Sand dunes often accumulate in the floors of craters. In this region of Lyot Crater, NASA’s Mars Reconnaissance Orbiter (MRO) shows a field of classic barchan dunes on Jan. 24, 2018.<\/p>\n

Just to the south of the group of barchan dunes is one large dune with a more complex structure. This particular dune,\u00a0appearing like turquoise blue in enhanced color<\/a>, is made of finer material and\/or has a different composition than the surrounding.<\/p>\n
