About 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.

Water management and recreation are evident in the presence of Maraldo Lake, Spin Lake, and Posey Ridge Lakes. Local family history is preserved through several rural burial grounds, including Stumbaugh Cem, Hardscrabble Cem, and Bergen Cem. The terrain transitions from the agricultural plateaus of Deer Creek in the north to the lowlands of the Little Mackinaw River in the south, illustrating the drainage systems that shaped Tazewell County's geography.
