The thin, dark, angular mesas in depressions in this Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image are remnants of a layer of material that has been largely stripped away from the region. The picture is located in the south polar region near 78.1°S, 272.2°W. Sunlight illuminates the scene from the upper left; the picture covers an area 3 km (1.9 mi) wide.
