Scarps on Ganymede

Original caption:"NASA's Galileo spacecraft took this image of dark terrain within Nicholson Regio, near the border with Harpagia Sulcus on Jupiter's moon Ganymede. The ancient, heavily cratered dark terrain is faulted by a series of scarps. The faulted blocks form a series of "stair-steps" like a tilted stack of books. On Earth, similar types of features form when tectonic faulting breaks the crust and the intervening blocks are pulled apart and rotate. This image supports the notion that the boundary between bright and dark terrain is created by that type of extensional faulting.
North is to the right of the picture and the Sun illuminates the surface from the west (top). The image is centered at -14° latitude and 320° longitude and covers an area approx. 16 by 15 Km (about 10 by 9 miles). The resolution is 20 mt (66 feet) per picture element. The image was taken on May 20, 2000, at a range of 2.090 Km (about 1.299 miles)".
