This photo was taken in early July 2017, from a small tour boat out of the village of Ilulissat, Greenland, during a 13-hour, round-trip cruise to the face of a tidewater glacier. While cruising through the massive Disko Bay on the way to that glacier, we passed dozens of huge icebergs. Many were the size of small mountainous landscapes; but this was one of two or three that reminded me of the sheer, steep-walled, flat-topped icebergs I’d seen in photographs of icebergs in the Southern Ocean off Antarctica.
