Meton is a compound formation on the Moon that consists of several merged crater rings that have been flooded with lava, forming the remnant of a walled plain in the shape of a clover leaf. It is located near the northern lunar limb, and is viewed from a low angle and foreshortened. The crater Barrow is attached to the southwest rim. To the northwest is the crater Scoresby, and to the east are Baillaud and Euctemon.

Oblique view of Meton from Lunar Orbiter 4. Meton is below center, Meton D is below left of center, Meton C is in upper left, and Meton E is at right. They are all flooded to the same elevation, and the subtle ridges that divide these craters are barely visible in this image.

Baillaud is a lunar impact crater that is located near the north limb of the Moon. The rim of the crater has been eroded and worn by a long history of impacts, leaving a hilly ridge surrounding the interior. The crater Euctemon is intruding into the rim to the northeast, and the rim bulges outward to the northwest. At the south end of the crater is a gap connecting to the lava-flooded surface to the south.
