This color-coded plan view is based on an ESA Mars Express HRSC digital terrain model of the region, from which the topography of the landscape can be derived. The color coding enhances the visibility of the rippling sand dunes which formed in the wind-sheltered sides of the mounds and canyons. Centered at around 40°S and 310°E, the image has a ground resolution of about 23m per pixel. Taken during revolution 10,736 June 6, 2012. // Credit: ESA/DLR/FU Berlin (G. Neukum)
