Mine Train Thru Nature's Wonderland was a Disneyland attraction created in 1960. It is an upgrade from it's former self, the Rainbow Caverns Mine train, which opened in 1956. The attraction covered a very large chunk of Frontierland and featured over 200 Audio-Animatronics and featured themes and scenery from Walt Disney's popular True-Life adventure films. As guests board one of 4 battery powered faux steam locomotive trains, they passed by the sprawling town of Rainbow Ridge which also served as the loading area for the pack mule attraction. From there the guests were treated to views of Beaver Valley, Cascade Peak, Bear Country (not the land known as Critter Country today) the Living Desert, Cactus Forest, Balancing Rock Canyon, and the magnificent Rainbow Caverns.
The attraction lasted until 1977 when it was replaced by a much higher speed train ride, Big Thunder Mountain. Today remnants of the original Mine Train attraction are still around, like large Buttes from the Living Desert, the buildings from Rainbow Ridge (Re-arranged for the Big Thunder Loading area), although half buried in concrete the rock formations for the geyser corner, the tunnels to and from Cascade Peak, Bear Country pond, and some animals AA's from the attraction. Other remnants that survived that have been torn down in later years include Cascade Peak, the bear scratching his back on the tree, and soon, the last remaining mine train staged as a wrecked train.
