Named to honor the first Prince Albert of Monaco, a pioneering polar explorer in the early 20th century, this immense glacier flows into the far end of the Liefdefd Fjord. When ice calves off the cliff and into the ocean, the sound can be heard for miles around. Imposing ship-size icebergs floating in the middle of the fjord are the result of such activity. According to mapping studies, the glacier has retreated by more than two miles in the last 50 years.
