Cerro Gordo and Milmine anchor this 1980s landscape at the border of Macon and Piatt Counties, where the Norfolk and Western railway cuts a straight path across the central Illinois prairie. To the north, the Sangamon River meanders through a wooded corridor, creating a distinct natural break in the otherwise systematic grid of the Willow Branch and Cerro Gordo townships. This riverine landscape is home to Robert Allerton Park, a significant cultural and natural landmark for the University of Illinois.
