The founding of Alberton, Montana, has its roots in the iconic Milwaukee Railroad, which began its quest for a route across America to the Pacific Coast in the early 1900s. The path they chose led them to a narrow Clark Fork River corridor just west of Missoula, Montana.
Railway Company President Albert J. Earling himself chose the north bank of the Clark Fork River here at Alberton. Two families were homesteading at the time: Henry and Catherine Brown, who had been working the narrow bench land since 1891, and Amadie and Phoebe Agnes Poirier, who began homesteading here in 1899.
