It was among the first hotels in Montana with telephones in every room,[citation needed] and offered travelers access to Yellowstone National Park.

[citation needed] The hotel was originally built to promote tourism on the Milwaukee Road's Olympian and Columbian passenger trains.

It was added to the National Register of Historic Places on January 24, 1980, a month before the Milwaukee Road left the Northwestern United States.

Following a foreclosure in February 2013, the Inn was purchased and renovated by M&M Hospitality.
