The freighters are still scarce on the Great Lakes. Reports say U.S. Steel has scaled back steelmaking at its Indiana mill because the frozen Great Lakes cut off the mill’s access to iron ore. In a letter to its customers, the company states, it has reduced production at the Gary Works complex’s blast furnaces and steelmaking due to “unprecedented ice conditions on the Great Lakes.” Ice continues to cover much of Lake Superior, preventing ships from transporting iron ore from Minnesota’s Iron Range to northwestern Indiana steel mills. The Gary Works locations is equipped to produce 7.5 million net tons of steel each year, and employs some 5,800. It is the nation’s largest steel mill inhabiting some seven miles along Lake Michigan.
