Hubbard Glacier is a tidewater glacier in the U.S. state of Alaska and the Yukon Territory of Canada. From its source in the Yukon, the glacier stretches 122 km (76 mi) to the sea at Yakutat Bay and Disenchantment Bay. It is the longest tidewater glacier in Alaska, with an open calving face over ten kilometers (6 mi) wide.
Look at all the marine life and see what a true giant glacier can do.
