- remnants of a large crater buried under the maria basalt, an artifact associated with the impact that produced Aristarchus or an optical illusion?


Great image Brian, in fact neither of those! What you see is the Aristarchus Plateau, it is roughly 200kl wide and rises to about 2kl above the surrounding mare, an island if you like! As to it's formation, I don't know, probably some sort of swelling from below. HTH's.
