We entered Yakutat Bay and Disenchantment Bay, at the end of which is Hubbard Glacier. It is the longest (76 miles) tidewater glacier in Alaska, with an open calving face over 6 miiles wide and 300 ft high. This glacier is one of the few in Alaska that is advancing. Hubbard Glacier was named in 1890 after Gardiner G. Hubbard who was the founder and first president of the National Geographic Society.
