Swirling Winds Reflected In Dunes

These dark transverse and linear dunes are located in the floor of a crater in the southern highlands. The dunes appear to follow the flow of winds that circle around the crater floor, creating a swirling pattern. Another reason for the apparent arc may be a north to south shift in the relative strengths of two winds that influence these dunes. Dust devil tracks indicate recent wind action on the floor of this crater.
