1912 Map of Mariposa

About this map

The Sierra Nevada foothills and the edge of Yosemite National Park define this landscape during the early twentieth century. Gold mining and timber operations are evident through features like the Lone Tree Mine, Texas Flat Mine, and the Marble Quarry near Knowles. The map captures an era when specialized schools, such as the Iron Mtn School and Chowchilla School, served remote ranching and mining families. Significant natural landmarks like the Mariposa Grove Big Trees stand alongside human developments including a Powerhouse and the Old Fort Miller site. The complex network of the Chowchilla River and Fresno River provided the water necessary for the region's flumes and settlements. Local commerce is anchored by centers like Coarse Gold and Raymond, while higher elevations include Fresno Dome and numerous summer grazing meadows.
