Crew members aboard Coast Guard Cutter Mackinaw use a boathook while recovering Wind Point North Shoal Lighted Buoy 14 in Lake Michigan, Dec. 9, 2013. The Mackinaw crew is participating in Operation Fall Retrieve, which entails decommissioning larger navigational buoys and replacing them with smaller, more buoyant winter aids that will mark navigational channels in the Great Lakes during the winter months.
