunes in the Nilosyrtis Mensae region of Mars. The steepest slopes on these dunes, their slipfaces, point toward the south-southwest, indicating that the dominant winds that formed them came from the north-northeast (top/upper right).
