Table Mountain (Huri ?oaxa Khoekhoe language for where the sea rises, Afrikaans: Tafelberg) is a flat-topped mountain forming a prominent landmark overlooking the city of Cape Town in South Africa. It is a significant tourist attraction, with many visitors using the cableway or hiking to the top. The mountain forms part of the Table Mountain National Park. Table Mountain is home to large array of fauna and flora, most of which is endemic.

FeaturesEdit
The main feature of Table Mountain is the level plateau approximately 3 kilometres (2 mi) from side to side, edged by impressive cliffs. The plateau, flanked by Devil's Peak to the east and by Lion's Head to the west, forms a dramatic backdrop to Cape Town. This broad sweep of mountainous heights, together with Signal Hill, forms the natural amphitheatre of the City Bowl and Table Bay harbour. The highest point on Table Mountain is towards the eastern end of the plateau and is marked by Maclear's Beacon, a stone cairn built in 1865 by Sir Thomas Maclear for trigonometrical survey. It is 1,086 metres (3,563 ft) above sea level, and about 19 metres (62 ft) higher than the cable station at the western end of the plateau.
The cliffs of the main plateau are split by Platteklip Gorge ("Flat Stone Gorge"), which provides an easy and direct ascent to the summit and was the route taken by António de Saldanha on the first recorded ascent of the mountain in 1503.
The flat top of the mountain is often covered by orographic clouds, formed when a south-easterly wind is directed up the mountain's slopes into colder air, where the moisture condenses to form the so-called "table cloth" of cloud. Legend attributes this phenomenon to a smoking contest between the Devil and a local pirate called Van Hunks. When the table cloth is seen, it symbolizes the contest.
Table Mountain is at the northern end of a sandstone mountain range that forms the spine of the Cape Peninsula that terminates approximately 50 km to the south at the Cape of Good Hope and Cape Point. Immediately to the south of Table Mountain is a rugged "plateau" at a somewhat lower elevation than the Table Mountain Plateau (at about 1000 m), called the "Back Table". The "Back Table" extends southwards for approximately 6 km to the Constantia Nek-Hout Bay valley. The Atlantic side of the Back Table, is known as the Twelve Apostles, which extends from Kloof Nek (the saddle between Table Mountain and Lion's Head) to Hout Bay. The eastern side of this portion of the Peninsula's mountain chain, extending from Devil's Peak, the eastern side of Table Mountain (Erica and Fernwood Buttresses), and the Back Table to Constantia Nek, does not have single name, as on the western side. It is better known by the names of the conservation areas on its lower slopes: Groote Schuur Estate, Newlands Forest, Kirstenbosch Botanical Gardens, Cecilia Park, and Constantia Nek.

GeologyEdit
The upper approximately 600 m portion of the 1 km high table-topped mountain, or mesa, consists of 450-510 million years old (Ordovician) rocks belonging to the two lowermost layers of the Cape Fold Mountains. The uppermost, and younger of the two layers, consists of extremely hard quartzitic sandstone, commonly referred to as "Table Mountain Sandstone" (TMS), or "Peninsula Formation Sandstone" (as it is known as at present), which is highly resistant to erosion and forms characteristic steep grey crags. The 70 m thick lower layer, known as the "Graafwater Formation", consists of distinctively maroon-colored mudstones, which were laid down in much thinner horizontal strata than the Table Mountain Sandstone strata above it. The Graafwater rocks can best be seen just above the contour path on the front of Table Mountain, and around Devils Peak. They can also been seen in the cutting along Chapman's Peak Drive. These rocks are believed to have originated in shallow tidal flats, in which a few Ordovician fossils, and fossil tracks have been preserved. The overlying TMS probably arose in deeper water, either as a result of subsidence, or a rise in the sea level. The Graafwater rocks rest on the basement consisting of Cape Granite. Devil's Peak, Signal Hill, the City Bowl and much of the "Cape Flats", however, rest on heavily folded and altered phyllites and hornfelses known informally as the Malmesbury shales. The Cape Granite and Malmesbury shales form the lower, gentler slopes of the Table Mountain range on the Cape Peninsula. They are of late Precambrian age, pre-dating the "Graafwater rocks" by at least 40 million years.
The basement rocks are not nearly as resistant to weathering as the TMS, but significant outcrops of the Cape Granite are visible on the western side of Lion's Head, and elsewhere on the Peninsula (especially below Chapman's Peak Drive, and The Boulders near Simon's Town). The weathered granite soil of the lower slopes of the Peninsula Mountain range are more fertile than the nutrient-poor soils derived from TMS. Most of the vineyards found on the Cape Peninsula are therefore found on these granitic slopes of the Table Mountain range.
