Impact Craters and a Scarp


Within the yellow box, three unnamed craters are stacked one upon another. The rim of the largest of the three is partially obscured, and the crater floor appears filled in, likely due to flooding by volcanism. Superposed on this crater is another younger crater, which has also been impacted by an even younger crater. To the north of the craters, a long scarp (yellow arrows) cuts across the region.
