The outer rim of Gibbs crater is not quite circular, and an outward bulge to the north gives it an onion-like profile. The southeastern wall is slightly straightened and there is a low break in the rim at the southern and northern ends. In other respects, however, the rim is only slightly eroded. The interior floor is nearly level in the southwestern half, with irregular ridges to the northeast. There is a small craterlet to the northwest of the mid-point.
A recent small impact along the northeastern rim has produced a small ray system that forms a skirt of higher albedo material across this part of the rim. Faint traces from these rays cover the interior floor of Gibbs crater.
Satellite craters
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 Gibbs crater.
