Mackinaw breaks ice in Duluth

The US Coast Guard cutter Mackinaw left her moorings at the DECC at 9 am this morning (March 17, 2013) to break ice in the Duluth Superior harbor. She returned to the DECC around 11:30, dropped some folks off, and then went under the Duluth Aerial Lift Bridge on her way to Whitefish Point at the other end of Lake Superior.
