# Coalville, Utah

Coalville is a city in and the county seat of Summit County, Utah, United States. It is part of the Salt Lake City, Utah Metropolitan Statistical Area. The population was 1,486 as of the 2020 census. Interstate 80 passes through the town, as well as the Weber River, which flows into Echo Reservoir, just north of Coalville.

## History

Coalville originally began as a settlement known as Chalk Creek. In 1853, Mormon Church president Brigham Young awarded hundreds of acres of farmland to trailblazer and trusted bodyguard "Return" Jackson Redden. Redden first visited the valley around 1846 while scouting trail ahead of advance Mormon pioneers. The first recorded settlement was Redden's ranch, spanning from 100 N. Main Street to beyond the Coalville City Cemetery where he is buried. In 1854, the territorial government in Utah offered a $1000 reward to anyone who could find coal within 40 miles of Salt Lake City. Four years later, Redden and associate Thomas Rhodes found a coal vein in the Chalk Creek area, and coal mining began in earnest. Hundreds of tons of coal were shipped to Salt Lake City, and soon a narrow gauge railroad was built. The settlement was then renamed Coalville, as a result of this early success.
Coalville was officially founded by William Henderson Smith, an early Mormon freighter. He noticed that wheat, spilled by other wagons moving through the area, would grow to maturity without being tended. In 1859, he signed Coalville into official township.
Early life in Coalville was difficult, and during winters, the settlers dealt with a constant scarcity of food. When food ran out, they would travel to Salt Lake City for supplies. The local Indian tribes were also hostile for a time, and the settlers built a fort on the advice of Brigham Young. In 1867, Coalville was incorporated.
By 1880, success in the coal industry led to the extension of the railroad into Park City. Then known as the Summit County Railway, the railroad continued to transport coal and was also used for Park City's silver mines.
Unlike most Mormon settlements in Utah and the intermountain west, Coalville city streets are not aligned to the true north. Main Street in Coalville is offset such that it runs slightly north-northwest, and Center street runs slightly east-northeast. Both the Thomas L. Allen House and the Summit Stake Tabernacle in Coalville are listed on the National Register of Historic Places.

## Geography and climate

According to the United States Census Bureau, the city has a total area of 3.3 square miles (8.5 km$^2$), of which 2.9 square miles (7.5 km$^2$) is land and 0.4 square miles (1.0 km$^2$) (12.27%) is water.
Coalville has a high-altitude, warm-summer humid continental climate (Köppen Dfb) that borders a subarctic climate (Dfc), characterized by extreme diurnal temperature ranges that range from extremely cold winter nights to hot afternoons in the summer. However, the high altitude and low humidity mean that mornings in the summer remain very cool, and frosts have occasionally occurred—even in July. Precipitation is moderate throughout the year, though with a minimum in summer, and snow accumulation is generally heavy due to the very cold nights between November and March, with a median of 60.1 inches (1.53 m) for the year.
Coalville is located at the intersection of two narrow valleys—formed by Chalk Creek and the Weber River. Like other valley locations in northern Utah, Coalville experiences pronounced temperature inversions associated with high-pressure systems during winter months, with low temperatures below 0 °F relatively common. Owing to this localized phenomenon, observed low temperatures are often significantly lower than those forecasted by national agencies.

## Economy

Some residents of the Coalville area pursue careers in farming, ranching, construction, public education, and county government—though many commute to the Wasatch Front. Ranchers in the area primarily raise beef and dairy cows, sheep, and mink. Crops such as alfalfa and wheat are also cultivated.
There is a small grocery store, a few restaurants, two motels, and several small gas/convenience stores. A health clinic serves residents of Coalville and other settlements in northern Summit County, as well as a dental office. Vacant commercial real estate continues to be a problem, especially along the main street, as is the case in many small towns in rural America—an effect of urbanization.
