The story

How Gallatin Gateway came to be

From Wikipedia’s history of Gallatin Gateway.

Read it all →

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.
