The newest documentary series from Fox Nation features actor Kevin Costner on a journey into some of the nation’s most beautiful national parks, as well as one former U.S. president’s mission to preserve the country’s frontier.

The three-part series, titled Yellowstone to Yosemite with Kevin Costner, follows Costner as he explores the history of former President Theodore Roosevelt‘s 1903 Yosemite expedition with naturalist and environmental advocate John Muir. During their journey, Muir informed the president of the need to preserve the nation’s beautiful lands and forests, which eventually paved the way for Roosevelt to create a more structured National Park System, including five national parks and 150 national forests, during his presidency.
