Wisconsin’s ancient copper mines are among the oldest known mining operations in North America, with the earliest evidence of human activity dating back about 9,500 years. That means Native Americans were extracting copper here more than 7,000 years before the pyramids were built, and the practice continued across a very long period that included 4,000–1,200 B.C.E.
