1985 Map of Humbug Mountain

USGS Topo · Published 1985

About this map

Mining operations dominate the landscape of the Humbug Mountain and Pinto Mountains area in this mid-1980s topographical study. The map documents a significant history of extraction across the San Bernardino and Riverside county line, where complex topography is punctuated by numerous named claims. Researchers can find specific locations such as the Imperial Mine, Gypsy Mine, and Golden Eagle Mine. Traces of previous habitation and industry are evident at the Ruins Old Mill Site and scattered Ruins near the Joel Mine. The settlements of Old Dale and New Dale anchor the northern portion of the quadrangle, reflecting the shifting centers of local activity. A Radio Facility in the northeast corner highlights the modernization of this arid mountain terrain during the latter half of the twentieth century.
