Stark Mountain is on the island with the battle frontier that you unlock at the end of the game. You can access the island by going on the boat with the sailor at Snowpoint City (the sailor is south of the ice gym). You'll arrive in the fight area (south-west of the island). Stark Mountain is north-east of the island. Hope this helps :)
