About this map

Monocline Ridge and the Tumey Hills dominate this mid-century landscape in the western San Joaquin Valley, where the transition from rugged uplands to the valley floor is marked by significant industrial infrastructure. The area’s water and energy economy is evident through the presence of the Chaney Pumping Station, an Oil Tank, and a network of agricultural thoroughfares including Manning Avenue and Floral Ave.

Topography recorded in the mid-1950s shows several small-scale mining and ranching operations, such as Freeman Ranch and multiple Prospect sites along Tumey Gulch. The map also captures specialized rural developments like a Landing Strip and a Reservoir, while noting Water Tanks (Abandoned) near the Fresno and San Benito County line, reflecting a changing footprint of habitation and utility on the slopes of Ciervo Hill.
