Walter (80 miles) is a large, flat floor crater with high terraced walls that exceed 2 miles. The floor is mainly smooth, except on the northeastern floor where there are hills and a grouping of five craters, each about the same size. Although this formation is located in the extensively cratered highlands you should have no problem locating it at first quarter.

Aliacensis (48 miles) is a fine crater over 2 miles deep with terraced walls. The flat floor has a small, off center peak.

Werner (42 miles) is a circular crater, similar to Aliacensis, but a little smaller. Its terraced walls rise 2 miles above the floor. There is a small peak that is off center and the rough floor has small hills.
