This color-coded overhead view is based on an ESA Mars Express High-Resolution Stereo Camera digital terrain model of the region southeast of Amenthes Planum and north of Hesperia Planum, from which the topography of the landscape can be derived. The color coding emphasises the superposed craters on the large 60-mile-wide (100km) crater to the left (south) of the image. Also more clearly seen are the various mesa and buttes within the larger 60 mile crater. At the bottom of the image is a small river valley that feeds into Palos Crater, which may once have hosted a lake. // ESA/DLR/FU Berlin (G. Neukum)
