Appaloosan Mountains
The Appaloosan Mountains were a mountain range located in Equestria.
Historically, the mountains were the potential site for an ancient Diamond Dog civilization, or at least a digging site, as the mines were littered wit ruined statues of Diamond Dogs. The mountain had at least two doorways, the Ziggy Stardust gateway and the Walk Tall, Act Fine, Never Look Back door. The Mane Six traveled throughout them on their way to the Changeling Kingdom in order to save the Cutie Mark Crusaders from Queen Chrysalis.
