Do we know these facts about Mount Kilimanjaro?


TANZANIANS got shocking news over the weekend, when it was officially declared that Mount Kilimanjaro had failed to make it to the New Seven Wonders of Nature, losing the coveted "Canon of Seven" to its only African rival; Cape Town's Table Mountains.

The first count of the global vote to elect the New 7 Wonders of Nature was announced in the night of Friday, November 11, 2011 in Switzerland.

Kilimanjaro, with its three volcanic cones, Kibo, Mawenzi, and Shira, is a dormant volcano in Kilimanjaro National Park, and the highest mountain in Africa at 5,895 metres or 19,341 feet above sea level - the Uhuru Peak.

The mountain is composed of three distinct volcanic cones: Kibo 5,895 m (19,341 ft); Mawenzi 5,149 m (16,893 ft); and Shira 3,962 m (13,000 ft). Uhuru Peak is the highest summit on Kibo's crater rim. Kilimanjaro is a giant stratovolcano that began forming a million years ago, when lava spilled from the Rift Valley zone.

Two of its three peaks, Mawenzi and Shira, are extinct while Kibo (the highest peak) is dormant and could erupt again. The last major eruption has been dated to 360,000 years ago, while the most recent activity was recorded just 200 years ago. Although it is dormant, Kibo has fumaroles that emit gas in the crater. Scientists concluded in 2003 that molten magma is just 400 m (1,310 ft) below the summit crater.

Several collapses and landslides have occurred on Kibo in the past, one creating the area known as the Western Breach. It is unknown where the name Kilimanjaro originates, but a number of theories exist.

European explorers had adopted the name by 1860 and reported that it was its Swahili name,with Kilimanjaro breaking into Kilima (Swahili for "hill, little mountain") and Njaro,whose supposed origin varies according to the theories—according to some it is an ancient Swahili word for white or for shining,or for the non-Swahili origin, a word from the Kichagga language, the word jaro meaning "caravan".

The problem with all these is that they cannot explain why the diminutive kilima is used instead of the proper word for mountain, mlima. The name might be a local joke, referring to the "little hill of the Njaro" being the biggest mountain on the African continent, since this is a nearby town, and guides recount that it is the Hill of the Njaro people.

A different approach is to assume that it comes from the Kichagga kilmanare or kileajao meaning "which defeats the bird/leopard/caravan". However this theory cannot explain the fact that Kilimanjaro was never used in Kichagga before in Europe in the mid-19th century.

An alternative theory is as follows: On November 10, 1848, the German missionary Rebmann wrote in his diary:"This morning we discerned the Mountains of Jagga more distinctly than ever." Jagga was the pronunciation of Chagga by Europeans. Kilimanjaro may also be the European pronunciation of the Chagga phrase that "Kile-lema-irho", meaning "we failed to climb it" in Kiuru, Kioldimoshi, Kimarangu, Kivunjo, Kikibosho, Kimachame and Kirombo, Kichagga in general.

If so, name itself, Kile-lema-irho/Kilimanjaro, would have been the Chagga way of explaining to kyasaka (newcomers) when they asked about the shining mountain top of Kibo and Mawenzi Peak. Kibo peak is more visible from the Kibosho Area, and Mawenzi from Marangu.

The Ki- prefix in Swahili has several underlying meanings. The old Ka- diminutive noun prefix (found now only as Kadogo - a small degree), merged with the Ki class. One of its meanings was to also describe something unique of its kind: Kilima, a single peak, as opposed to Mlima, which would better describe a mountain range or undulating country. Several other mountains also bear this prefix, such as Kilima Mbogo (Buffalo Mountain), just north of Nairobi in Kenya.

People with disabilities are also placed in this class, not so much as a diminutive idea; but a unique condition they possess: a blind or a deaf person, Kipofu and Kiziwi. This prefix "Ki-" in no way implies a derogatory sense. The name Kibo in Kichagga means "spotted" and refers to rocks seen on snowfields.

In the 1880s, the mountain, at that time spelled Kilima-Ndscharo in German following the Swahili name components, became a part of German East Africa after Karl Peters had persuaded local chiefs to sign treaties (a common story that Queen Victoria gave the mountain to her grandson Kaiser Wilhelm II is not true). When in 1889 Hans Meyer reached the highest summit on the crater ridge of Kibo, he named it "Kaiser-Wilhelm-Spitze" ("Kaiser Wilhelm peak").

That name was used until 1918, when after World War I the German colonies were handed over to the British empire. When Tanganyika gained its independence in 1961, this summit was named "Uhuru peak", meaning "Freedom peak" in Swahili. In 1861, the German officer Baron Carl Claus von der Decken and the young British geologist Richard Thornton (1838-1863) made a first attempt to climb Kibo, but "got no farther than 8,200 feet"(2,500 meters).

In 1862, Von der Decken tried a second time together with Otto Kersten. They reached a height of 14,000 feet (4,280 meters). In 1887, during his first attempt to climb Kilimanjaro, the German geology professor Hans Meyer reached the base of Kibo, but was forced to turn back, not having the equipment necessary to handle the deep snow and ice on Kibo.

The following year, Meyer planned another attempt with cartographer Oscar Baumann, but the mission was aborted due to consequences of the Abushiri Revolt. Meyer and Baumann were captured and held hostage, and only escaped after a ten thousand rupees ransom had been paid.

