Hubbard Glacier is a glacier located in eastern Alaska and part of Canada and it is North America’s largest tidewater glacier. The ice you see at the terminal face is approximately 450 years old and is over 2000 feet thick at some locations. The glacier was named in 1890 for Gardiner Hubbard, the first president of the National Geographic Society. The Hubbard Glacier is currently advancing while most glaciers are retreating worldwide. The Hubbard Glacier will and does react in an opposite fashion to most glaciers in a warming climate. This is not in contradiction with current global temperature increases.
