1978 Map of Irwin

About this map

Irwin sits at the heart of this Shelby County landscape, where the Chicago and North Western railroad parallels the course of the West Nishnabotna River. The settlement pattern reflects the mid-century agricultural organization of western Iowa, with the map recording the precise locations of a municipal Water Tank and a Well crucial to local infrastructure. Outside of the town center, the terrain is defined by the branching waters of Elk Creek and Long Branch, which carve through the townships of Greeley and Jefferson. Genealogists will find the Oak Hill Cem south of the main settlement, while the smaller community of Botna appears near the northern boundary, highlighting the historical corridor of rail-to-river transport that shaped this part of the state.
