Caption

This is a perspective view of Nili Patera dune field: The HiRISE image has been draped over a digital elevation model of Mars. Colors correspond to the amplitude of the ripple's displacement extracted by image correlation between two HiRISE observations separated by 105 days. Cool colors (blue) correspond to less than 75 cm of displacement whereas warm colors (red) correspond to 4.5+ meters.
