Each January on the frigid waters of the northern #GreatLakes, freighters scramble to make final deliveries of iron ore to steel mills before the Soo Locks — an engineering marvel connecting Lake Superior with points to the south and east — shut down for 10 weeks of maintenance. But as temperatures hover in the single digits, freighters, like the Burns Harbor, photographed here by @samuelhodgson, often get stuck. It’s the United States Coast Guard Cutter Mackinaw’s job to free them. The 57-member crew on the 240-foot icebreaker often frees 4 or 5 commercial ships a day, working sometimes from sunup until midnight. The @ニューヨーク・タイムズ journalist Mitch Smith and the photographer @samuelhodgson rode along on a mission to cut loose the marooned Burns Harbor. “The icebreaker’s sound is overwhelming and unrelenting, like a chain saw on a boulder,” Mitch writes. “The whole ship vibrates. But in a noisy instant, the Mackinaw exposes bright blue water beneath a section of ice that had been thick enough to host a hockey game.” Each time the icebreaker ushers a ship to safety, the crew records a mark on the ship’s window. The Burns Harbor brought a new tally for the season: 47. Visit the link in our profile to read more about this intricate boat ballet.
