Mount Kilimanjaro Furtwangler Glacier is a small remnant of an enormous icecap which once crowned the summit of Mount Kilimanjaro. This icecap has retreated significantly over the past century and between 1912 and the 2000, 82 percent of the glacial ice on the mountain has disappeared. The retreat of glacial ice on the summit is expected to continue and by the year 2020, all the glaciers on top of the mountain may be gone
