Archimedes (83 km) is located on a "clean" area except its western part, on which are some heights called Montes Archimedes, named after the crater.
This crater is the largest of all that are on Mare Imbrium, and is a circular flooded one without central peaks, but only very small craters scattered on its floor. On the floor we can observer some whitish stains, which are most likely remnants of the impact that created the crater Autolycus (39 km), at east.
