This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows a portion of a martian valley, perhaps long, long ago carved by a liquid such as water, in northern Terra Cimmeria. The channel that might have once run down through the valley is no longer visible; the floor is covered with large, light-toned, windblown ripples.
