1912 Map of Mariposa

About this map

Mariposa and the surrounding Sierra Nevada foothills appear here during a period of intense resource extraction and early conservation. The landscape is heavily marked by the region's mining heritage, with sites such as the Buchanan Mine, Enterprise Mine, and the Trabuco Mines dotting the drainages of the Chowchilla River and Fresno River. The map highlights the early boundaries of Mariposa Grove Big Trees in Yosemite National Park, where the Summerdale post office and Happy Camp supported early tourism. Settlement patterns show a mix of established mining camps like Coarse Gold and Grub Gulch, and indigenous presence at the Picayune Indian Settlement. Transport is anchored by the Southern Pacific Railroad in the west, while high-altitude meadows such as Boggy Meadows and Kelty Meadow characterize the eastern wilderness before the full expansion of modern reservoirs.
