1959 Map of San Jacinto

About this map

Jefferson Proving Ground dominates this landscape at the intersection of Jennings, Ripley, and Jefferson counties. This expansive U S Military Reservation is defined by a rigid network of interior transit ways including Recovery Road, Center Road, and Military Road. Outside the restricted federal boundaries, the settlement of San Jacinto sits near the winding course of Big Graham Creek. The terrain is characterized by the deep incisions of waterways like Little Graham Creek and Horse and Poplar Branch, which contrast with the orderly grid of the military facility. Genealogists may find interest in the location of Bethel Cem, situated along the western edge of the reservation boundary near Graham Creek. The map documents the mid-century footprint of this massive ordnance testing facility before its eventual decommissioning.
