The rim of this formation has been eroded, worn down, and reshaped by a history of impacts, leaving an irregular, indented perimeter surrounding the crater floor. The interior of the formation has been resurfaced by basalticlava, leaving a level, nearly featureless surface that contains no impacts of note. While the interior surface has a low albedo and appears dark, it has been coated by ray material which has produced lighter patches to the southwest and northeast.
Prior to formal naming in 1970 by the IAU,[1] the crater was known as Crater 436.[2]
