The Blackfoot Tribe refers to Glacier as the "Backbone of the World". It's easy to see why from the park's eastern side, where the mountains rise suddenly from rolling plains. Glacier's mountains are almost entirely made of sedimentary rock. What were once ancient seabeds were lifted and pushed more than 50 miles east from where they formed. The line of that movement is called the Lewis Thrust Fault. In relatively recent geologic time, glaciers carved the seabeds to create the park we see today.
