THE summit of Kilimanjaro is, at 5891,77 metres, some three metres lower than previously supposed, Eberhard Messner, member of a German-Tanzanian geological expedition, said on Thursday. The highest mountain on the African continent, in northern Tanzania, it had previously been put at 5985 metres. A 21-member team of researchers from Germany and Tanzania measured the height of Kilimanjaro’s Uhuru peak using satellite technology, Messner explained. The world’s highest mountain, Everest, in the Himalayas of Nepal, has already been measured accurately using the same global positioning system (GPS). It towers 8850 meters above sea level, two meters more than shown on current maps, the National Geographic Society reported earlier this month.
