This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows a portion of a field of dark sand dunes on the floor of an unnamed crater in western Arabia Terra near 7.3°N, 353.4°W. The dominant winds responsible for the movement of sand through this system blows almost directly north to south (top to bottom). The image covers an area about 3 km (1.9 mi) wide, and is illuminated by sunlight from the upper left.
