Hubbard Glacier is the longest tidewater glacier in Alaska extending 76 miles from its source on Mt. Logan in the Yukon. The cliff face you sail along is over six miles wide, 300 to 400 feet from the top to sea level and 300 feet from sea level to the bottom. As Hubbard is advancing, it creaks and groans as it moves and is a very actively calving glacier. This makes for some exciting moments when the huge chunks of ice crash into the Bay creating a wonderful sound called 'white thunder' by the Tlingit people.

Situated at the head of Yakutat Bay, in Disenchantment Bay, the sail up to Hubbard is both leisurely and beautiful. Small ice bergs, sometimes with sea birds or seals resting on them, float in the water which is glacial blue. Seals calve on the ice bergs here as Orca whales do not visit the bay.

Disenchantment Bay was named by the Spanish explorer Alejandro Malaspina in 1791, who was disenchanted that he had not found the Northwest Passage. Hubbard Glacier was named after Fr. Bernard Hubbard, SJ, known as 'the Glacier Priest' who led annual expeditions to Alaska from 1927 until shortly before his death in 1962.

The smaller Turner Glacier adjacent to Hubbard is overshadowed by its neighbor.
