A month after the official arrival of spring, the U.S. Coast Guard has officially concluded the country's largest domestic ice operation known as Taconite after five months of ice breaking operations in the Northern Great Lakes. Spring, at last, has arrived with the conclusion of the operation on Thursday.
Official numbers haven't yet been released, but the 2013-14 winter is said to have produced the thickest and most expansive ice cover the Great Lakes have seen in 35 years.
Operation Taconite includes all of Lakes Superior and Michigan, the northern half of Lake Huron, the St. Marys River, and the Straits of Mackinac. Operation Taconite is planned and run by Coast Guard Sector Sault Ste. Marie, Michigan.
