the world), it was established by the U.S. Congress in 1872; it
covers 3,468 sq mi (8,983 sq km). The Gallatin, Absaroka, and
Teton mountain ranges extend into it. Yellowstone has unusual
geologic features, including fossil forests and eroded basaltic
lava flows. It also has 10,000 hot springs, which erupt as steam

series of forest fires temporarily laid waste to large areas of
the park. Learn more about Yellowstone National Park with a free
