Explanation:
Operation Taconite, to be specific, was the operation focused in the Great Lakes region. It took place in 2011. It was the largest Coast Guard ice breaking operation to date, and it centered around several places such as, the lakes Superior and Michigan, the St. Mary’s River, the Straits of Mackinac, and the northern Lake Huron.
