This is the second roller coaster to operate inside of the Nightmare Mine building. This was an identical unit that replaced the original. Unlike the original, this until was not repainted black and kept its original red, white and blue colors as it was from Fun Junction in Grand Junction, Colorado. It's unknown when the roller coaster was removed, but by 2016, the Nightmare Mine building was used for a haunted house attraction.
According to an advertisement by IRM (International Rides Management), a ride broker, this roller coaster was built in the 1970s.
