Old mining structures at Plumas-Eureka State Park in Plumas County. Sometimes called the best-kept secret within the California State Park System, Plumas-Eureka State Park is located at the foot of Eureka Peak, (originally called Gold Mountain) which produced some $25 million in gold from hard-rock mining during the late 1800s.

The park features an indoor-outdoor museum of early gold mining equipment and relics, a complete blacksmith shop, a partially restored stamp mill, and a restored miner's home.

The park surrounds the historic former mining community of Johnsville. Photo by Carol Highsmith, 2012.
