Elevation of the Sirenum Fossae region in the Southern Highlands of Mars. The image shows the region centred at about 28°S / 185°E. It extends about 230 km by 127 km and covers 29 450 sq km, roughly the size of Belgium.
In the central part of the region is a plateau showing evidence of intense erosion. This image was created using a Digital Terrain Model (DTM) obtained from the High Resolution Stereo Camera on ESA’s Mars Express spacecraft. Elevation data from the DTM is colour-coded: purple indicates the low-lying regions and beige the highest elevations. The scale is in metres.
