Pack Ice

Drift ice swirl, north Atlantic

The swirl is one of the shapes one sees consistently in nature, from the shape of the galaxies to the form of a nautilus shell to the patterns of whirlpools and tornadoes. I found the pattern mesmerizing as I flew over the north Atlantic in between Iceland and Greenland. I snapped the photo, since I had never seen anything like this before. It was a very propitious trip, as it inspired my later travels to the Arctic, in Greenland and Iceland, starting exactly 10 months later.
