Elevation of Melas Chasma region on Mars

Melas Chasma is part of the huge Valles Marineris rift valley, which stretches for more than 4000 km across the face of Mars. Melas Chasma itself sinks 9 km below the surrounding surface, making it one of the lowest depressions on Mars. 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 are colour-coded: purple indicates the lowest-lying regions, and beige the highest elevations. The scale is in metres.
