Union Center and the surrounding farmland of Plymouth County are defined by a strict grid of county roads and the winding paths of several regional waterways. This agricultural landscape is drained by Mud Creek, which flows south through the center of the sheet, while the headwaters of Johns Creek and the multiple forks of Dry Branch carve subtle relief into the terrain. The map documents the persistent rural footprint of the area, anchored by the settlement at O'Leary and two significant burial grounds for local genealogy: Union Cemetery and Saint Josephs Catholic Cemetery. These locations, positioned along routes like Nature Ave and Pioneer Ave, represent the community's historical centers in an era where the landscape is almost entirely dedicated to large-scale production.
