This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows two circular features in the south polar region of Mars. The circular features are degraded impact craters. The dark, irregular features in each crater are the remnants of a layer of material that probably once covered the entire scene, before being eroded away. All of the terrain in this image is covered by defrosting, seasonal carbon dioxide frost.
