In the outskirts of Disneyland Paris' Frontierland, beyond Phantom Manor and past the edge of Thunder Mesa, there is the splendor of the great American outdoors.  Traversed only by those who sail down the Rivers of the Far West aboard the Molly Brown or the Mark Twain, it's untouched, splendid, and beautiful.  The rugged wilderness and geological formations echo the likes of Yellowstone National Park, with geysers and craggy boulders and verdant trees.  It's an idyllic and lovely scene that harkens to the spirit of the Old West, where every day was an adventure exploring the frontier!
