On August 5, 2011, Six Flags Great America announced on their official Facebook page that the Iron Wolf would be closed on September 5, 2011: "After a long 21 year history at the park, we will be removing Iron Wolf. Make sure to get your last rides in – Iron Wolf’s Last Stand is September 5". 'The Last Stand' is also a reference to the slogan afforded to Apocalypse. Iron Wolf's former site would be taken over in 2014 by a custom RMC wooden roller coaster.
