About this map

Mokelumne Hill stands as the historic focal point of this Mother Lode landscape, situated just south of the Mokelumne River as it divides Amador and Calaveras Counties. The 1948 survey reflects a transitional era for the region, balancing its gold-mining heritage with newer infrastructure. Large-scale water and power management is evident at the Electra Powerhouse and Lake Tabeaud, while the Mother Lode Airport signals the mid-century modernization of transport.

Tracing the complex terrain of the Sierra foothills, the map captures a network of small settlements like Pine Grove, Glencoe, and Railroad Flat. It also identifies former town sites such as Butte City and Rich Gulch, providing essential data for genealogists tracking family-named locations like the Helbing Ranch or Lombardi Ranch. Industrial features range from the Belden Mine to the Lumber Road, illustrating how timber and mining continued to shape the local economy.
