The Nili Fossae graben system is an area of great geological interest near the giant Isidis impact basin, northeast of the Syrtis Major volcanic province.
The graben system contains numerous troughs, part of one can be seen at the lower left of this image. On the plateau above, several depressions can be seen, some of them extending into the trough. Part of a large, 55 km-diameter impact crater with a central pit can be seen on the top right.
This image was acquired by the High Resolution Stereo Camera on ESA’s Mars Express on 16 October 2014 during orbit 13699. This oblique perspective view was generated using data from the stereo channels. The centre of the associated main colour image is located at about 75°E / 24°N. The ground resolution is about 18 m per pixel. North is to the right, east is up.
