2018 Map of Union Center

About this map

Union Center and the neighboring community of O'Leary anchor this agricultural landscape in Plymouth County, which maintains a grid-like settlement pattern established during the era of frontier land surveys. The terrain is defined by the drainage systems of Mud Cr and Dry Br, which carve distinct valleys through the surrounding fields. Local history and genealogy are centered on the Union Cem and Saint Josephs Catholic Cem, which represent the spiritual and ancestral hubs of this rural township. A dense network of roads, including Co Rd C44 and north-south corridors like Nature Ave and Polk Ave, illustrates the persistence of the section-line road system that has facilitated Iowa farming for generations. Small waterways like Big Whiskey Cr and Johns Cr further define the local hydrology, providing natural landmarks within the highly structured township and range system.
