This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows small barchan dunes on the floor of a crater in western Arabia Terra. Similar dunes are found in most of the larger craters of the region. The steepest slopes on these dunes, their slipfaces, point toward the west-southwest, indicating that dominant winds blow from the east-northeast (upper right).
