With a length of 600 kilometers and a depth of up to two kilometers, Mawrth Vallis is one of the biggest valleys on Mars and a possible landing site for the ESA ExoMars and NASA Mars 2020 missions. It is entrenched in the Arabia Terra highland, which is more than four billion years old, and ends in the great Chryse Planitia lowland region. This 9-image mosaic High Resolution Stereo Camera (HRSC) on board the European Mars Express spacecraft covers an area of ~330,000 square kilometers on the transition from the southern Martian highlands to the northern Martian lowlands. Mawrth Vallis is at the centre of the image. For the full-resolution version, see here.

False color image of the topography of the region around Mawrth Vallis
Digital terrain models of the Martian surface can be generated with an accuracy of up to 10 meters per pixel from the nadir channel directed vertically onto the Martian surface and the stereo channels of the High Resolution Stereo Camera (HRSC) on Mars Express. In this color-coded image, the absolute elevations above a reference level, the Aeroid (derived from Ares, the Greek word for Mars), are well depicted. These elevation values can be read based on the colour scale at the top right of the image. For the full-resolution version, see here.
