is located in the western part of Poczobutt's interior. Little of the outer rim of this crater remains intact, and what survives is worn and eroded. The outer rim now forms an irregular ring of peaks, broken in several locations by small craters. The most intact portion of the rim is a small arc along the eastern side. Likewise much of the interior floor is irregular due to overlying impacts or their ejecta. However, there is a level plain in the eastern half of the interior that is almost flat and featureless. This region is marked only by a few low ridges around the fringes and some tiny craterlets. A small crater at the southern edge of this plain has a flooded, featureless interior. Most of the crater formations associated with Poczobutt are almost as eroded as the main crater. However Smoluchowski H, along the outer rim to the northeast, has a sharp, well-defined rim, some

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