Piegan Glacier is in Glacier National Park in the U.S. state of Montana. The glacier is situated in a cirque on the southeast slope of Piegan Mountain and just below the summit at an elevation between 8,800 and 8,200 ft (2,700 and 2,500 m) above sea level.[3] The glacier covered an area of approximately 62 acres (0.25 km2) in 2005, a 10 percent reduction in its surface area since 1966.[2] Comparing images of the glacier taken in 1930 with those from 1998, indicates that the glacier experienced relatively little change during that period.[4]