The mountain owes it table-top flatness to the fact that it is a syncline mountain, meaning that it once was the bottom of a valley (see diagram on the right). The anticline, or highest point of the series of folds that Table Mountain was once part of, lay to the east, but that has been weathered away, together with the underlying softer Malmesbury shale and granite basement, to form the "Cape Flats". The "Cape Flats" form the isthmus that connects the Cape Peninsula to the Mainland. The Fold Mountains reappear as the Hottentots-Holland Mountain range on the mainland side of the "Cape Flats". What has added to the mountain's table-top flatness is that it consists entirely of the very hard, lower layer of the Table Mountain Sandstone Formation. Originally this was topped by a thin glacial tillite layer, known as the Pakhuis Formation (see the diagram above, left), above which was the upper layer of Table Mountain Sandstone. Both these layers, but especially the tillite layer, are softer than the lower layer of Table Mountain Sandstone. When these softer layers eroded away, like a cream-topping on a cake, they left a very hard, flat erosion-resistant quartzitic sandstone platform behind which, today, forms Table Mountain's top.
Table Mountain is the northernmost end of a 50 km long, and roughly 6-10 km wide, Cape Fold Mountain range that forms the back bone of the Cape Peninsula, stretching from the Cape of Good Hope in the south to Table Mountain and its flanking Devil's Peak (to the east) and Lion's Head-Signal Hill (to the west) in the north. Table Mountain forms the highest point of this range. The range runs parallel to the other Cape Fold Mountain ranges on the mainland to the east.
FloraEdit
Table Mountain and the Back Table have an unusually rich biodiversity. Its vegetation consists predominantly of several different types of the unique and rich Cape fynbos. The main vegetation type is endangered Peninsula Sandstone Fynbos, but critically endangered Peninsula Granite Fynbos, Peninsula Shale Renosterveld and Afromontane forest occur in smaller portions on the mountain.
Table Mountain's vegetation types form part of the Cape Floral Region protected areas. These protected areas are a World Heritage Site, and an estimated 2,285 species of plants are confined to Table Mountain and the Cape Peninsula range, of which a great proportion, including many species of proteas, are endemic to these mountains and valleys and can be found nowhere else. Of the 2,285 species on the Peninsula 1,500 occur in the 57 km2 area comprising Table Mountain and the Back Table, a number at least a large as all the plant species in the whole of the United Kingdom. The Disa uniflora, despite its restricted range within the Western Cape, is relatively common in the perennially wet areas (waterfalls, streamlets and seeps) on Table Mountain and the Back Table, but hardly anywhere else on the Cape Peninsula. It is a very showy orchid that blooms from January to March on the Table Mountain Sandstone regions of the mountain. Although they are quite widespread on the Back Table, the best (most certain, and close-up) place to view these beautiful blooms is in the "Aqueduct" off the Smuts Track, halfway between Skeleton Gorge and Maclear's Beacon.
Remnant patches of indigenous forest persist in the wetter ravines. However, much of the indigenous forest was felled by the early European settlers for fuel for the lime kilns needed during the construction of the Castle. The exact extent of the original forests is unknown, though most of it was probably along the eastern slopes of Devil's Peak, Table Mountain and the Back Table where names such as Rondebosch, Kirstenbosch, Klassenbosch and Witteboomen survive (in Dutch "bosch" means forest; and "boomen" means trees). Hout Bay (in Dutch "hout" means wood) was another source of timber and fuel as the name suggests. In the early 1900s commercial pine plantations were planted on these slopes all the way from the Constantiaberg to the front of Devil's Peak, and even on top of the mountains, but these have now been largely cleared allowing fynbos to flourish in the regions where the indigenous Afromontane forests have not survived, or never existed.
Fynbos is a fire adapted vegetation, and providing fires are not too frequent, regular or intense, they are important drivers of fynbos diversity. Regular fires have dominated fynbos for at least the past 12 000 years largely as a result of human activity. In 1495 Vasco da Gama named the South African coastline Terra de Fume because of the smoke he saw from numerous fires. This was originally probably to maintain a productive stock of edible bulbs (especially watsonians) and to facilitate hunting, and later, after the arrival of pastoralists, to provide fresh grazing after the rains. Thus the plants that make up fynbos today are those that have been subjected to a variety of fire regimes over a very long period time, and their preservation now requires regular burning. The frequency of the fires obviously determines precisely which mix of plants will dominate any particular region, but intervals of 10-15 years between fires are considered to promote the proliferation of the larger Protea species, a rare local colony of which, the Aulax umbellata (Family: Proteaceae), was wiped out on the Peninsula by more frequent fires, as have been the silky-haired pincushion, Leucospermum vestitum, the red sugarbush, Protea grandiceps and Burchell's sugarbush, Protea burchellii, although a stand of a dozen or so plants has recently been "rediscovered" in the saddle between Table Mountain and Devil's Peak. Some bulbs may similarly have become extinct as a result a too rapid sequence of fires. The fires that occur on the mountains today are still largely due to unregulated human activity. Fire frequency is therefore a matter of chance rather than conservation.
