Changes

Construction began on Walt Disney World’s Splash Mountain in 1990<ref> http://www.florida-project.com/walt-disney-world-photos/magic-kingdom/frontierland/splash-mountain </ref>. In order to build Chick-A-Pill Hill, (the structure which would eventually house Splash Mountain, ) the [[Frontierland]] train station on the [[Walt Disney World Railroad]] had to be removed. After the hill was built, the train station reopened and guests could now see the Zip-A-Dee-Lady scene inside Splash Mountain as the train passed by<ref name= "Jack1"/>.  The rock formations on Chick-A-Pill Hill were first sculpted and then reinforced with rebar, wire mesh and sprayable concrete. When completed, the hill stood 87 feet tall and housed caves, swamps and bayous. Also built was a 950,000 gallon water reservoir which supplies water for the attraction.  Splash Mountain (like Thunder Mountain before it) was designed to be controlled by computers. There are two main ride control computers which monitor the attraction. If the two computers don't both agree on the millions of the commands being sent to the ride, they will stop the ride automatically. Splash Mountain was also built with an infra-red intrusion system that alerts cast members if somebody steps outside of their log. When completed Splash Mountain took up 9.2 acres of land, including 2,600 feet of track<ref name= "Jack1"/>. Splash Mountain began its soft openings on July 27 , 1992 and it was officially dedicated October 2nd<ref name= "Korkis"/>.
