St. John Mine

St. John Mine, originally a natural cave, was worked by Native Americans before Wisconsin's 1827 "Lead Rush." Willis St. John, first Non-American to work the mine which now bears his name, made a small fortune here between 1828 and 1848. Learn how miners toiled 12-hour days, marvel at stalactites and wonder how men could work in such confinement.
