1970 Map of Seneca
USGS Topo · Published 1972About this map
The Illinois River corridor near Seneca is defined by a dense intersection of historical industrial and transport infrastructure during the 1970s. The landscape reflects the transition from early commerce to modern industry, with the Illinois and Michigan Canal (Abandoned) running parallel to the active Chicago Rock Island and Pacific railroad lines. Significant river features like Grist Island, Barry Island, and McNellis Bayou punctuate the waterway, while the local economy is anchored by a large Chemical Plant and several Gravel Pits.
