Belts of Glaicers (IMAGE) University of Copenhagen - Niels Bohr Institute Caption Mars distinct polar ice caps, but Mars also has belts of glaciers at its central latitudes -- between the blue lines between the latitudes 300-500 in both the southern and northern hemispheres. A thick layer of dust covers the glaciers, so they appear as the surface of the ground, but radar measurements show that there are glaciers composed of frozen water underneath the dust.
