South Polar Mesas
December 13, 2003
This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows mesas -- the eroded remnants of a former layer or group of layers -- in the south polar region of Mars. The circular feature at the top of the image is an old meteor impact crater that has been somewhat covered by younger materials; a remnant of the layer that comprises the mesas is also found on the floor of this crater. The image is located near 79.3°S, 299.0°W, and covers an area 3 km (1.9 mi) wide. Sunlight illuminates this scene from the upper left.
