The Crater Highlands or Ngorongoro Volcanic Highlands (Milima kasoko ya Ngorongoro , in Swahili) are a geological region along the East African Rift in the Arusha Region and parts of northern Manyara Region in north Tanzania. The Crater Highlands are made up of several large volcanic complexes, including the 2.4-2.2 Ma Lemagarut and 2.25-2.0 Ma Ngorongoro basalt-trachybasalt-trachyandesite volcanoes (Ngorongoro also contains trachydacite) and the 1.6-1.5 Ma Oldeani basalt-trachyandesite volcano.[1]
