Inside the mines and megamachines of the Iron Range
Minnesota's Iron Range essentially fueled America's success story as the country's largest source of iron ore. Curious Minnesota journeyed north to U.S. Steel's Keetac taconite mine to see how some of the state's largest machines make the raw ingredients for American steel. The trip was inspired by the Munson family's quest to find the state's largest machine, which was the subject of a January Curious Minnesota column. LINKS: What is the largest machine in Minnesota?
