About this map

Tuttle Creek Lake dominates the southern reaches of this landscape, its expansive waters and the adjacent Tuttle Creek State Wildlife Area reshaping the original river valleys. The terrain is marked by significant historical waypoints, most notably Alcove Spring, a vital stop on the overland trails. The map reveals a dense network of late-20th-century townships such as Marysville, Blue Rapids, and Seneca, each serving as a hub for the surrounding agricultural grid.

The hydrology of the region is defined by the Little Blue River and the Black Vermillion River, which wind through a mosaic of townships like Guittard and Murray. For researchers, the map provides a precise look at local infrastructure before further modern consolidation, documenting everything from the Marysville Municipal Airport and rural Landing Strip locations to distinctive geographical markers like Twin Mounds and Indian Mound. Small communities such as St Bridget, Baileyville, and Hollenberg remain clearly delineated, preserving the mid-1980s settlement pattern across Marshall and Nemaha counties.
