9 Things You Didn’t Know About Glacier National Park


On May 11, 1910, President William Taft signed a bill into law establishing Glacier National Park. The country’s 10th national park, Montana’s Glacier preserves 1 million acres of glacier-carved peaks and valleys, pristine turquoise lakes and streams, and dense ancient forests for all to enjoy. Learn more about the Crown of the Continent as we celebrate this iconic national park.

1. Glacier National Park is a part of the world’s first international peace park. The vision for a park was to celebrate peace and friendship between the United States and Canada. In 1932, Glacier and Waterton Lakes National Park in Alberton, Canada, were designated the Waterton-Glacier International Peace Park. Today, the parks collaborate seamlessly in their preservation, fire management and research efforts. Learn more about Glacier’s international designations.

2. Glacier straddles the Continental Divide, allowing for extreme weather. That’s because the opposing Pacific and Arctic airs meet at the Divide, creating a dramatic clash of weather. In one instance just outside the park’s eastern boundary in Browning, Montana, the temperature was noted as dropping 100 degrees in just 24 hours. When heading out for a day in the park, be sure to bring rain gear and extra clothes.
