Heber City, named for Mormon Apostle Heber C. Kimball, was selected as the county seat. The last boundary change occurred in 1914 when Duchesne County was created out of the eastern half of Wasatch County. The county produces hay, dairy products, sheep, and cattle. During the early 1900s, after the Denver and Rio Grande Railroad completed a line into the county from Provo, Heber City became an important shipping terminal for wool and sheep. In 1922 the Union Pacific Railroad constructed a spur from Park City to the mines west of Keetley and began shipping lead, zinc, and silver ore.
