USGS Topo · Published 1956About this map
The Illinois River serves as the central artery for this mid-century landscape, carving a wide valley between Pike, Greene, and Calhoun counties. Settled communities like Pearl and Hillview are situated along the Chicago and Alton railroad line, while the river's eastern banks are characterized by extensive drainage infrastructure, including the Fairbanks Pumping Sta and several others designed to manage the fertile bottomlands of Bluffdale and Walkerville.
