The Mother Lode gold belt carries the most productive and best-known mining districts in California's gold country. Although the entire foothill region of the Sierra Nevada is sometimes loosely termed the "Mother Lode Country," technically the Mother Lode is a 120-mile-Iong system of linked or en echelon gold-quartz veins and mineralized schist and greenstone that extends from the town of Mariposa, north and
northwest to northern E1 Dorado County.


The most productive portion of the Mother Lode has been the 1 mile segment between Plymouth and Jackson in Amador County. Other major sources of gold in the Mother Lode have been the Angels Camp, Bagby, Carson Hill, Coulterville, Georgetown, Greenwood, Jacksonville, Jamestown, Kelsey, Mount Bullion, Nashville, and Placerville districts.
