Along the western edge of Disneyland, rises a craggy peak of mossy cliffs, tangled tree roots, and thorny briar patches. This attraction — part animatronic carnival, part kid-friendly log flume — is known as Splash Mountain, and thanks to the technical wizards at Walt Disney Imagineering, it really looks like an authentic summit. But of course, it’s not; it was built in the late 1980s at a reported cost of some $75 million. It’s a very fun ride — and possibly the strangest in the entire Disney empire, since it’s essentially a giant $75 million monument to a movie that Disney has kept out of circulation for more than 30 years.
