1985 Map of Sheep Hole Mountains

USGS Topo · Published 1985

About this map

Mining operations and arid basins dominate this mid-1980s landscape at the boundary of San Bernardino and Riverside counties. The Sheep Hole Mountains and Pinto Mountains are pockmarked with dozens of prospect sites including the Virginia Dale Mine, Iron Age Mine, and War Eagle Mine, reflecting a century of mineral extraction. Settlement is sparse, restricted to rail-side outposts like Chubbuck and Milligan along the Atchison Topeka and Santa Fe line, or the isolated location of Old Dale.
