The geothermal features in Yellowstone National Park were largely responsible for its designation as the world's first national park in 1872. These features are a global treasure. Nowhere else in the world can you find the array or number of geysers, hot springs, mud pots, and fumaroles found in Yellowstone. More than 75 percent of the world's geysers, including the world's largest are in Yellowstone’s seven major basins.
