Sevier County, Utah

Evidence of indigenous peoples residing in Sevier County up to 5,000 BP has been unearthed.[3] The Fremont culture of Native Americans occupied the area from about 2000 to 700 BP.[4] The Clear Creek site contains native petroglyphs from that period.

In Utah, the Numic- (or Shoshonean) speaking peoples of the Uto-Aztecan language family evolved into four distinct groups in the historical period: the Northern Shoshone, Goshute or Western Shoshone, Southern Paiute, and Ute peoples. This territory's central and eastern sections were occupied primarily by various bands of the Ute.[5]

The first modern sighting of the Sevier River was most likely by the Catholic fathers Silvestre Vélez de Escalante and Francisco Atanasio Domínguez, on their expedition to California in 1776.[6] The Old Spanish Trail was the route they mapped. Over the next century, this trail carried fur trappers, hunters, government officials, traders, and settlers.

Settlement of this area began when Richfield was first settled. Mormon settlers arrived on June 15, 1864, most of whom had emigrated from Scandinavian countries. Because of the growth in this small community, the people soon petitioned Utah Territory officials about a separate county.[7]

On January 16, 1865, the Utah Territory legislature created the county, with the area annexed from Sanpete County. It was named for the Sevier River.[8] The county seat was Big Spring (later named Richfield). The county borders were adjusted in 1866, 1880, 1890, and in 1921. A clarification of boundary lines corresponding to government survey lines was completed in 1931, marking the present configuration of Sevier County.[9]

Although the county was in place by 1865, much of Sevier County was abandoned in the Black Hawk War in 1867. Attempts to resettle the area were not successful until 1870. By 1874, 753 residents lived in the area.[10]

Sevier County terrain consists of semi-arid but arable rolling areas punctuated by northeast–southwest mountain ridges, usually forested.[11] The highest point is Fish Lake Hightop in the Central Utah Plateau, at 11,633 ft (3,546 m) ASL.[12] The county has a total area of 1,918 square miles (4,970 km²), of which 1,911 square miles (4,950 km²) is land and 7.8 square miles (20 km²) (0.4%) is water.[13]

As of the 2000 United States Census, there were 18,842 people, 6,081 households, and 4,907 families in the county. The population density was 9.86 people per square mile (3.81 people/km²). There were 7,016 housing units at an average density of 3.67 units per square mile (1.42 units/km²).

There were 6,081 households, of which 43.00% had children under 18 living with them, 70.10% were married couples living together, 7.80% had a female householder with no husband present, and 19.30% were non-families. Of the 6,081 households in Sevier County, 155 are unmarried partner households: 137 heterosexual, 11 same-sex male, and seven same-sex female. 17.60% of all households were made up of individuals, and 9.40% had someone living alone who was 65 years of age or older. The average household size was 3.03, and the average family size was 3.44.

For every 100 females, there were 99.20 males. For every 100 females aged 18 and over, there were 97.40 males.

The median income for a household in the county was $35,822, and the median income for a family was $40,110. Males had a median income of $32,632 versus $19,228 for females. The per capita income for the county was $14,180. About 8.30% of families and 10.80% of the population were below the poverty line, including 12.80% of those under age 18 and 8.50% of those aged 65 or over.

Interstate 70 runs through the county. As Richfield is about halfway between the major cities of Los Angeles, California and Denver, Colorado, it has built a hospitality industry, with motels and restaurants serving travelers.

Fremont Indian State Park is found in the Clear Creek Canyon, adjacent to I-70. It is noted for its archaeological remains from the ancient Native American Fremont culture. Its museum displays found artifacts.

Sevier County is traditionally Republican. In no national election since 1936 has the county selected the Democratic Party candidate (as of 2020).
