The crater rim has not been severely worn by crater impacts, and the inner wall possesses wide terraces. These structures have been somewhat smoothed by landslips and erosion, most likely induced by seismic activity. An influx of material has entered across the northern rim, flowing down toward the base. The crater floor is relatively smooth, with only minor hills and impact craters. In the middle is a complex central peak surrounded by lesser mounts. The main peak rises to a height of 2.0 kilometers above the surrounding floor.
