This Landsat satellite image shows Bering Glacier in Alaska, the largest glacier in North America. Although the glacier has been retreating and thinning recently, it still surges about every 20 years or so. âCredit: NASA image by Robert Simmon, based on data provided by the Landsat 7 Science Team.
According to the National Snow and Ice Data Center, Malaspina Glacier in Alaska is one of the most famous examples of this type of glacier, and is the largest piedmont glacier in the world.
