Montana

S4 E2: Big skies, big adventure, and big spirits: this is Montana. It's where fertile plains collide with the Rocky Mountains and the country's fastest land mammals run the grasslands known as the American Serengeti. It's also where Lewis and Clark faced towering stone obstacles and Custer faced an even more daunting foe. This aerial journey showcases the Treasure State's mountains and milestones, its legends and landmarks, all from spectacular heights.
