Natural wonder Africa

Mount Kilimanjaro

Mount Kilimanjaro is the highest mountain in Africa. It is in Tanzania. It is an old volcano with snow and ice on top.

Mount Kilimanjaro, in northeastern Tanzania, is what UNESCO calls the highest mountain in Africa: its top is 5,895 meters high. It is a huge volcanic mountain standing alone above the plains, and as you climb it you pass through farms, forest, moorland and high alpine desert to its icy top.

Kilimanjaro is a volcanic massif of three principal cones, Kibo, Mawenzi and Shira, rising about 4,877 m above the plains of northeastern Tanzania to 5,895 m, Africa's highest point. Its summit ice has lasted more than 10,000 years, but between 1912 and 2011 it lost more than 85 percent of its mass.

Discover Kilimanjaro

Kilimanjaro is the highest mountain in Africa.

It stands all by itself above flat, grassy land. Its top is white with snow and ice. It is in the country of Tanzania.

Mount Kilimanjaro rises in northeastern Tanzania, near the border with Kenya, about 225 kilometers south of Nairobi. Its highest point, on the peak called Kibo, is 5,895 meters above sea level, which Britannica calls the highest point in Africa.

Kilimanjaro is not just one peak: it is a massif, a big block of mountain made of three volcanoes, Kibo in the middle, Mawenzi to the east and Shira to the west. It stretches about 80 kilometers from east to west. Standing alone, it rises almost 4,900 meters above the plains around it.

Britannica places Kilimanjaro in northeastern Tanzania near the Kenya border, about 160 km east of the East African Rift System and 225 km south of Nairobi. The massif extends about 80 km east to west. Kibo, its central cone, rises to 5,895 m, and UNESCO describes the mountain as rising 4,877 m above the surrounding plains, which lie at about 1,000 m.

UNESCO calls Kilimanjaro National Park, about 75,575 ha, the protector of the largest free-standing volcanic mass in the world and a superlative natural phenomenon for its height, form, snow cap and isolation above the savanna. The park was established in 1973 to cover the mountain above the tree line and six forest corridors, was inscribed in 1987, and was extended in 2005 to include the natural montane forest of the former Kilimanjaro Forest Reserve.

Three volcanoes in one

Kilimanjaro was made by volcanoes.

Long ago, hot melted rock came out again and again. It piled up into a giant mountain. The tallest part is called Kibo. It has a big hole on top called a crater.

Kilimanjaro was built by three volcanoes. Shira, in the west, is now only a ridge, what is left of an earlier crater. Mawenzi, in the east, is the worn-down core of an old summit, jagged and steep, 5,149 meters high.

Kibo, in the middle, is the youngest and the highest. It still has the shape of a classic volcano, a cone with a crater on top, and inside its crater sits a smaller cone that still shows small signs of volcanic activity. A wide saddle of land at about 4,500 meters links Kibo and Mawenzi.

Britannica describes three principal volcanoes: Kibo (center), the youngest and highest, which retains a typical cone and crater; Mawensi (Mawenzi) to the east, 5,149 m, the highly eroded older core of a former summit, cleft by gorges; and Shira to the west, a ridge at about 3,962 m that is the remnant of an earlier crater. An 11 km saddle at about 4,500 m joins Kibo and Mawenzi.

Kibo's snow-clad dome holds a caldera on its southern side about 2 km across and some 300 m deep, with an inner cone that displays residual volcanic activity. Britannica calls the three cones extinct volcanoes, while NASA's Earth Observatory describes Kilimanjaro as a dormant stratovolcano; the two sources classify it differently. Below the saddle the mountain slopes in a typical volcanic curve to the plains at about 1,000 m.

From forest to ice

Climbing Kilimanjaro is like visiting many places at once.

At the bottom, there are farms and forests with monkeys. Higher up, giant plants grow on open moors. Near the icy top, only tiny mosses and lichens grow.

As you go up Kilimanjaro, the plants change in bands, called vegetation zones. Around the bottom is dry scrub on the plains. Then come farms on the well-watered southern slopes, then thick cloud forest. Above the forest is open moorland, then high, dry alpine desert, and finally the icy summit, with only mosses and lichens.

On the moorland grow strange giant plants: the giant lobelia and the giant groundsel. The forests are home to elephants, buffalo and eland, a kind of large antelope, as well as black-and-white colobus monkeys, blue monkeys and small antelopes called duikers, and many birds, including the rare Abbot's starling.

UNESCO identifies five main vegetation zones from base to summit: lower slopes, montane forest, heath and moorland, alpine desert and summit. Britannica describes the sequence as semiarid scrub on the surrounding plateau, cultivated and well-watered southern slopes, dense cloud forest, open moorland, alpine desert, and moss and lichen communities. The moorlands hold two notable giants, Lobelia deckenii and the giant groundsel Senecio johnstonii cottonii.

