This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows a portion of the south polar residual cap. The darkened edges of the pits and mesas are evidence of the removal—by sublimation—of frozen carbon dioxide during the recent martian summer. Summer ended and autumn began the day this image was acquired in January 2006.
