Stark Mountain in Pokémon Platinum
Inside Stark Mountain

Stark Mountain is the volcano at the end of Route 227 in the post-game Battle Zone. In Platinum, Charon leads what remains of Team Galactic here to steal the Magma Stone and awaken Heatran. You beat Mars and Jupiter, who then quit the team, Buck joins you in the main cavern, and Looker arrests Charon in the deepest room. After you talk to Buck at the Battleground, Heatran appears in that chamber at level 50.
