Royal Teton Ranch of the Church Universal and Triumphant, Montana

A complex of above ground and underground buildings in remote southwest Montana, constructed by the religious organization known as the Church Universal and Trimphant (CUT), whose worldwide membership was once estimated at 30,000 to 50,000 people. In the late 1980's, leader Clare Prophet urged her followers to prepare for nuclear Armageddon, which she maintained would be initiated by the USSR. She died in 2009 from Alzheimer's disease.
