. Clark has a narrow inner wall, and thus a wide interior floor. The rim is roughly circular, but eroded in places. A small crater lies across the southern rim, and a tiny pair are located along the northeastern crest. There is a slight outward bulge along the wall along the west-southwestern side. The crater floor is marked by a number of tiny craterlets but otherwise relatively featureless, having no central peak.
