Park story
According to Disney "legend," a freak snowstorm on January 11, 1977, in the area led to the development of Florida's first ski resort. Ski lifts were put up, toboggan runs were laid down, and an entire resort area blossomed around the mountain of snow. Naturally, because of the normal temperatures in Florida, the snow dissipated very quickly, and the snow rapidly turned into slush. This left behind a collection of waterlogged yet snowless ski jumps and chair lifts. The operators were preparing to cut their losses and walk away. However, they were interrupted by a loud yell coming from the summit of the mountain of melting snow, and looked up to see a blue alligator sliding down the mountain at top speed. Ice Gator, the blue cartoon mascot of the park, then landed in a pool of melted snow at the base of the mountain with a thunderous splash. The ski resort operators suddenly saw the park's potential, and the mountain of snow became Disney's Blizzard Beach, "the most slushy, slippery, exhilarating water park anywhere!"[7]
As the story goes in Disney's promotional materials, slalom courses, bobsled, and toboggan runs became downhill water slides. The creek of melted snow that formed at the base of the mountain became a relaxing tube ride. The chairlift carried swimmers instead of skiers. The ski jump became the "tallest and fastest water slide in the world."[7]
Looks like an April Fool's joke...
