Arthur M. Anderson with limestone from Calcite, Michigan

arthurmanderson2008Apr17_9425
The Arthur M. Anderson is due in port this morning with a cargo of limestone loaded in Calcite, Michigan. Much of the limestone that is brought up from lower lakes ports is used on the Iron Range in the production of taconite pellets. The finished pellets, with the limestone inside, come down by rail to a Lake Superior port where it is loaded into boats and taken to steel mills on the lower Great Lakes. The limestone makes a round trip there but we have to wait until the taconite is fed into steel mills, steel is produced and we buy a car up here before the taconite completes its round trip. Above, the Anderson departs Duluth this past April.
