About this map

Gold Country mining history and remote river canyons define this 1948 survey of the California foothills. The settlement of Rail Road Flat and nearby Independence anchor a landscape carved by the North Fork Mokelumne River and its numerous tributaries. High points like Alabama Hill overlook a network of gulches named for early prospectors and settlers, including Whiskey Slide Gulch and Humbug Gulch.

Evidence of the region's hard-rock mining legacy is scattered throughout the terrain, with specific sites such as the Etna Mine, Wolverine Mine, and Jeff Davis Mine noted. The presence of Ponderosa Way and the Victory Dude Ranch suggests the area's transition into mid-century recreation and forestry. Smaller settlements like Glencoe and a local Cem (cemetery) provide essential points for genealogists tracing family histories in the rugged boundary lands of Amador and Calaveras counties.
