Apocalypse

Before Apocalypse, this site hosted Psyclone, an Arrow Dynamics wooden coaster built with a steel-reinforced support structure that opened in 1991. Psyclone struggled with a rough, jarring ride quality typical of Arrow's wooden designs from that period, and it closed permanently in 2006 after a relatively short run compared to other wooden coasters of its era.

Great Coasters International rebuilt the site almost entirely with new all-wood construction, reopening it in 2009 as Apocalypse. GCI's wood coaster designs are known for smoother, more comfortable ride quality than Arrow's steel-reinforced hybrids, and the rebuild let the ride's 2,877-foot layout deliver airtime hills and banked turns without the rattling harshness that had defined Psyclone.

The new ride adopted an end-of-days mining-town theme, framing the queue with a story of a settlement destroyed by earthquakes — loose narrative dressing that ties the coaster's identity to the surrounding Underground zone it now shares with the launch coaster West Coast Racers. Apocalypse stands as one of the more successful examples of a park fully replacing a struggling wooden coaster's structure rather than simply retracking or removing it outright.
