This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows the remains of a once more laterally extensive layer overlying undulating terrain very near the south polar residual cap. Removal of the overlying layer has created "windows" through which are revealed topographic variations in the underlying material, predominantly manifested in the form of ridges which run diagonally, from the southwest (lower left) to the northeast (upper right), across the scene.

Location near: 86.9°S, 196.0°W
