Galena has been produced from the Upper Mississippi Valley zinc-lead district in Wisconsin since the seventeenth century. Some mines started by Native Americans may predate this. Major lead mining occurred from the 1800’s until the late 1970’s. A few small lead mines operated by individuals persist to the present day.
