On 22 May 2004 the High-Resolution Stereo Camera onboard the ESA spacecraft Mars Express obtained image data from a crater with a dune field on its floor with a ground resolution of approximately 16.2 metres per pixel. The displayed region is located at the north-western part of the Argyre Planitia crater basin at about 43° southern latitude and 303° eastern longitude.
The diametre of the crater is about 45 km and it is 2 km deep. In the north-eastern part of this crater is a complex dune field, 7 km wide and 12 km long, which consists of dark, possibly basaltic sands.
