from Biela covers the northwestern part of the interior. Despite a certain degree of wear, the rim of Biela remains relatively well-defined, especially in the southeast.
The interior floor is flat and not marked by any craterlets of note. There is a central peak formation of three ridges located just to the northeast of the midpoint.
