The county seat of Carthage anchors the eastern edge of this mid-1970s survey, showing a well-developed grid featuring the Courthouse, City Hall, and Robert Morris Jr College. The surrounding landscape of Rock Creek Prairie is defined by a dense network of transportation and rural community hubs. Two major rail lines, the Toledo Peoria and Western and the Norfolk and Western, intersect in the region, supporting small settlements like Ferris and McCall.
