On August 17 , 1959 the Old Faithful Inn was shaken by the 1959 Hebgen Lake earthquake which collapsed the dining room fireplace chimney and damaged the huge lobby fireplace , reducing the number of usable hearths from eight to two . The building was partially shaken loose from its foundations , and access to some of the upper levels had to be restricted due to safety concerns . There were no deaths or serious injuries at the Inn as a result of the earthquake . The dining room fireplace was finally rebuilt in 1985 , but the outside portion of the lobby fireplace chimney was replaced with a single steel pipe , visible in many exterior photos