The forests shelter elephants, buffalo and eland, along with black-and-white colobus and blue monkeys, bushbuck and duikers, and a rich birdlife including the rare Abbot's starling. UNESCO notes that the mountain is very rich in mammal species, many of them endangered, though it is not inscribed for biodiversity. Pressures on elephants, buffalo and antelope and logging in the forest reserve were integrity concerns at inscription; the park is connected to Amboseli National Park, but corridors to Arusha and Tsavo National Parks have been encroached, affecting wildlife migration.

The shrinking ice

There is ice on top of Kilimanjaro, even though it is near the Equator.

The ice is getting smaller. Scientists climb up to measure it and learn what is happening.

Kilimanjaro is in the tropics, close to the Equator, yet ice has sat on its summit for more than 10,000 years, because the air at the top is very cold and dry. Only Kibo has a permanent ice cap.

But the ice is shrinking fast. Between 1912 and 2011, the mass of ice on the summit fell by more than 85 percent. NASA explained in 2012 that rising air temperatures may play a part, but other causes may matter as much or more: the air around the mountain has become drier, so less fresh snow falls to feed the ice, and fewer clouds let more sunshine warm it. Scientists keep measuring the ice to understand how it is changing.

NASA's Earth Observatory reported in 2012 that, despite its tropical location, Kilimanjaro's dry, cold summit air has sustained large quantities of ice for more than 10,000 years, and ice-core studies show it survived warm spells, droughts and abrupt climate shifts. Between 1912 and 2011 the summit ice mass decreased by more than 85 percent, and several scientists then predicted it would be gone by 2060.

NASA notes that rising air temperatures due to global warming could be contributing, but that an increasingly dry regional atmosphere, which starves the ice fields of fresh snow and reduces cloud cover so that more solar energy reaches the ice, may matter as much or more. On a September 2012 expedition, NASA glaciologist Kimberly Casey found that the northern ice field, which had been developing a hole since the 1970s, had split into two for the first time.

People of the mountain

Many people live on the lower slopes of Kilimanjaro.

They grow coffee, bananas and other crops. The town of Moshi sits at the bottom of the mountain.

The Kilimanjaro region is one of Tanzania's leading coffee-growing areas. Chaga (Chagga), Pare, Kahe and Mbugu peoples live in the region, and farmers grow coffee, bananas, corn, beans, potatoes and other crops. The town of Moshi, at the southern foot of the mountain, is the main trading center and the starting point for many climbs.

German missionaries Johannes Rebmann and Johann Ludwig Krapf reached the mountain in 1848; at first people in Europe did not believe there could be snowy mountains so close to the Equator. In 1889 Hans Meyer and Ludwig Purtscheller became the first people recorded reaching the top of Kibo.

Britannica describes the Kilimanjaro region as one of Tanzania's leading producers of mild coffee, barley, wheat and sugar, with crops also including sisal, corn, beans, bananas, wattle bark, cotton, pyrethrum and potatoes. It is home to the Chaga (Chagga), Pare, Kahe and Mbugu peoples, and Moshi, at the southern foot, is the chief trading center and base for ascents.

The mountain became known to Europeans when German missionaries Johannes Rebmann and Johann Ludwig Krapf reached it in 1848, though reports of snow-capped mountains so close to the Equator were not believed for more than a decade. The Kibo summit was first reached in 1889 by the German geographer Hans Meyer and the Austrian mountaineer Ludwig Purtscheller. The mountain and its forests became a game reserve early in the 20th century and a national park in 1973.

Visiting safely

Climbers walk up Kilimanjaro slowly.

The air at the top is thin and cold. Going slowly helps their bodies get used to it. They look after the forests and animals on the way.

Kibo's top can be reached without climbing ropes or special mountaineering gear, so thousands of hikers try each year. But the summit is very high, at 5,895 meters, where the air is thin and freezing. Health experts explain that the body can get used to thin air only up to about 5,200 meters, and only with time, so they advise going up gradually.

The mountain is a national park and World Heritage Site. UNESCO notes that its forests and wildlife have faced pressure from logging and from land being taken over along the paths animals use to move between parks. It also says tourism must be planned carefully, so visitors help by respecting the park, its forests and its animals.

Because Kibo's summit can be reached without mountaineering equipment, Britannica notes, thousands of hikers attempt the ascent each year; Moshi is the base for ascents. The summit, at 5,895 m, lies above the roughly 5,200 m limit to which the CDC's Yellow Book says the human body can adjust to moderate oxygen shortage, and the Yellow Book stresses that acclimatization takes time, with the crucial acute phase over the first 3 to 5 days, and that risk depends on altitude and rate of ascent.

Conservation pressures are recorded by UNESCO: logging in the former forest reserve, pressure on elephants, buffalo and antelope, and the encroachment of wildlife corridors to Arusha and Tsavo National Parks. The 2005 extension brought the montane forest into the national park, which UNESCO says fulfills the integrity criteria, and it asks that the property's boundaries be updated to match.

    Show the answer

    To give their bodies time to get used to thin air

    Going slowly helps their bodies get used to the thin air.

    The air is thin at the top, and the body needs time to adjust to it.

    The summit exceeds the roughly 5,200 m limit for adjusting to moderate hypoxia, and acclimatization takes days.
