The Reed Gold Mine was founded where the first nugget of gold was found in the United States. In 1799, a young boy found a shiny rock while playing in the river, and the family used it as a doorstop. Three years later, they sold it for a small price. However, John Reed soon understood his mistake, and he established the mine with partners. It worked and produced gold until 1912.
Some of the mine tunnels have been restored, alongside a visitor center with gold and gold mining displays. After visiting the museum you can take a paper guide for a self-guided tour, including an underground walk, and It's a great visit, and I highly recommend it.
Admission is free.
