This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows light-toned, layered, sedimentary rock outcrops in an unnamed crater located at 8°N, 7°W. Dark, windblown sand enhances the contrast in this view. Hundreds of layers of repeated thickness and physical properties suggest that a cyclic or at least episodic process acted over a considerable period of time to deposit these materials in the crater. At the time the sediments were deposited, the crater might have hosted a lake.
