This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows light-toned rock outcrops, mesas, and buttes in Aram Chaos. Located immediately west of Ares Vallis, Aram Chaos is a large, nearly-filled impact basin. The sedimentary materials that filled the basin have been lithified -- that is, hardened to form rock.
