Kasei Valles Flows

October 26, 2013
This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows flow materials—on the east/right side of the image—that have come in among a suite of sharp ridges and grooves on the floor of the vast Kasei Valles system. The ridges and grooves are much older and are believed to be the result of a giant, catastrophic flood. The flows might have been mud or lava that ran part way down the ancient valley at a later date. MGS MOC Release No. MOC2-1264, 28 October 2005
