This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows light-toned, layered, sedimentary rocks exposed by erosion in Terby Crater, located on the north rim of the Hellas Basin. Sedimentary rocks are common on Mars; the light tone of the rocks here suggests that they might bear some similarity to the sedimentary rocks of Meridiani Planum, explored by the Mars Exploration Rover, Opportunity. Water was likely involved in the alteration of the rocks, and perhaps in their deposition as sediments, long ago.
