The largest crater in this picture is Aratus D in western Mare Serenitatis. Its circular outline, high rim, and deep bowl-shaped interior are characteristic of many impact craters of comparable size and age. The next largest crater is tear shaped and nearly rimless. It is, furthermore, associated with a rille (arrows). These differences strongly suggest that it was formed or at least highly modified by structural collapse. -D.H.S.
(See Figure 82 which is the same image but shows much larger area. Also, see Figure 226 which is a close-up of an unusual feature from that original image. - Francis Ridge)
