This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows gullies on the wall of a martian south mid-latitude impact crater. The channels in each gully head beneath an eroding overhang of layered rock, providing support for the hypothesis that some -- if not all -- martian gullies result from release of groundwater to the surface.
