The new HRSC image shows the ancient highlands of Arabia Terra. This region lies between two major outflow channels – the meandering Mawrth Vallis to the north and Ares Vallis to the southwest (see context map). Mawrth Vallis is particularly known for its diverse mineralogy, including hydrated sulfates and clays that formed in the presence of water. Looking at the image, one feature immediately stands out: craters, craters, and more craters. It is indeed a heavily cratered landscape. The most prominent feature is the approximately 130-kilometre-wide impact crater on the right-hand side, known as Trouvelot Crater, of which the image shows the western half (see annotated image). In addition to Trouvelot, the scene includes three other large impact craters and countless smaller ones.
