This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows sand dunes in the martian north polar region in mid-spring, July 2004. In summer, the dunes will be dark. As they defrost, dark spots form on their surfaces. This image is located near 82.8°N, 219.6°W. The image covers an area about 3 km (1.9 mi) across and sunlight illuminates the scene from the lower left.
