Alberton was established by the Milwaukee Railroad when they were running their trans-continental line to the Pacific Coast. When they chose this route, on the north side of the river, they determined that they needed a Division Point to service the steam engines that were being used at that time. This location, 30 miles west of Missoula was chosen. They bought right-of-way and land for the yards and town from Henry and Catherine Brown who had homesteaded it in 1891 and from Charles Amadie and Phoebe Agnes Poirier who had taken their homestead in 1899.
Recently the Milwaukee depot has been restored and is visible from I-90. Alberton is the gateway to the Alberton Gorge, favored by whitewater rafters, avid anglers and hunting enthusiasts.
Alberton is located approximately 30 miles west of Missoula, in western Montana (Glacier Country).
