This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows a mesa and two hills-each of them a remnant of formerly more extensive layered material--in the south polar region of Mars. The dark streaks were formed by passing dust devils. This picture is located near 64.6°S, 340.5°W. The image covers an area about 3 km (1.9 mi) across. Sunlight illuminates the scene from the upper left.
