This full-resolution (1.5 m/pixel; 5 ft/pixel) Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows gullies on a crater wall in northern Noachis Terra. The gullies might have formed by the seepage of martian groundwater or melting of ice. However, the Mars science community is still studying this topic and no consensus has yet emerged as to whether such gullies could have formed without water. These gullies are located near 32.1°S, 12.9°W. The 300 meter scale bar also equals 328 yards (984 feet). The picture is illuminated by sunlight from the left/upper left.
