About this map

The borderlands of northern Missouri and southern Iowa center on Lake Thunderhead, a prominent reservoir that defines the local landscape. This modern survey illustrates the geographic intersection of Wayne County, Appanoose County, and Putnam County, where the settlement of Genoa stands as a focal point in the northwest. The terrain is deeply etched by the winding course of N Blackbird Cr and its tributaries, including S Cr, which drain the undulating hills into the lake.

Institutional landmarks and local infrastructure are well-documented, including the Unionville Municipal Airport and historical burial sites such as Union Cem and Livingston Cem. A network of rural routes, including Cemetary Rd and Lupton Cemetery Rd, provides access to these sites. The map clearly delineates the Iowa Missouri state line, reflecting the organized grid of the Public Land Survey System that continues to shape property and road boundaries in this agricultural region.
