I purchased the book "Disney Mountains: Imagineering at its Peak" to kill time while waiting for the fireworks at Disneyland. One thing I noticed was that Mount Prometheus, which is perhaps the most elaborate, incredible, and awe inspiring Disney Mountain ever built, only got four pages in this otherwise decent book.
Five pages was devoted to Grizzly River Run, a short sighted project that includes a river rafting ride that is practically in every Six Flags park in the world
The Mount Prometheus section includes two pieces of incredible concept art, a photo of 20K Leagues' outdoor queue and exit (a great looking area, but not the best looking area), and a photo of the mountain erupting not bigger than my thumb. They don't include a large photo of a wide shot of Mount Prometheus in all its glory nor do they include a shot of the incredible rockwork and lava. Not even the drilling machine.
You could probably write a whole book about the creation of Mount Prometheus and Mysterious island. Even this book says, "Mount Prometheus is the largest man-made rock structure the Imagineers have ever built." So it only deserves four pages? In a book about Disney Mountains? This is it, this is the big one.
In any case, I was surprised they even included a section on Mount Prometheus at all. Disney isn't in the business of advertising another company's wares. I'm sure the makers of this book received notes from Disney to shorten the Mount Prometheus section and not to gush too much about it.
We wouldn't want people skipping that trip to Walt Disney World to visit Tokyo now would we?
