The Powell County Museum and Arts Foundation has operated structured paranormal investigations and ghost tours at the Old Montana Prison since the late 1990s. The staff maintains a reports log from visitors, investigators, and museum personnel covering nearly three decades of after-hours access.

Reports concentrate in three areas. The first is the Death Tower, the prison's elevated isolation cell, where visitors describe a heaviness of air, cold pockets, and intermittent voices. The second is the upper tier of the main Cell House, where the 1959 riot was concentrated and where reported phenomena include footsteps, distant clanging on metal bars, and the sense of a presence at the end of long corridor sightlines. The third is the Women's Prison, where visitor accounts include voices reading as female and the sound of crying.

The Foundation's overnight investigation program runs from 8pm to 2am and includes areas of the prison not open during daytime hours. The minimum age is 15; minors must be accompanied by a parent or guardian.

The site has appeared in regional Montana tourism press and on televised paranormal programming. The Foundation presents the reports as documentary artifact and emphasizes the historical record of the prison's operation alongside the paranormal vocabulary.

West Virginia Penitentiary in Moundsville opened in 1876, modeled on Joliet Prison's Gothic Revival design at half scale. Over 119 years of operation it housed more than 36 homicides within its walls, 94 executions, and was ranked among the top ten most violent correctional facilities in the United States. A 1986 West Virginia Supreme Court ruling that its 5-by-7-foot cells constituted cruel and unusual punishment contributed to its closure in 1995.

Old Montana State Prison

Deer Lodge, MT

The Montana Territorial Prison in Deer Lodge received its first inmate on July 2, 1871. The cornerstone was laid June 2, 1870, after the territorial government selected Deer Lodge as the site in 1867. The prison served as Montana's primary penal institution from its 1871 opening through 1979, when a new facility replaced it. A 1959 riot held the prison and surrounding town under inmate control for 36 hours, killing three people. The facility was added to the National Register of Historic Places in 1976.
