Craters upon craters

Craters upon craters
Craters upon craters Dawn observed this tortuous landscape at 70 degrees north latitude on Feb. 4, 2016, from its current mapping orbit at an altitude of 240 miles (385 kilometers). The impact that formed the lower crater partially obliterated the older one above. As in the previous picture, sunlight comes from the right. Look carefully, especially in the newer crater, to see large boulders, which are bright on the right, as described in more detail here. You can also see streaks of bright material on the crater wall. Full image and caption. NASA / JPL-Caltech / UCLA / MPS / DLR / IDA
