Nereidum Montes (IMAGE) European Space Agency Caption High-Resolution Stereo Camera (HRSC) nadir and colour channel data taken during revolution 10736 on 6 June 2012 by ESA's Mars Express have been combined to form a natural-color view of Nereidum Montes. Centered at around 40°S and 310°E, the image has a ground resolution of about 23 m per pixel. It shows a portion of the extensive region, with concentric crater fill in many of the craters towards the east (lower part of the image). Undulations in crater floors are commonly seen in mid-latitude regions on Mars and are believed to be a result of glacial movement. Credit ESA/DLR/FU Berlin (G.
