High-Resolution Stereo Camera (HRSC) nadir and color channel data taken during revolution 10532 on 17 April 2012 by ESA’s Mars Express have been combined to form a natural-color view of the Melas Dorsa region. Centered at around 18°S and 288°E, this image has a ground resolution of about 18 m per pixel. The image shows the wrinkle ridges bisected by crustal displacement faults known as ‘en-echelon’ faults along with the large impact crater with its butterfly-shaped fluidized ejecta blanket. En-echelon faults are closely spaced, parallel overlapping or step-like fault structures, which in this view can be seen at the far left of the image, intersecting the wrinkle ridges.
