THEMIS Image of the Day, December 11, 2018. In the center of this VIS image is a crater rim, which is shared by two craters. The crater with the deeper floor is at the bottom of the image, and this part of the rim has deeply incised channels.
The crater to the top of the image has a relatively higher floor. In this image, as well as some other similar cases, it is difficult to identify the younger crater.
