1937 Map of Lacon

About this map

The Illinois River serves as the central artery for this 1930s survey, carving a wide valley filled with backwater lakes and sloughs. Settled river towns like Henry and Lacon anchor the banks, connected by bridges that cross complex water systems including Senachwine Lake, Sawmill Lake, and Billsbach Lake. The landscape transition from the river bottom to the surrounding prairie is marked by a dense network of early 20th-century rural infrastructure.
