Mount Tar'Hana was a volcano on the planet Vulcan. Tours of its crater were available. In 2154, T'Pol told Commander Trip Tucker that Tar'Hana still occasionally erupted. (ENT: "Home") Mount Tar'Hana was first mentioned in the Last Unicorn Games role-playing guide The Way of Kolinahr, which features an atlas of the planet Vulcan. It is an example of one of the few non-canon references from a book that became canon.
