World's Greatest Concentration of Geysers

It's 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 wilderness, home to grizzly bears, wolves, and herds of bison and elk, the park is the core of one of the last, nearly intact ecosystems in the Earth’s temperate zone.
