The settlement of Thor serves as the central hub of this agricultural landscape along the border of Humboldt Co and Webster Co. The map reveals a highly engineered water management system essential for local farming, featuring numerous man-made waterways like Drainage Ditch Number 46 and Ditch Number 25. These channels supplement natural drainage from Beaver Cr and Soldier Cr, illustrating the intensive land use in this part of north-central Iowa.
