This represents the outside of the mountain to show its size, but I also show you the possible ways that can have the famous lift of Vikki. As you can see, the elevator can go down the mountain and very low, but it also has the peculiarity to go left and right under the mountain. This suggests that its base is even greater than was thought, or even that there is other base. Also, the house looks small on the mountain, but that's normal.
