From Bulbapedia, the community-driven Pokémon encyclopedia.
Evolution Mountain (Japanese: 進化山 Evolution Mountain) is an anime-exclusive mountain located in between the Safari Zone and Cinnabar Island. At its base lies Stone Town. Judging by its name, and the fact that the people of Stone Town use evolutionary stones to evolve their Pokémon, it is possible that a large number of evolutionary stones can be found on the mountain.
