This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) picture shows some of the layered, sedimentary rock outcrops exposed on a mound in Gale Crater near 5.0°S, 221.8°W. These layers represent a long history of sedimentation that occurred in Gale Crater at some time in the distant martian past. Later, these layers were eroded and exposed. Gale Crater may once have been completely filled by these layered materials. The picture covers an area 3 km (1.9 mi) across and is illuminated by sunlight from the left.
