About this map

Diagonal serves as the primary hub of this rural Ringgold County landscape, situated where the Chicago And North Western railroad line cuts through the countryside. The geography is defined by the winding course of the Grand River, which is joined by numerous tributaries including Squaw Creek, Indian Creek, and West Plum Creek. The town of Knowlton appears just north of Diagonal, highlighting a period of close-knit rail-oriented settlements.

Genealogists will find several burial sites scattered across the townships of Jefferson, Lincoln, and Washington, such as Keller Cem, Diagonal Cem, and the Bohemian Cem. The map also captures local recreational and industrial landmarks, from the Kckesh County Recreation Area Campground near the river to a Gravel Pit along the northern rail line, illustrating the mix of natural resource extraction and community space in southern Iowa during the early 1980s.
