Nature
Piegan Glacier is a small glacier in Glacier National Park, Montana, occupying a cirque on the southeast slope of Piegan Mountain just below the summit at about 8,800 to 8,200 feet above sea level. In 2005 it covered roughly 62 acres after losing about 10 percent of its surface area since 1966. Photographs from 1930 and 1998 showed relatively little change during that earlier span, so its later shrinkage reflects a more recent phase in the ongoing changes affecting the park’s high mountain glaciers.
