Clark is a lunar crater that lies in the southern hemisphere of the Moon's far side. It is located midway between the larger Van der Waals walled plain to the south and the similar-sized Pizzetti crater to the north. This crater 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.
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 Clark crater.
