The melting of Glacier National Park’s namesakes stand out as a very tangible effect of global climate change. When the park was created, in 1910, there were 150 glaciers. Today, there are only 25, and scientists predict the 7,000-year-old slabs of ice will disappear entirely within a few decades. Reporter Allison Mills recently hiked to the retreating margin of one of the park’s most iconic glaciers, Grinnell, with U.S. Geological Survey researcher Dan Fagre and his crew.
