Dunes and Dust Devil Tracks
Caption:
22 August 2004
This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows a suite of dark sand dunes that formed in winds blowing from east (right) to west (left), along with smaller, lighter-toned ripples and many dark dust devil tracks. The dust devil tracks indicate movement from a variety of directions, while the dunes only indicate winds from the east. In the lower left quarter of the image, dune sand has flowed around a layered rock obstacle. This scene is located near 19.9°N, 280.5°W. The image covers an area about 3 km (1.9 mi) across and sunlight illuminates the scene from the lower left.
