This oblique perspective view of Lycus Sulci was generated from the digital terrain model and the nadir and colour channels of the High Resolution Stereo Camera on ESA’s Mars Express. It shows wrinkled, ridged terrain lying at the edges of the ‘aureole’ of Olympus Mons, Mars’s tallest and most imposing volcano. These ridges, created by landslides and lava-driven rockfalls, have become more prominent over time due to ongoing erosion by wind.
Image description: This tan-coloured patch of Mars's surface shows Lycus Sulci, on the aureole of Olympus Mons. Lycus Sulci is a patch of deeply textured and wrinkled ground, resembling lots of uneven ridges rising from the terrain. This image offers a close-up perspective view as if looking down over and across the region, with the ridges stretching away from the viewer.
