The Matterhorn bobsled ride in Disneyland was the first steel tube rail coaster ride developed. You may not think of the Matterhorn ride as a real mountain, but the Sierra club did. They decided after the mountain was built to try and climb it and they did. Walt Disney had them scale the mountain again for the grand opening. Climbers were hired after this by Disney to perform the feat repeatedly for the enjoyment of the guests.
