Pueblo, Colorado, the seat of Pueblo County. It is at the junction of the Arkansas River and Fountain Creek, 105 miles (169 km) south-southeast of Denver, and some 4,600 feet (1,400 m) above sea level. Pueblo, the fifth largest city in Colorado, is in a farming, ranching, and coal-mining area. Iron and steel, automotive parts, railway equipment, and processed foods are produced. The city is headquarters for San Isabel National Forest, and is a resort center. The Colorado State Fair is held here.

The area was visited by the explorer Zebulon Pike in 1806. A trading post was established in 1842, and four years later, an unsuccessful Mormon settlement. A new settlement, called Fountain City, was founded in 1859 by a group of prospectors; it became the city of Pueblo in 1886. The city was severely damaged by an Arkansas River flood in 1921.
