Copperopolis, Historical mining site in Calaveras County, California, US.
Copperopolis is a rural settlement in Calaveras County that retains various structures from its mining past scattered across the countryside. Old shafts, machinery parts, and mining buildings can still be seen throughout the area today.
The settlement was established in 1860 when miners discovered copper deposits and started extracting ore from the land. Growth accelerated during the Civil War period when copper became highly sought after for military production.
The four buildings listed on the National Register of Historic Places include the Copperopolis Armory, Congregational Church, Honigsberger Store, and Reed's Store.
The site can be explored on foot and is generally open for visitors, though sturdy footwear is advisable due to uneven ground and old mining hazards. Bring water and a hat as shade is limited in this rural area.
The mines produced over 72 million pounds of copper valued at more than $12 million before their closure in 1946, marking the end of major mining operations.
