Guests on board National Geographic Venture enjoyed the final day of their voyage by exploring Tracy Arm. Naturalists and guests alike were delighted to explore this fjord system by Zodiac, cruising around icebergs to get a better look at both Sawyer and South Sawyer Glaciers. The iconic harbor seals of Tracy Arm popped up around the Zodiacs as we marveled at the size of these glaciers. As guests enjoyed their final day, everyone came together on the decks to cheer on those brave enough, or perhaps foolhardy enough, to try a polar plunge in the frigid Alaskan waters. Guest reported it to be exhilarating.
