FALLON COUNTY
The Milwaukee Railroad entered Eastern Montana in 1908 on its way to the West coast. Following it, came homesteads, businesses, schools and churches. In 1913, folks in this area successfully elected to split from Custer County to form Fallon County. Later that year, Fallon split to form Carter County to the South. Fallon again lost area in 1914 and 1915 to help establish Wibaux and Prairie Counties. To learn more about the rich history of Fallon County, visit the local chamber or the O’Fallon Museum.
