Around the western edge of the Moon, a large-scaled crater of Grimaldi with a diameter of over 200km is lying. The inside of crater has been buried by lava, detailed features have been disappeared under dark basalt. Perhaps you will have an impression that the Grimaldi is a small lunar sea rather than a crater. It's suitable around the Moon age of 12 or 13 to observe the lunar surface around this region.
