Original caption: “The Northwind Hits It! The Antarctic. The World of Ice. With her diesel-electric motors, with power ranging up to 10,000, going full blast, the Coast Guard’s icebreaker Northwind charges the ice pack at top speed. Following the terrific crash, the Northwind rides half a ship’s length up onto the ice before she is stopped. She backs away and charges again and again until the area is broken up and ready for the thin-hulled vessels which follow her. This arduous duty of the Northwind was a day after day routine, as her part of the work of the Byrd Expedition to the Antarctic. This photo was taken from the Northwind’s helicopter, which proved so valuable in scouting out loads in the ice, far in advance of the ships.” 1/5/1947. Note the J2F Duck on her deck.
