Yellowstone National Park

Legend has it that here, where the Firehole and Gibbon Rivers join to form the Madison River, members of the Washburn-Langford-Doane Expedition gathered on the last night of their journey through the Yellowstone country on September 19, 1870. Discussing the wonders they had seen, they developed an idea that this land should be set aside for the benefit of all people. Less than two years later President Ulysses S. Grant signed the law creating Yellowstone National Park. The first national park.
