Summary
North Pole 90°N
The Moon's North Pole lies north of Mare Frigoris in an old highland region. The craters in this area are often flat (lava-flooded), heavily eroded by secondary impacts and frequently overlap one another. Some, such as W. Bond and J. Herschel, have very rough crater floors, heaped with ejecta from the Imbrium impact, whereas others, such as Meton, have smooth floors and have been covered with Imbrium lava. The whole terrain and many crater rims show structures with valleys, fissures and crater chains, similar to the structures in the southern Imbrium Sculpture near J. Caesar and Ptolemaeus. Because of limb foreshortening the traces in the north are harder to observe. The most clearly recognized are valley-like structures east and west of the crater W. Bond and a long crater chain in J. Herschel.
Meton 73.6°N, 18.8°E
Meton is the heavily eroded remnant of a very large complex crater, 130 km in diameter. Overlapping it are two other large craters, Meton C (77 km) and Meton D (78 km). All three crater floors appear flat and level. Under low solar illumination and in larger telescopes various craterlets become visible on the crater floors. The trio of craters lies north of Mare Frigoris in the Moon's north polar region. Under high illumination, rays of ejecta from the crater Goldschmidt are visible on the crater floor, and which resemble those in the crater Stöfler in the southern highlands.
