Glacier National Park

A little more than 100 years ago, there were as many as 150 glaciers strewn throughout Glacier National Park. By 2005, only 27 remained, and those glaciers are expected to disappear by 2030, if not earlier. Many of the plant and animal species that call the park home require cold water, meaning the ecosystem of the park may change dramatically when the glaciers are gone.
