This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows outcrops of light-toned, layered rock exposed in the central peak of Oudemans Crater, near the Labyrinthus Noctis of the western Valles Marineris complex. The rocks in this August 2005 image were once below the ground and flat-lying. Now they are tilted on edge-a product of the impact that formed Oudemans Crater. Their regular layering and light tone suggest these might be ancient sedimentary rocks.
