An Odyssey Of Mars Science: Part 3
Martian Valley networks in Margaritifer Sinus area. This image shows one of the more well defined dendritic valley networks on the heavily cratered terrain in Margariter Sinus at 10 degrees west and 23 degrees south. The image is about 180 kilometers across. Some of the valley heads appear to terminate abruptly in rounded headwalls ("T") that have been cited as evidence that erosion (sapping) by groundwater emerging to the surface has created the valley networks, because similar "theater-headed" valleys are found where groundwater sapping occurs on Earth. In other places, however, the valleys just seem to gradually merge with the inter-crater uplands or to feather out ("F"), suggesting a more diffuse origin of drainage from the surface or near-surface.
