Glacier National Park Is Melting Away

Description:  Glacier National Park used to have 150 glaciers and it now has 25. Photographic evidence in this video shows how drastically the glaciers are being shaped by a warming planet. This phenomenon can be used to show two forms of freshwater (ice and water) in elementary science and as evidence for global warming in secondary.

Glacier National Park is losing its iconic glaciers to a changing climate. In the mid-1800s, this Montana landscape was covered by 150 glaciers-today only 25 remain. To show the decrease in glacier size, scientists from the USGS Northern Rocky Mountain Science Center photograph the same areas where glaciers were photographed in the early 1900s.
