A Piece of Mars: The rippled darker patch in this 600×600 m (0.37×0.37 mi) scene is the former site of a sand dune. This is one of a few “dune corpses” found just upwind of a dune field in Holden crater. The dunes are migrating to the south and east – you can see that the arc of this former dune opens to the south, the way a barchan slip face would. This dune is what’s left behind after most of its sand has migrated downwind. (HiRISE ESP_052367_1540, NASA/JPL/Univ. of Arizona)
