Mount Ararat is a snow-capped, dormant volcanic cone in Turkey. It has two peaks: Greater Ararat and Lesser Ararat . The Ararat massif is about 40 km in diameter. The Iran-Turkey boundary skirts east of Lesser Ararat, the lower peak of the Ararat massif. It was in this area that, by the Tehran Convention of 1932, a border change was made in Turkey's favour, allowing it to occupy the eastern flank of Lesser Ararat.
