Happy Birthday, Glacier Bay National Park! Designated from a national monument to a national park on this day in 1980, Glacier Bay covers 3.3 million acres of rugged mountains, dynamic glaciers, temperate rainforest, wild coastlines and deep sheltered fjords. From sea to summit, the Alaska park offers limitless opportunities for adventure and inspiration. And the most incredible blue water you’ll ever see.
