Mare Insularum

Mare Insularum /ɪnsʊˈlɛərəm/ (Latin īnsulārum, the "sea of islands") is a lunar mare located in the Insularum basin just south of the western Mare Imbrium. The basin material is of the Lower Imbrian epoch, with the mare material of the Upper Imbrian epoch. The mare is bordered by the craters Copernicus on the east, and Kepler on the west. Oceanus Procellarum joins the mare to the southwest. The name was suggested by lunar geologist Don E. Wilhelms.
