USGS Topo · Published 1972About this map
The Mackinaw River winds through this Central Illinois landscape, carving a valley defined by numerous gravel pits and complex hydrology. The village of Mackinaw sits as the primary hub, where the Penn Central tracks intersect the local road network. Notably, the map records the Oak Knoll Sanatorium situated just north of the village, a specialized medical facility that once served the region. Nearby, the smaller settlement of Lilly and the rail stop at Sargent reflect the rural development patterns of the mid-20th century.
