Park Information

Lead has been big business in the eastern Ozarks since about 1720. Come explore its history – and see the processing plant of the former St. Joe Lead Co. – in the heart of the Old Lead Belt at Missouri Mines State Historic Site. The mine’s former powerhouse has been turned into a museum that interprets the area’s lead mining history, displays actual machinery from the mines and houses one of the Midwest's finest mineral collections.
