. The rim perimeter is somewhat irregular, and has been disturbed in several locations by subsequent impacts. There are small craters along the eastern and northwestern rim, and an asymmetrical formation along the southern inner wall. The northern rim is uneven, with a diagonal gouge running to the southeast. Much of the interior floor is level and nearly featureless, with a small central peak offset to the north-northeast of the midpoint.

Satellite craters

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Santbech.
