Martian Dunes

November 1, 2012
This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows a group of small, dark sand dunes trapped along an arcuate ridge. The ridge probably marks the location of a partially-buried, eroded, and filled meteor crater. The dunes are located in Noachis Terra near 45.1°S, 322.0°W. The image covers an area approximately 3 km (1.9 mi) across and is illuminated by sunlight from the upper left. MGS MOC Release No. MOC2-904, 8 November 2004
