Officials at Six Flags Great America, Gurnee, Illinois, announced late Friday that Iron Wolf, which debuted in 1990, will be shut down on Labor Day. After a 21-year history, Iron Wolf will be removed from the park. Iron Wolf's last stand will be on September 5.
When Iron Wolf opened, it was billed as the world's tallest and fastest stand-up looping coaster, in which riders are secured in a standing position over a bicycle-style seat.
Located in the County Fair section of the amusement park, the ride features a 90-foot drop and reaches speeds of 55 mph.
