Harbor seals are the most widespread pinniped species in the world. They range as far south as Baja California in Mexico, and as far north as Artic Canada and Greenland. In the colder areas of that vast distribution, they sometimes make themselves at home on floating chunks of ice below tidewater glaciers.
Glaciers are constantly on the move, flowing slowly downhill under the force of their own weight. When that path leads them into the ocean, they’re called tidewater glaciers. During the summer, harbor seals, up to several thousand at a time, congregate in Alaska’s tidewater glacier fjords.
