Mount Kilimanjaro is the highest mountain in Africa, located in Northeast Tanzania, near the Kenya border. Kilimanjaro is an extinct volcano, and is one of the most massive in the world. It towers 15,000 feet above the surrounding arid plains, and 2.5 square miles of its surface are over 18,500 feet. 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.
