DescriptionAbout 16 miles west of San Andreas via SR 12, Paloma Road, Watertown Road and Campo Seco-Chile Camp Road is Campo Seco, a 19th-century mining settlement. Dubbed Campo Seco (dry camp) by prospectors, the region produced some gold, but the real treasure was copper. The Penn Copper Co. supplied the Union Army with the metal during the Civil War. Although Campo Seco has a post office, it's officially designated a ghost town. There is one remaining landmark of note, though—what is believed to be California's largest cork tree, planted in 1858.
