Charles Wood refers to this "ghost" crater in his book The Modern Moon, and he says it was named "Ancient Newton" by Johannes Schroter. However, he goes on to say there is no clear evidence that it is actually a buried crater on the floor of the Imbrium basin; it may just be a circumstantial combination of ridges, wrinkles and a few conveniently-placed peaks that our eyes interpret as a ring.Chris Hooker
