The Illinois River corridor near Pekin serves as a major industrial and geographic divide, separating Peoria and Tazewell counties. The landscape is dominated by the massive Powerton Cooling Lake and the adjacent industrial site at Powerton, while the surrounding terrain is dotted with numerous small settlements like Mapleton, Hollis, and Schaeferville. The river valley itself contains significant natural and man-made features including Pekin Lake, Pond Lily Lake, and Coopers Island.
