For almost ten years from its founding on 25 March 1869, the town of Corinne prospered as the unofficial "Gentile Capital of Utah". As the Union Pacific and Central Pacific railroads approached their historic meeting place at Promontory Summit early in 1869, a group of former Union Army officers and some determined non-Mormon merchants from Salt Lake City decided to locate a Gentile town on the Union Pacific line, believing that the town could compete economically and politically with the Saints of Utah. They chose a location about six miles west of Brigham City on the west bank of the Bear River where the railroad crossed that stream. Named by one of the founders for his fourteen-year-old daughter, Corinne was designed to be the freight-transfer point for the shipment of goods and supplies to the mining towns of western Montana along the Montana Trail.
