1956 Map of Joaquin Rocks

USGS Topo · Published 1958

About this map

Joaquin Rocks and the craggy peaks of Joaquin Ridge anchor the southern portion of this mid-century Fresno County landscape. The terrain transitions from the high elevations of Black Mtn and the Ciervo Hills down into the intensive agricultural and industrial zones of the valley floor. To the south, the Coalinga Oil Field and the East Coalinga Extension Oil Field show the region's energy footprint, while the northern plains are dominated by large-scale agricultural operations. Named holdings such as Giffen Cantua Ranch, Lillis Ranch, and Tres Picos Farms illustrate the pattern of land ownership and labor during this era. The map also records several labor camps and localized features like The Clearing and Skunk Hollow, providing a detailed look at the rural infrastructure supporting the valley's cattle and petroleum economies.
