1948 Map of Sonora

About this map

The Sierra Nevada foothills south of Sonora reveal a landscape defined by the legacies of the California Gold Rush and the infrastructure of the early 20th century. During the late 1940s, the Sierra Railroad and the massive Hetch Hetchy Aqueduct cross the terrain, illustrating the region's role in the state's water and transportation networks. Historic mining activity is documented through numerous named claims and shafts, including the Eagle-Shawmut Mine, Harvard Mine, and the Golden Rule Mine. Cultural landmarks like the Mark Twain Cabin near Jackass Hill and the settlement at Chinese Camp speak to the diverse social history of Tuolumne County. Small communities such as Soulsbyville, Jamestown, and Standard appear alongside rural family landmarks like the McNutt Ranch and Barron Ranch, providing a window into local genealogy and land use before mid-century modernization.
