Mystic Lake Hydroelectric Facility, Hoist House, On west slope of West Rosebud Creek, 1 3/4 miles northeast of Mystic Lake Dam, Fishtail, Stillwater County, MT

Significance: The hoist house dates to project construction and contributes to the significance of the Mystic Lake Hydroelectric Facility. It is a component of the facility's narrow-guage railroad, a type of resource not typical to hydroelectric power installations but which engineers for Mystic Lake found a necessity due to the extremely steep and rugged terrain at the project site. The hoist house also serves as fairly well-preserved example of a vernacular form of industrial architecture from the middle decades of the first half of the 20th century.
