About this map

Tuolumne Indian Rancheria and the settlement of Tuolumne anchor this post-war landscape, where the Sierra RR winds through the hills to serve a region defined by its timber and mining heritage. The mapping reveals a complex network of resource extraction and early mountain infrastructure, including the State Fish Hatchery near The Basin and the Arastraville Sch serving the northern settlements.

Hard-rock mining remains a visible legacy across the terrain, with family-named operations like the Hattie Ester Mine, Spring Gulch Mine, and Jigger Bill Brothers Mine scattered along the drainages of Hunter Creek. The presence of numerous named homesteads, such as Ralph Ranch and Ingalls Ranch, alongside a Cem and the Riverside Station, provides critical details for genealogists tracing the mid-century population of the foothills and the Stanislaus National Forest borderlands.
