Francis E. Warren Air Force Base is described as a haunted location due to reports of spectral figures, including a long-deceased cavalryman and the ghost of "Gus Quarters," who allegedly died in a peculiar incident. These reports often include sightings of phantom maneuvers, a soldier in old cavalry uniform, and ghostly apparitions in the old hospital morgue. A long-dead cavalryman is said to refuse to leave his post, with sightings of the figure standing at attention on the side of buildings. The ghost of Gus, who supposedly hanged himself on a clothesline while fleeing an angry husband, is said to linger in "Gus Quarters". A spectral presence is reported to linger in the Missile Museum, though specific details are scarce. The basement of Building 34, which once served as a hospital morgue, is a site of reported ghostly sightings. Another location for paranormal activity, the security forces building is associated with the sightings of the cavalryman. The base is one of the most haunted military installations in the nation and is the oldest continuously active one.
