Glacier National Park spreads out over 1 million acres and is home to over 130 named lakes, rugged mountains, and dense forests. Established as the 10th national park in the United States, it was carved by ancient glaciers, creating U-shaped valleys. It once had 150 glaciers; only about 25 remain today, with projections indicating they may vanish by 2030 due to climate change. The area was home to multiple tribes, such as the Blackfeet, Salish, Kootenai, and Pend d’Oreille, who have inhabited the region for over 10,000 years.
