Martian landscape. This HiRISE image shows landforms on the surface of Mars. Megadunes. These dunes in Hyperborei Cavi are known as 'barchan' for their shape, which typically follows the direction of the wind. In addition, these barchan dunes indicate unidirectional flow and high sand supply. A unique optimised version of NASA imagery. Credit: NASA/JPL/UArizona
