If you are looking for very basic geographical information about Kilimanjaro, Wikipedia has a good set of information about the mountain, its history and the volcanoes. Read Wikipedia on Kilimanjaro.
I especially enjoyed the Nasa picture from the ground level of the mountain. Although not in preportion, you get a great view of the other extinct volcanoes as well as Kilimanjaro’s little sister, Mt. Meru.
