This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows the inverted remains of several channels in a fan-like complex in the Aeolis region of Mars. The inverted channels are the flat-topped ridges that trend from lower right toward upper left (southeast to northwest). Other ridges, trending from lower left toward upper right (southwest to northeast) are yardangs, the products of wind erosion. The channels were inverted by erosion, as well -- the tops of these ridges were once the floor of the channels (or the tops of materials that filled the channels).
