Mount Kilimanjaro lies on the border of Tanzania and Kenya, just south of the Equator. To the west lies the Great African Rift Valley, created by tremendous tectonic forces which also gave birth to a string of other volcanoes.
The three summits of Mount Kilimanjaro, Shira, Kibo and Mawenzi are all of very recent origin. Shira and Mawenzi both have suffered considerable erosion and only jagged peaks remain. Kibo, the central, youngest and highest peak has survived as an almost perfect cone.
