The South Fork Maquoketa River and its primary tributaries, including Silver Creek, Bear Creek, and Cline Creek, define the landscape of eastern Delaware County during the mid-1960s. The settlement of Hopkinton sits along the western edge, while Sand Springs remains a distinct community to the east, connected by the winding route of the Chicago Milwaukee St Paul and Pacific railroad.
