Coalville is a city in Summit County, Utah, United States. It is part of the Salt Lake City, Utah Metropolitan Statistical Area. The population was 1,382 at the 2000 census. It is the county seat of Summit County. Interstate 80 runs through the town, as well as the Weber River which runs into the Echo Reservoir just north of Coalville.
Coalville was founded in 1859 by William Henderson Smith, an early Mormon freighter. He noticed that wheat spilled by other wagons moving through the area would grow to maturity. He subsequently convinced four families to settle in the area with him. The settlement was originally called Chalk Creek.
Early life in Chalk Creek 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 Native Americans were also hostile for a time, and the settlers built a fort on advice of Brigham Young.
