This image from ESA’s Mars Express shows the wrinkled surroundings of Olympus Mons (a feature named Lycus Sulci, on the raised aureole surrounding the volcano).
The colours of the terrain represent topography and elevation, ranging from lower blue areas through higher yellow-orange-reds to high peaks of white. The area outlined by the bold white rectangular box indicates the area imaged by the Mars Express High Resolution Stereo Camera on 18 January 2023 during orbit 24056. The smaller inset white box shows the region featured in these new Mars Express images.
