Hubbard Glacier - Alaska, USA

Located in eastern Alaska, Hubbard Glacier is the largest tidewater glacier in North America. It measures 76 miles long, and plunges 1,200 feet below the oceans surface. Many cruise ships sail by the glacier, and this is when the true scale of the glacier becomes apparent, as it towers over the decks of the ship.

Whales, seals, and otters can all be spotted swimming by the glacier. On shore, brown bears, moose, and black tail deer roam around, while sea birds fly high above in the sky.
