Williams is the remnant of a lunar crater that lies to the south of the prominent Hercules crater, in the northeastern part of the Moon. The southern rim borders the Lacus Somniorum, a small lunar mare that extends to the south and west. To the southwest is the sharp-rimmed Grove crater.

Little remains of the original crater, besides a low curving ridge. The rim has been nearly destroyed along the northwest face, leaving only a few ridges in the surface. The remainder forms an irregular horseshoe, with the western part attached to a series of ridges leading to the west. The interior floor has been resurfaced by basaltic-lava, forming a flat, nearly featureless surface that is marked only by a pair of tiny craters near the northeast rim.

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 Williams crater.
