Yellowstone National Park
It’s a Wonderland. Old Faithful and the majority of the world’s geysers are preserved here. They are the main reason the park was established in 1872 as America’s first national park—an idea that spread worldwide. A mountain wildland, home to grizzly bears, wolves, and herds of bison and elk, the park is the core of one of the last, nearly intact, natural ecosystems in the Earth’s temperate zone.
First called the Elk River by the Crow and Blackfoot Indians that hunted the abundant game along its banks, the Yellowstone River was given its modern name by the early fur trappers that encountered the golden sandstone cliffs along its middle and lower course. To this day, the Yellowstone remains remarkably unchanged – from its headwaters in the snow-capped peaks of Wyoming to its confluence with the Missouri River in North Dakota, this majestic, expansive, free-flowing river constitutes the longest undammed river in the lower 48 states.
