The Rock River dominates this Illinois-Wisconsin borderlands survey, winding southward from the industrial center of South Beloit through the river towns of Rockton and Roscoe. The landscape reflects a mix of heavy industry and recreation, where extensive Gravel Pits and quarries sit adjacent to large conservation areas like Macktown Forest Preserve and Hononegah Forest Preserve. The convergence of the Pecatonica River with the Rock River near Rockton creates a complex hydrologic network of creeks including Raccoon Creek and Dry Creek.
