Crew members aboard Coast Guard Cutter Mackinaw lower the winter mark for Wind Point North Shoal into the water in Lake Michigan, Dec. 9, 2013. After several days of working aids to navigation, the Mackinaw crew had a full buoy deck that had to be offloaded before the crew could continue working aids to navigation as part of Operation Fall Retrieve.
