1953 Map of Black Rock Spring

About this map

The Yakima Firing Center Military Reservation dominates the landscape of Yakima County in the early 1950s, a period when this arid terrain was repurposed for defense operations. Across the northern half of the map, the high elevations of Yakima Ridge descend into Black Rock Valley, where the Hanford Road cuts through the desert floor. The map records several notable family outposts of the era, including the Coffin Ranch near Cold Creek and the MacKintosh-Douglas Ranch located further south. Critical water sources in this dry climate are clearly documented, from Nelson Spring on the ridge to Black Rock Spring in the valley center. The presence of a Gravel Pit and the rugged topography of Firewater Canyon suggest a landscape defined by both industrial utility and natural isolation during the mid-century.
