2x8 - Rocky & Bullwinkle & Friends

Boris is ready to derail the upcoming train with Rocky and Bullwinkle aboard. Boris contacts Fearless Leader to get approval from a fellow named: Mr. Big. He's disapproved because if Bullwinkle's gone, how will they find Mt. Flatten? So Boris tries to put the switch back to where it was, only to find it stuck. So he runs on the tracks waving a red flag. Rocky notices, and has Bullwinkle pull the emergancy brake cord. The train stops and Rocky and Bullwinkle go to meet the hero, who turns out to be a grizzled old prospector named Mojave Max (Boris) and his sidekick Death Valley Dotty (Natasha). All of the sudden, the train leaves because Capt. Peachfuzz drives it. Rocky, Bullwinkle, Max, and Dotty search for Mt. Flatten noticing a road marker pointing the direction to Mt. Flatten. Rock after rock with the same sign until they come to a rock pointing in the opposite direction. But, if Mt. Flatten's right where they're standing, where is it?
