|U.S. - Canadian icebreakers escort convoys of ore. The 3 day trip from northern Minnesota |
to Gary, Indiana, took 13 days
"The U.S. Coast Guard (USCG) reports today they have concluded Operation Taconite, the nation’s largest domestic ice operation which has enabled commercial shipping traffic to operate on the U.S. Great Lakes through one of the most brutal winters on record. Besides various liquid and dry cargoes, vast amounts of iron ore from the northern shores of Lake Superior were carried to the steel mills in Lake Erie and Lake Michigan while supported by Coast Guard icebreakers.
The Coast Guard notes that although official statistics have not been released, the 2013-14 winter season likely produced the thickest and most expansive ice cover the Great Lakes has experienced in 35 years."
