Heatran is encountered at level 70. Heatran lives at the top of Stark Mountain. Go to the top of Stark Mountain with a trainer named Buck. Buck will then take the Magma Stone and leave Stark Mountain, which causes the mountain to act up. Talk to Buck at his house, and he will put the stone back. Go back to the top of Stark Mountain and Heatran will be there in the place of the Magma Stone.
