DescriptionESP 019287 1180 (44913232311).jpg	To Catalog the Dunes – Believe it or not, the United States Geological Survey does enter these dunes into a global dune database. The reason? “ Dunes are particularly suited to comprehensive planetary studies because they are abundant over a wide range of elevations and terrain types. Thus a global scale study of Martian dunes serves a dual purpose in furthering understanding of both climatic and sedimentary processes.” Sounds good to us!
