This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows dark sand dunes in the north polar region of Mars. They are streaming away (toward the left) from a low escarpment at the edge of an outlier of polar water ice (the bright area on the right). The picture covers an area about 3 km (1.9 mi) wide and is located near 80.7°N, 80.2°W. Sunlight illuminates the scene from the lower left.
