Ogygis Undae
- ... that the Martian dunes of Ogygis Undae (pictured) consist of two different sand types, and look similar to the dunes in Grand Falls, Arizona? Source: "The variation in the Ogygis Undae abundances could be explained by a bimodal distribution of two sand types. An analog of this distribution is seen in Grand Falls, AZ. This dune field exhibits visual similarity to images taken from ripples on Mars. These terrestrial dunes are composed of fine-grained quartz sand and coarse-grained basaltic sand, derived from two different sources."
