This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows remnants of layered materials near the west rim of South Crater, Mars. The composition of these layered rocks is unknown -- are they the remains of sedimentary rocks or accumulations of dust and ice? We'll probably not know until someone visits this area, perhaps centuries from now.
