The West Nishnabotna River and the East Branch West Nishnabotna River converge in this corner of Shelby County, creating a fertile valley dominated by agricultural grid-lines and rural landmarks. The unincorporated community of Corley sits at the intersection of Street F58 and the river valley, while the town of Avoca anchors the southern boundary at the Pottawattamie County line. This 2018 survey detail provides a modern inventory of the area's spiritual and civic geography, marking several local burial grounds including Fairview Township Cem, Lee Cem, and Jacobson Cem.
