This 1.5 meter per pixel (5 ft./pixel) Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows south polar layers exposed on the slopes of a mesa near 74.2°S, 244.6°W. These layers were once more extensive across the region, today only this and a few other remnants remain. The dark streaks were created by spring and summer dust devils that swept across the layered mesa with little regard to the changes in topography. The image covers an area about 3 km (1.9 mi) across. Sunlight illuminates the scene from the upper left.
