The Old Indian Treaty Boundary slices through this section of Auglaize County, marking a significant historical line in the settlement of western Ohio. The landscape is defined by the industrial and agricultural rhythm of the early 1960s, centered on the villages of Uniopolis and St Johns. Transportation dominates the layout, with the Detroit Toledo and Ironton RR running north-south through Slater and Gutman, while the Penn Central line traverses the southern reaches near Geyer.
