Glacier National Park
Glacier National Park became the nation’s tenth national park in 1910 and in 1932 was combined with Canada's Waterton Lakes National Park to become the world's first International Peace Park, the Waterton-Glacier International Peace Park. Archaeological studies have found human presence in Glacier dating back more than 10,000 years, a time when parts of the park were covered in mile-deep ice. In 1850, Glacier was home to 150 glaciers; today, only 25 remain large enough to be considered glaciers, and it's predicted that the park will be without glaciers by 2030. Vulture Glacier, Two Ocean Glacier, Rainbow Glacier, and Gem Glacier are visible from the Going-to-the-Sun Road.
