1967 Map of Black Star Canyon

About this map

Santiago Reservoir and its surrounding canyons reveal a landscape of deep resource extraction and mid-century technical development along the Orange and Riverside county line. During the 1960s, this portion of the Cleveland National Forest supported various industrial operations, including the Santiago Coal Mine and Black Star Coal Mine, alongside the unique Rocket Fuel Test Site tucked into Gypsum Canyon. The map details the transition from the lowlands of Irvine Park to the high elevations of the Santiago Mountains, culminating at Sierra Peak. Long-standing local landmarks like Beeks Place and Hidden Ranch are situated along the Main Divide Road, providing critical reference points for genealogists and local historians tracking early settlement and ranching boundaries in these canyons.
