Glacier National Park: Watching the Ice Disappear

Glacier National Park had about 80 glaciers in 1910; fewer than 30 remain today. We cover why most of the dramatic valleys and peaks were actually carved by ice age glaciers gone 12,000 years ago, how fast today's smaller glaciers like Grinnell are retreating, and why the carved landscape will outlast the ice by tens of thousands of years.
