This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows an undulating scene in the south polar region of Mars. Small, elevated mesas of smooth, relatively homogeneous-appearing material are separated by low-lying regions that are speckled and darkened in some local areas. Over the martian summer months, sublimation of solid carbon dioxide -- the bright material in the scene -- contributes to the darkening of the sides of the mesas as well as the low-lying regions between them.
