Yellowstone National Park is one of the earth's most famous places.  Established in 1872 as the world's first national park, it has preserved remarkable natural wonders like Old Faithful Geyser and cultural icons such as Old Faithful Inn.  For centuries, it was home to the Shoshone, Crow, Bannock, Blackfeet, and other Indian tribes, but these groups were banished in the 1870s by park promoters who feared that tourists would not visit if American Indians lived there.  Almost immediately after its establishment, Yellowstone became the primary destination for tourist travel to the American West following the Civil War.  By 1900, it was a vast tourist success, and today it is both a world biosphere preserves and a world heritage site.
