NOTE: There is no file for this district in the USGS MRDS database.

Location: Camptonville, in northeast Yuba County and western Sierra County, adjoins the Pike district on the E. Only a portion of this district, which is centered in Yuba County, is within Sierra County.

History: Rich gold discoveries were made here in 1850-1851. The town was named in 1854 for Robert Campton, the local blacksmith. The Pelton wheel, long used in mining machinery and electric generators, was invented here by Lester Pelton. The old town is now a tourist attraction.

Geology: A number of moderate-sized deposits of Tertiary channel gravel were mined by hydraulicking. These include the deposits at Young's Hill, Weed's Point, and Galena Hill. They are part of the Tertiary Yuba River that extended SW from Indian Hill to this district and then to North San Juan. Bedrock is amphibolite, slate, greenstone, and granodiorite.
