Ogygis Undae on Mars

• ... 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."

• New article, long enough, sourced enough, all seems neutral and without problem. The hook fact is cited as mentioned above and no paraphrasing issues are apparent. The image is PD and kinda cool looking, so it'd work well for DYK. Checkmark. – Muboshgu (talk) 02:44, 6 September 2017 (UTC)
