The settlement of Thor serves as the central hub of this agricultural landscape in the late 1970s, situated along the Chicago and North Western railroad line. The map reveals a highly engineered water management system essential for local farming, featuring an extensive network of drainage channels such as Ditch No 46, Ditch No 3, and Ditch No 9. These man-made features work in tandem with natural waterways like Beaver Creek and Soldier Creek to drain the fertile plains.
