Complex Crater

Image Source:

Craters with stepped terraces on the interior wall, a flat floor, and a single peak or group of peaks in the center. The interior wall terraces, which form due to landslides, result in a shallower overall inclination of the wall than in simple craters. The exterior rims are similar in appearance to simple craters. The photograph shows King Crater on the far side of the Moon, a typical lunar complex crater, which is 93 km in diameter and ~5 km deep. The central peaks are ~2 km high.
