Caption:
14 April 2004
The north polar cap of Mars is nearly surrounded by fields of dark sand dunes. This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows some of the north polar dunes as they appeared in late winter in January 2004. At the time, the dunes were covered with frost. The image is located near 77.8°N, 52.8°W. The image covers an area about 3 km (1.9 mi) across. Sunlight illuminates the scene from the lower left.
