The Rock River and Pecatonica River converge south of the Wisconsin-Illinois state line, anchoring a corridor of established river towns and residential growth. This 2021 survey details the dense suburban and industrial layouts of Beloit, South Beloit, and Rockton, where historical landmarks like the Rockton Township Cemetery sit alongside modern developments. The map tracks the shift from the manufacturing centers of the north to the expanding residential neighborhoods of Roscoe and Machesney Park further downstream.
