Coalville originally began as a settlement known as Chalk Creek. 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, 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.
