, and the satellite formation Anaximander B lies along the western rim. To the northeast is Anaximenes. In geological terms Carpenter is a somewhat young lunar crater, with features that have not been significantly eroded by subsequent impacts. Certainly it is much younger than the surrounding crater formations. The inner wall displays an appearance of slumping, particularly along the eastern face, and there is some development of

, and is consequently mapped as part of the Copernican System. The interior floor within the sloping inner walls is generally level, but irregular with many small bumps and hills. Near the midpoint is an unusual double central peak formation, with a smaller peak offset to the west and a larger ridge offset to the east. The latter ridge runs southward to the edge of the inner wall.

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Carpenter.
