Olympus Mons
From Tardis Wiki, the free Doctor Who reference
Olympus Mons was a large volcanic mountain located on Mars. The location was involved in the Earth's counter-offensive against the Ice Warriors during the Thousand Day War. Members of the United Nations Third Tactical Response Brigade dropped on Mars, suffering heavy casualties.
The bar known as the Ice Maiden was originally located halfway up Olympus Mons and served as an R&R stop during the war. (NA: Transit)
The central control facility for the Sol Transit System was located inside the volcano, as well as the power grid established by Fusion Corp. (NA: Transit)
