(IAU Directions) COLOMBO.--A fine ring-plain, about 50 miles in diameter, situated in the highlands separating the Mare Foecunditatis and the Mare Nectaris. The wall, rising at one place to a height of 8,000 feet above the floor, is very complicated and irregular, being traversed within by many terraces, and almost everywhere by cross-valleys. Its shape is greatly distorted by the large ring-plain a, which abuts on its N.W. flank. It loses its individuality altogether on the S., its place being occupied by two large depressions, and lofty mountains trending towards the S.W. In the centre there are several distinct bright elevations.

- Named for Christopher Columbus (1451 – May 20, 1506), a navigator and colonialist who is one of several historical figures credited as the first European to discover the Americas. Though likely not the first to reach the Americas from Eurasia, it was Columbus' voyages that lead to general European awareness of the hemisphere and the successful establishment of European cultures in the New World.
