Union Center and the small settlement of O'Leary anchor this agricultural landscape in Plymouth County, reflecting the deep-rooted grid system of Iowa's farmland. The territory is defined by a rhythmic network of section roads like Nature Ave and Polk Ave, which carve the prairie into productive plots. This 2013 survey illustrates how modern drainage and topography interact, with Mud Cr and its various tributaries, such as Dry Br, winding through the terrain. The presence of O'Brien Prairie suggests a preserved or recognized natural feature amidst the vast network of county routes, including c44 and c60. For those researching local family farms or township geography, the map provides precise locations for these intersections and watercourses, including Big Whisky Cr and Johns Cr on the eastern edge.
