Walker is a lunar crater that lies on the far side of the Moon. It is located to the northwest of the huge Apollo impact basin. Walker lies equidistant between Plummer crater to the east and Rumford crater to the west-southwest.
This crater is roughly circular, with an outer rim that has been slightly worn due to minor impacts. The northwestern rim in particular has merged with a smaller crater, and another impact lies on the interior floor along the west-northwestern inner wall.

By convention these features are identified on lunar maps by placing the letter on the side of the crater mid-point that is closest to Walker crater.
