This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows dark, windblown sand dunes on the floor of Brashear Crater in the southern hemisphere. The dominant winds responsible for these dunes blew from the southeast (lower right). Grooves on some of the dune surfaces suggest that the sand may be somewhat cemented; the grooves form by wind erosion.
