Tyrrhena Dunes

May 23, 2006

This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows a portion of a field of dark sand dunes superposed on the light-toned floor of a crater in eastern Tyrrhena Terra. The orientation of the dunes—with the steep faces toward the south (bottom)—suggests that winds generally blew from north to south at the time the dunes were formed.
