Computer-generated perspective view of the southeastern corner of the volcanic plains of Amenthes Planum. This view was created using data obtained from the High-Resolution Stereo Camera on ESA’s Mars Express. The image shows a 20-mile-wide (30km) crater, the north eastern rim of which rests against a smooth volcanic trough that may have once transported fluvial and volcanic materials from Palos Crater and Tinto Vallis into Amenthes Planum. // ESA/DLR/FU Berlin (G.
