alt Hacker NewsI live near Galena, IL, which also part of a tri-state (IL, IA, WI) which itself is part of the Driftless Area. Our mineral and mining boom started in the 1820s and I think was much reduced by the 1860s. Mining was so important in our area that Galena's post office also served as a port of entry for migrant workers from Europe, and Wisconsin's first capital was nearby in the mining town of Belmont. The Mississippi River made the mining boom possible.
