Iron County, Utah: History
Evidence of Fremont culture habitation ranging from 750 to 1250 AD exists in present Iron County. Petroglyphs of differing periods were carved into the walls of Parowan Gap NW of Parowan. Paiutes roamed the Parowan Valley in the centuries before Euro-American exploration; their descendants are now represented by the Southern Paiute Indian Reservation, which is headquartered in Cedar City.
The Domínguez–Escalante expedition traveled through the Iron County area on October 12, 1776. Fur trapper Jedediah Smith is the first recorded Anglo-American to pass through the area (1826). Settlement of the area began in 1851, when LDS President Brigham Young directed members from the northern colonies to move into the area. A settlement, Coal Creek, sprang up in 1851; it later became Cedar City. To provide a local government structure, the State of Deseret legislature created the county on January 31, 1850, although it was not organized until January 17, 1851, with description stretching from the future Colorado, across Utah, and into the future Nevada. It was named "Little Salt Lake County" at creation, but on December 3, 1850, a legislative act changed its name to Iron County. Its borders were altered in 1850, 1852, 1854, 1856, and 1861. Also, in 1861, the federal government created the Colorado Territory, which administratively removed Iron County areas east of 109 degrees longitude.
The county borders were altered in 1862. Also, in 1862, the federal government created the Nevada Territory, which administratively removed Iron County areas west of 114 degrees longitude. Further boundary adjustments were passed in 1866, 1880, 1882, 1883, and 1884. The final adjustment was made in 1892; the county borders have remained in their current arrangement.
