About this map

Golden Queen Mine and the Bobtail Mines anchor the northern slopes of Soledad Mountain, highlighting an active industrial landscape of extraction in this part of Kern County. The map details a complex network of mining operations, from the Tropico Shaft near Tropico Hill to various Quarries, Borrow Pits, and a Claypit. These industrial features sit in stark contrast to the small residential pockets like Hidden Valley and the Trailer Park to the west.

The eastern edge of the quadrangle is defined by the Southern Pacific railroad and the Sierra Highway, which serve as the primary transport corridor for the region. This infrastructure borders the sprawling Edwards Air Force Base Flight Test Center, signaling the area's mid-century shift toward military aerospace testing. Local rail stops and small settlements like Actis, Ansel, and Fleta dot the tracks, providing a detailed look at the rural logistics of the early 1970s.
