The Geraldine Milwaukee Depot, built in 1913, is a great example of one of America's small town, turn-of-the-century wooden depots. It has a unique design and was given special attention since the town's namesake, Geraldine Rockefeller, was the daughter of the principal Milwaukee stockholer, William A Rockefeller. The exterior has been fully restored and the building is located on its original site next to the still active short-line Central Montana Railroad. Displays document the role the railroad played in developing the large agricultural area, including a freight room and ticket/express office.
