Winter View of Dunes

Looking a bit like chocolate mountains with forests of chocolate pine trees, these are in fact dunes from the southern hemisphere on Mars during the winter-time. The brighter tones are thought to be carbon dioxide or water frost. This is an enhanced-color view generated from images acquired by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA’s Mars Reconnaissance Orbiter (MRO).
