This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows a frost-covered surface in the martian south polar region. As the seasonal frost begins to sublime away, local variations in surface texture-mostly dendritic cracks, in this case-lead to early defrosting in some areas. Those areas already defrosted appear dark in the image.
