It's no secret that the Gold Rush made California what it is today. With this history in mind, the State of California has overseen the preservation of Empire Mine for decades. During its long life as an active mine (1850-1956) this mine was one of the biggest, deepest, and richest gold mines in California. Take some time to explore the area and a small portion of the 367(!) miles of underground tunnels.
