1971 Map of Unityville

About this map

Unityville serves as the central hub of this agricultural landscape in the early 1970s, situated near the intersection of McCook and Miner counties. The township of Sun Prairie dominates the central portion of the map, where the Chicago and North Western railroad cuts a diagonal line across the prairie. The drainage of the West Fork Vermillion River and the Little Vermillion River creates a meandering network of riparian corridors through the otherwise orderly grid of section lines and township boundaries. Local social centers are anchored by rural institutions such as the Sun Prairie Ch and Evangelical Ch. The landscape is dotted with several Gravel Pits, indicating local industrial activity tied to the regions' geology, while small family or community markers like Olsen Cem provide critical points of interest for genealogists tracing South Dakota roots.
