Wyoming Frontier Prison is known as The Old Pen, with a reputation of being the most haunted prison in the state. Of all the inmates that were held there, one of the most grisly and psychopathic was Andrew Pixley who was executed in the gas chamber in 1965. It's claimed he's not moved on from where he met his demise and justice was served. However the area is rich in a history of bloodthirsty outlaws.
In 1872, desperadoes caught breaking the law in Wyoming were sent to serve their sentence at the Wyoming Territorial Prison, which opened in 1872 as a U.S. Penitentiary on 190 acres. Later it became Wyoming's first State Penitentiary. For the next 30 years it was known as the "Big House Across the River".
