The East Nishnabotna River corridor defines the eastern edge of this agricultural landscape in Audubon County. The town of Exira sits along the river's eastern bank, marked by its local Po and High Sch, while the smaller settlement of Brayton is positioned further south where the river bends. This early 1980s record illustrates a rural economy rooted in both the land and extraction, featuring a Quarry near Oakfield Cem and a Sandpit located near the southern boundary line between Audubon Co Cass Co. Genealogists will find several burial grounds across the townships of Sharon, Hamlin, and Oakfield, including St Johns Cem and Oak Hill Cem. The terrain is characterized by the branching drainages of Elkhorn Creek and Sifford Creek, which carve through the Iowa prairie upland.
