1971 Map of Dunlap SW

About this map

The Boyer River corridor dominates this 1971 topographic landscape, serving as a primary conduit for both water and rail transportation through Harrison County. The Illinois Central Gulf and Chicago North Western rail line parallels the river valley, marking a clear industrial and logistical spine that contrasts with the surrounding township divisions. These divisions, including Willow, Boyer, Lincoln, and Douglas, are defined by a network of drainage systems including Willow Creek and Picayune Creek. Local history is anchored by the Valley View Cem in the northeast, while smaller landmarks like North Picayune Cr and Mud Creek illustrate the dissected terrain typical of western Iowa's loess hills region.
