NASA/JPL/Malin Space Science Systems

This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows a gully formed in the wall of a north middle-latitude crater. Similar gullies are common at the middle and polar latitudes of Mars, and might have formed by the action of liquid water. Others have argued for carbon dioxide or dry mass movement for the genesis of such landforms. This particular image was acquired during northern autumn, when the sky over the terrain of the martian northern mid-latitudes is typically hazy.
