From the record
“The Historic Crail Ranch Buildings listed in the National Register of Historic Places are two rustic cabins, the remnants of a homestead dating to the late 1890s in Gallatin County, Montana in the area now known as Big Sky. The historic cabins are part of the Crail Ranch Homestead Museum, which depicts the homestead era in Big Sky from about 1896 to 1970 through displays of objects, photographs and documents on loan from a descendant of the original homesteaders.”
