2018 Map of Diagonal
USGS Topo · Published 2018About this map
Diagonal and the neighboring settlement of Knowlton anchor this Ringgold County landscape, where the Grand River and its various tributaries carve a complex drainage pattern through the Iowa countryside. The area is notably dense with small rural burial grounds, including the curiously named Dead Man's Curve Cem and the heritage-rich Bohemian Cem. These sites, along with Quinn Cem, Knowlton Cem, and Bethel Cem, offer significant geographic markers for genealogical research into the families who settled this region of the state.
