Material in the central peaks of lunar craters may come from depths as great as 12 miles (19 kilometers). ... Farther out are patches of debris and, in many cases, irregular secondary craters, also known as secondaries. Those craters come in a range of shapes and sizes, and they are often clustered in groups or aligned in rows.

"Notice there are only a few small craters dotting the surface, so the rim is well preserved. "To a lunar geologist the lack of impact degradation on a surface like this indicates a relatively young age, currently mapped as an Eratosthenian-aged crater.
