All glaciers located in the Alaska, USA, in North America.
In spite of Alaska's remoteness, its glaciers have been studied for more than 150 years. More than 1,000 journal articles, books, and U.S. Geological Survey publications present details about individual glaciers or glacierized regions. Today, most Alaskan glaciers at lower elevations are retreating. However, about a dozen large valley glaciers, including Hubbard, Harvard, Meares, Taku, and Lituya Glaciers (all tidewater or former tidewater glaciers), are currently thickening and advancing. At higher elevations glaciers are thickening or exhibit no change.
