The rim of this crater is worn by impact erosion, particularly along the eastern side where a pair of small crater lie along the edge. The rim and inner wall are more prominent to the west and north, while it forms only a shallow ridge to the southeast. The interior floor is marked by a cluster of small craters in the northeastern part, and tiny craterlets scattered across the remainder.
