President Calvin Coolidge proclaimed the area around Glacier Bay a national monument under the Antiquities Act on February 25, 1925. Glacier Bay became part of a binational UNESCO World Heritage Site in 1979 and became a Biosphere Reserve in 1986. Most of Glacier Bay is designated a wilderness area which covers 4,164 square miles (10,784 km) and you can actually feel the remoteness of the expansive backcountry spread out before you.
There are fifteen tidewater glaciers in the park. Glaciers descending from high snow-capped mountains into the bay create spectacular displays of ice and iceberg formation. Every few minutes a huge avalanche of snow breaks off into the sea, called “calving” and the rumble and crash as the ice plunges splashing into the bay is dramatic, sending ripples of waves toward the ships watching the display.
Not bad for an excursion you didn’t have to pay for! (sort of)
