Mount Seleya was at the far end of Vulcan's Forge. (ENT: "The Forge") The mountain was also roughly thirty-seven kellicams north of the T'Karath Sanctuary. (TNG: "Gambit, Part II" ) By 2285, a temple had been constructed on the mountain, which incorporated an altar and an adjacent building known as the Hall of Ancient Thought. A long flight of steps led from the base of the mountain, an area that had a fountain and could be used as a landing base for craft, up to the temple. The altar was sparsely furnished and included a Vulcan gong. (Star Trek III: The Search for Spock)
