About this map

Diagonal and the neighboring settlement of Knowlton anchor this Ringgold County landscape, situated where the Grand River and several tributary creeks like Wolf Creek and Plum Creek carve through the Iowa countryside. The town of Diagonal is characterized by its organized grid and the Diagonal Post Office, serving as a local hub for the surrounding agricultural community. To the north, the Sun Valley Lake Dam contains the waters of Sun Valley Lake, a significant local water feature that contrasts with the traditional farm-to-market road network including Co RD j23.

Family history and local heritage are well-represented by a high density of burial grounds, notably the evocatively named Dead Man's Curve Cemetery and the Bohemian Cemetery. These sites, along with Quinn Cemetery, Knowlton Cemetery, and Bethel Cemetery, provide fixed points for genealogical research across the townships. The drainage patterns of Crooked Creek and Indian Creek further illustrate the topographical variety of this Midwestern interior at the start of the twenty-first century.
