1953 Map of Black Rock Spring

About this map

Yakima Military Reservation occupies a massive portion of this mid-century landscape, highlighting the area's transition into a significant defense and training corridor. The rugged topography is defined by the high crests of Yakima Ridge and the volcanic prominence of Hog Ranch Buttes, which separate the agricultural potential of Moxee Valley and Black Rock Valley. Despite the military presence, evidence of an earlier ranching economy remains through named homesteads such as Holmes Ranch, Bernhardt Ranch, and Coffin Ranch. Water is the critical resource here, marked by remote sites like Black Rock Spring and Nelson Springs. Cultural landmarks like the Plant Quarantine Station and an Abandoned Reservoir near Rattlesnake Hills suggest the evolving land management and irrigation efforts typical of central Washington during this era.
