What region of the U.S. was the focus of ice-breaking operations by the U.S. Coastguard in 2011?
Great Lakes Region
The Great Lakes region of North America is a bi-national Canadian-American region that includes portions of the eight U.S. states of Illinois, Indiana, Michigan, Minnesota, New York, Ohio, Pennsylvania and Wisconsin as well as the Canadian province of Ontario.
The U.S. Coast Guard began its annual ice-breaking operation in Northern Michigan on Monday, Dec. 19.
As ice growth continues on the Great Lakes over the upcoming weeks, additional icebreakers will join in on the operation.
