Perspective view of a wind-blown dune field inside an unnamed, 48 km-wide impact crater in the southern highlands of Mars. The dune field includes sickle-shaped dunes known as barchans, and parallel ridges of dunes called transverse dunes. A smoothly distributed sand sheet stretches between the dunes and the western wall of the crater, and a single elongated transverse dune extends beyond the main field. Dunes can also be seen in the crater to the right in this scene.
This oblique perspective view was generated using data from the Mars Express high-resolution camera stereo channels. This scene is part of the region imaged on 16 May 2017 during Mars Express orbit 16934. The main image is centred on 248°E / 59°S. North is to the right.
