Mars Science: Squiggly Sand Dunes
NASA: It is now late Northern spring on Mars, so the Southern middle latitudes get very low-sun illumination that accentuates subtle topography. This image shows sand dunes (http://static.uahirise.org/images/201…) 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.
