When we acquired this images, it was late northern spring on Mars, where the southern middle latitudes get very low-sun illumination that accentuates subtle topography.
This image shows sand dunes mixed with rock outcrops on the floor of a large crater. Some of the dunes have squiggly crests, which is unusual. It looks like this is due to the outcrops, which anchor the dune in places as they migrate.
