Crew members aboard Coast Guard Cutter Mackinaw secure buoys and concrete anchors to the cutter's deck as they head to port fully loaded with buoys pulled from the Straits of Mackinac, Dec. 11, 2013. An early start to the ice season means the crew of Mackinaw has to race to complete Operation Fall Retrieve before the ice floes set firm and damage the navigational buoys.
