MGS MOC Release No. MOC2-369, 23 May 2003
Dark, windblown sand dunes have over-ridden a suite of low, somewhat rectilinear ridges on the floor of an impact crater near 36.5°S, 219.0° W, in this Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image acquired in May 2003. The dune field is located in Terra Cimmeria. The image is 1.2 km (3/4 mile) wide; sunlight illuminates the scene from the upper left.
