Dark Names
image by Howard Eskildsen
Howard is a systematizer. He uses his images to establish order and to make information visual. This is a reduced version of one of a series of images Howard has made to identify named features on the Moon, in this case the dark areas. This view shows how many small patches of mare received names - (I doubt if Lacus Excellentiae really is) - and that one large patch has no name related to its mariness. Grimaldi is the name given by Riccioli for the walled ring plain near the western limb that contains a conspicuous patch of mare lava. In the 1960s the walls of Grimaldi were recognized to be the inner ring of a two ring impact basin. In general, maria within basins are named so this really should be Mare Grimaldi.
