The national park that boasts the highest mountain in North America has known human habitation for at least 11,000 years. But it wasn't until 1906 that conservationists proposed a bill, which finally passed in 1917, to preserve the Denali region as a national park. Historic Denali National Park is a vibrant narrative that covers different parts of the park's history, from the Native Americans and the early explorers to park visitors today.
