Bering Glacier is a
glacier in the
U.S. state of
Alaska. It currently terminates in
Vitus Lake south of Alaska’s
Wrangell-St. Elias National Park, about from the
Gulf of Alaska. Combined with the
Bagley Icefield, where the snow that feeds the glacier accumulates, the Bering is the largest glacier in
North America. Warmer temperatures and changes in precipitation over the past century have thinned the Bering Glacier by several hundred meters. Since 1900 the
terminus has retreated as much as . The Bering Glacier exhibits "surges", acceleration events of the flow rate of the glacier, every 20 years or so. During these periods the glacier terminus advances. The surges are generally followed by periods of retreat, so despite the periodic advances the glacier has been shrinking overall. Most glaciers along the Alaskan coast have been retreating along with the Bering Glacier.
