Here’s a picture of terrain between the Kasei Valles and Sacra Fossae fault region on Mars, covering an area of about 225 × 95 kilometres or half the size of the Netherlands.

The image was taken by the European Space Agency’s Mars Express mission, currently in orbit around Mars. The area it has snapped lies north of the equator.

We see a large crater, some 35 kilometres across, and tracks left behind by flowing water at some time in the past. The source of the water, according to ESA is a region called Echus Chasma, which lies roughly 850 km to the southwest of the crater (north is to the right).
