Sault Ste. Marie, MI -  The crew of the Coast Guard Cutter Mackinaw tends to a winter buoy channel marker that was pushed off station by thick ice along the shipping lane.  This crewmember uses a sledgehammer to ensure wooden blocks are positioned tightly against the marker to keep it from shifting on the deck.  .  USCG photo by PA1 Adam Eggers
