1971 Map of Pleasant Plains

Genealogists and local historians will find several landmark sites, including the Island Grove Ch and a rural Cem near Berlin. The topography is shaped by the drainage systems of Richland Creek, Prairie Creek, and Spring Creek, which reveal the underlying prairie structure. Noteworthy infrastructure of the era includes a local Waterworks, a Radio Tower, and a modest Landing Strip, providing a clear look at the rural utility and transportation networks of central Illinois at this time.
