History
Salesville was one of the pioneer towns, named for Z. Sales, who secured a saw mill started by J. J. Tomlinson, continuing the business on the West Gallatin river several years. With his family, he established the town on his property, the name of the town being changed in 1927 to Gallatin Gateway, by The Milwaukee Road, when the town became the terminus of the branch line from Three Forks, carrying passengers for the trip through Yellowstone National Park by way of Gallatin Canyon.

The passenger depot that was built at that time was established in the commodious Gallatin Gateway Inn built by the railroad. A good brick school house, some substantial business blocks and comfortable homes are found there. Opening June 17, 1927, The Gallatin Gateway Inn was touted as one of the most luxurious and beautiful hotels of the day. In 1980 the Inn received Historic Landmark designation after an extensive restoration effort (the Milwaukee Road left the Northwestern U.S. that year).
