Unknown
When astronomers first observed the Moon through a telescope and called those large dark spots seas, they were not wrong, although they did not know the exact truth about them. Those spots are really seas, but made of hardened lava. An example is the western Mare Crisium that looks like a basin with high shores.
Not far from the "shore" we see a "high wave" called Dorsum Oppel.
In this basin we can distinguish among not too many craters, a small one located here, called Peirce (19 km). To its north is a smaller one called Swift (10 km).
