Before California's Gold Rush, there was Michigan's Copper Rush. From the 1840s to the 1920s, the Keweenaw Peninsula in Michigan's Upper Peninsula supplied over 90% of the world's copper—America's first true mining boom. But this story isn't about striking it rich. The Adventure Mine pulled 11 million pounds of pure copper from the earth and made exactly zero dollars in profit. Why? The copper was too pure. Pure copper is too soft to drill, too heavy to lift, and ironically harder to extract than ore. Shane takes you 300 feet underground into the Adventure Mine, where miners worked 10-hour shifts by candlelight for a dollar a day, and where an underground bike race now navigates the same treacherous tunnels. This is the forgotten story of the boom that ended in ghost towns, abandoned by the companies who scraped even the train tracks when they left.
