A History of Cliffs: 1847-2017 Timeline
Cliffs celebrated our 170th year as a company in 2017. We are a company that pre-dates the first Industrial Revolution, with leaders who navigated business through wars, prosperity and depression eras. Now in the New Millennium, we can thank the ingenuity and hard work of our employees over the years for helping to make us into the largest iron ore producer in North America. We are very proud of the fact that steel starts here at Cliffs.
