✨️ Empire Mine in Grass Valley, California, is one of the oldest, richest, and most legendary gold mines in the state. From 1850 to 1956, it produced over 5.8 million ounces of pure gold, fueling California’s Gold Rush dreams. Today, it’s a stunning state historic park, where you can wander through underground mine tunnels, elegant gardens, and the estate of the mine’s wealthy owners. #empiremine #empireminestatepark #goldmining #goldmines #california #goldrush | California Vlog
