About this map

Portsmouth serves as the primary hub of this Iowa landscape, situated along the Ia 44 corridor. The town's local history is anchored by Saint Marys Cem, which overlooks the surrounding agricultural grid. The terrain is defined by a dense network of drainage, where Pigeon Cr and Little Pigeon Cr carve through the rolling sections of the county line between Harrison and Shelby Counties.

A strictly organized system of section-line roads, including Co Rd F32 and Co Rd L66, illustrates the persistent township and range structure of the American Midwest. The southern portion of the map is marked by the headwaters of Spring Cr and Mosquito Cr, which flow through a rural environment where legacy names like Troy Trl suggest the early routes and paths used by settlers to navigate these western Iowa drainages.
