Zion National Park is best known for the surrounding canyon’s steep red cliffs. Almost 12,000 years ago, Zion's first peoples tracked mammoth, giant sloth and camel across southern Utah. About 8,000 years ago, though, these animals died out due to climate change and over-hunting. Farming tradition archaeologists call Virgin Anasazi. The Anasazi moved southeast 800 years ago, resulting in Paiute peoples moving to this land. In the 1860s, just after settlement by Mormon pioneers, flash floods destroyed towns and drought burned the crops. Only the will to survive saw Paiute, Anasazi, and European descendants through great difficulties.
A Congressional bill designating Zion National Park was signed into law in 1919. During the 1920s, visitation to the new national park increased steadily. These visitations particularly increased after the Union Pacific extended a spur rail line to Cedar. The park today is one of the most visited parks, popular for its views, trails, and history.
