Caption:
11 August 2006
This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows gullies -- all of which head at the same level -- on a south mid-latitude crater wall. At the 6 meters (~20 feet) per pixel scale at which this image was obtained, the gullies almost appear as if they are the product of a "weeping layer," a porous layer of rock through which a liquid such as water may have percolated until it came to the martian surface at this crater wall, then flowed downslope, toward the crater floor.
