1959 Map of San Jacinto

About this map

Jefferson Proving Ground dominates the landscape of this southern Indiana region, marking a significant military footprint across the intersection of Jennings, Ripley, and Jefferson counties. Established as a U S Military Reservation, the area is defined by an extensive network of specialized transit routes, including Recovery Road, Military Reservation Road, and Eye Road. These pathways cut across the natural drainage systems of Graham Creek and Big Lancaster Creek, which meander through the central and southern portions of the survey.
