Yellowstone National Park became the first national park in the world in 1872, and is Wyoming's biggest tourist attraction. In 1807, John Colter, one of Yellowstone Country's first visitors told others about "a region of the Rocky Mountains steaming with geysers, bubbling with mud pots, and abounding with wildlife."
About 600,000 years ago, a huge volcanic eruption here created the world's most extensive area of geyser activity, containing more than 10,000 thermal features, the most famous of which is Old Faithful. However, most people come to Yellowstone because of the plentiful species of birds, mammals and game fish that inhabit this beautiful 2.2 million acre park.
Newly done.
