With the fog lifting and early morning light beginning to illuminating the surrounding sheer steep mountain cliffs lining the fjord we began to see bread crumbs of ice floating by leading us to Dawes Glacier. Reflecting back, I’m not sure which I was more fascinated with, the layers of mystical fog we had just passed through, the rugged step valley walls and snowcapped peaks or the wonderful chucks of ice floating along the sides of our ship’s hull. With the light the way it was, I decided to first focus on the ice and found myself running from one side of the ship to the other to “get the shot.”
The subsequent reading I’ve done explains that these small chucks of ice are called Bergy Bits and Growlers. These very small chucks of floating ice rise only about 3 feet out of the water. When trapped air escapes, as the iceberg melts, it sometimes makes a sound like the growl of an animal, hence their name.
Also, glacial ice is a different color from regular ice. It is blue because the dense ice absorbs every other color of the spectrum except blue – so blue is what we see. Sometimes the glacial ice appears almost turquoise because the crystalline structure strongly scatters blue light.

I had to keep reminding myself that the ice floating by was ancient. It was epic to see it.
