Mare Frigoris

Mare Frigoris (Latin frīgōris, the "Sea of Cold") is a lunar mare in the far north of the Moon. It is located in the outer rings of the Procellarum basin, just north of Mare Imbrium, and stretches east to north of Mare Serenitatis. It is just north of the dark crater Plato.

The basin material surrounding the mare is of the Lower Imbrianepoch, while the eastern mare material is of the Upper Imbrian epoch, and the western mare material is of the Eratosthenian epoch.