In 1889 Meyer returned to Kilimanjaro with the celebrated Austrian mountaineer Ludwig Purtscheller for a third attempt. Their climbing team included two local headmen, nine porters, a cook, and a guide.

The success of this attempt, which started on foot from Mombasa, was based on the establishment of many campsites with food supplies so that multiple attempts at the top could be made without having to descend too far.

After Meyer and Purtscheller pushed to near the crater rim on October 3, exhausted from hacking footsteps in the icy slope, they reached the highest summit on the southern rim of the crater on Purtscheller's 40th birthday, October 6, 1889. They were the first to confirm that Kibo has a crater, which was filled with ice at the time.

After descending to the saddle between Kibo and Mawenzi, Meyer and Purtscheller attempted to climb the more technically challenging Mawenzi next, but could only reach a 5096 m high subsidiary peak (later to be named Klute Peak) before retreating due to illness.

On October 18 they reascended Kibo to enter and study the crater, cresting the rim at Hans Meyers Notch. In total, Meyer and Purtscheller spent 16 days above 4,200 m during their expedition. The summit of Kibo wouldn't be climbed again until 20 years later (by the surveyor M. Lange in 1909), and the first ascent of the highest (5149 m) summit of Mawenzi was only on July 29, 1912, by the German climbers Edward Oehler and Fritz Klute, who christened it Hans Meyer Peak in Meyer's honour.

Oehler and Klute went on to make the third ascent of Kibo, via the Western route over the Drygalski Glacier. In 1989, the organizing committee of the 100-year celebration of the first ascent decided to award posthumous certificates to the African porter-guides who had accompanied Meyer and Purtscheller.

One person in pictures or documents of the 1889 expedition was thought to match a living inhabitant of Marangu, Yohani Kinyala Lauwo. Lauwo did not know his own age nor did he remember Meyer or Purtscheller, but he remembered joining a Kilimanjaro expedition involving a Dutch doctor who lived near the mountain and not wearing shoes during the 8-day affair. Lauwo claimed that he had climbed the mountain 3 times before World War I.

 The committee concluded that he had been a member of Meyer's team and therefore must have been born around 1871. Lauwo died on 10 May 1996 at the thus reconstructed world-record age of 124 or 125 and is now even often suggested as co-first-ascendant of Kilimanjaro.

Memorial recognizing Hans Meyer as the first European to "conquer" KilimanjaroThere are six official trekking routes by which to climb Mt Kilimanjaro, namely: Marangu, Rongai, Lemosho,Shira, Umbwe and Machame. Of all the routes, Machame is by far the most scenic albeit steeper route up the mountain, which can be done in six or seven days.

The Rongai is the easiest and least scenic of all camping routes with the most difficult summit night and the Marangu is also relatively easy, but accommodation is in shared huts with all other climbers.

As a result, this route tends to be very busy, and ascent and descent routes are the same. People who wish to trek to the summit of Kilimanjaro are advised to undertake appropriate research and ensure that they are both properly equipped and physically capable.

Though the climb is technically not as challenging as when climbing the high peaks of the Himalayas or Andes, the high elevation, low temperature, and occasional high winds make this a difficult and dangerous trek.

Acclimatisation is essential, and even then most experienced trekkers suffer some degree of altitude sickness. Kilimanjaro summit is well above the altitude at which high altitude pulmonary edema (HAPE), or high altitude cerebral edema (HACE) can occur.

Kilimanjaro has a large variety of forest types over an altitudinal range of 3,000 m (9,843 ft) containing over 1,200 vascular plant species. Montane Ocotea forests occur on the wet southern slope. Cassipourea and Juniperus forests grow on the dry northern slope.

Subalpine Erica forests at 4,100 m (13,451 ft) represent the highest elevation cloud forests in Africa. In contrast to this enormous biodiversity, the degree of endemism is low. However, forest relicts in the deepest valleys of the cultivated lower areas suggest that a rich forest flora inhabited Mt Kilimanjaro in the past, with restricted-range species otherwise only known from the Eastern Arc mountains.

The low degree of endemism on Kilimanjaro may result from destruction of lower elevation forest rather than the relatively young age of the mountain. Another feature of the forests of Kilimanjaro is the absence of a bamboo zone, which occurs on all other tall mountains in East Africa with a similarly high rainfall. Sinarundinaria alpina stands are favoured by elephants and African Buffalos elsewhere.

On Kilimanjaro these megaherbivores occur on the northern slopes, where it is too dry for a large bamboo zone to develop. They are excluded from the wet southern slope forests by topography and humans, who have cultivated the foothills for at least 2000 years.

This interplay of biotic and abiotic factors could explain not only the lack of a bamboo zone on Kilimanjaro but also offers possible explanations for the patterns of diversity and endemism. If true, Kilimanjaro's forests would serve as a striking example of the large and long-lasting influence of both animals and humans on the African landscape.

The period from 1912 to present has witnessed the disappearance of more than 80% of the ice cover on Kilimanjaro. From 1912-1953 there was 1% annual loss, while 1989-2007 saw 2.5% annual loss. Of the ice cover still present in 2000, 26% had disappeared by 2007.

While the current shrinking and thinning of Kilimanjaro's ice fields appears to be unique within its almost twelve millennium history, it is contemporaneous with widespread glacier retreat in mid-to-low latitudes across the globe. Unless trends change, Kilimanjaro is expected to become ice-free some time between 2022 and 2033.