Despite intensive conservation efforts the Table Mountain range has the highest concentration of threatened species of any continental area of equivalent size in the world. The non-urban areas of the Cape Peninsula (mainly on the mountains and mountain slopes) have suffered particularly under a massive onslaught of invasive alien plants for well over a century, with perhaps the worst invader being the cluster pine, partly because it was planted in extensive commercial plantations along the eastern slopes of the mountains, north of Muizenberg. Considerable efforts have been made to control the rapid spread of these invasive alien trees. Other invasive plants include black wattle, blackwood, Port Jackson and rooikrans (All Australian members of the acacia family), as well as several Hakea species and bramble.
FaunaEdit
The most common mammal on the mountain was the dassie (the South African name, from Afrikaans, pronounced "dussy"), or rock hyrax. Between about 2000 and 2004 (no one is certain about the exact year or years) their numbers suddenly plummeted for unknown reasons. They used to cluster around the restaurant at the upper cable station, near areas where tourists discarded or (inadvisably supplied) food. The population crash of the dassies was in all probability responsible for the decline in the Verreaux's eagle population on the Peninsula, which is believed to have consisted of 3 breeding pairs during the period 1950 to 1990, with only 2 pairs, maximally, ever having been reported to fledge a chick each in any given year. With the commencement of formal monitoring in 1993, two breeding pairs were recorded on the Cape Peninsula Mountain Chain in 2004: one below the upper cable station at the western end of Table Mountain, in Blinkwater Ravine, the other on the cliffs below Noordhoek Peak. The nest near the cable station was abandoned in 2006, leaving only the Noordhoek pair, which continued to fledge chicks reasonably regularly till 2013, at which point one member of the pair disappeared. From 2013 till January 2017 only a single Verreaux's Eagle, presumed to be a female, remained on the Peninsula. She continued to maintain the nest under Noordhoek Peak, but seemed unable to attract a mate. But in early 2017 a pair of eagles was seen by at least 7 independent observers during the course of 10 days (27 January - 5 February). It remains to be seen whether they will breed later in the year. Dassies are an important part the Verreaux's eagle's prey on the Peninsula. (See Foot note)
Table Mountain is also home to porcupines, mongooses, snakes, lizards, tortoises, and a rare endemic species of amphibian that is only found on Table Mountain, the Table Mountain ghost frog. The last lion in the area was shot circa 1802. Leopards persisted on the mountains until perhaps the 1920s but are now extinct locally. Two smaller, secretive, nocturnal carnivores, the rooikat (caracal) and the vaalboskat (also called the vaalkat or Southern African wildcat) were once common in the mountains and the mountain slopes. The rooikat continues to be seen on rare occasions by mountaineers but the status of the vaalboskat is uncertain. The mountain cliffs are home to several raptors species, apart from the Verreaux's eagle. They include the jackal buzzard, booted eagle (in summer), African harrier-hawk, peregrine falcon and the rock kestrel. In 2014 there were four pairs of African fish eagles on the Peninsula, but they nest in trees generally as far away from human habitation and activity as is possible on the Peninsula. Their numbers in 2017 is unknown.
Up until the late 1990s baboons occurred on all the mountains of the Peninsula, including the Back Table immediately behind Table Mountain. Since then they have abandoned Table Mountain and the Back Table, and only occur south of Constantia Nek. They have also abandoned the tops of many of the mountains, in favor of the lower slopes, particularly when these were covered in pine plantations which seemed to provide them with more, or higher quality food than the fynbos on the mountain tops. However these new haunts are also within easy reach of Cape Town's suburbs, which brings them into conflict with humans and dogs, and the risk of traffic accidents. There are now (2014) a dozen troops on the Peninsula, varying in size from 7 to over 100 individuals, scattered on the mountains from the Constantiaberg to Cape Point. The baboon troops are the subject of intense research into their physiology, genetics social interactions and habits. In addition, their sleeping sites are noted each evening, so that monitors armed with paint ball guns can stay with the troop all day, to ward them off from wandering into the suburbs. From when this initiative was started in 2009 the number of baboons on the Peninsula has increased from 350 to 450, and the number of baboons killed or injured by residents has decreased.
Himalayan tahrs, fugitive descendants of tahrs that escaped from Groote Schuur Zoo in 1936, used to be common on the less accessible upper parts of the mountain. As an exotic species, they were almost eradicated through a culling programme initiated by the South African National Parks to make way for the reintroduction of indigenous klipspringers. Until recently there were also small numbers of fallow deer of European origin and sambar deer from southeast Asia. These were mainly in the Rhodes Memorial area but during the 1960s they could be found as far afield as Signal Hill. These animals may still be seen occasionally despite efforts to eliminate or relocate them.
On the lower slopes of Devil's Peak, above Groote Schuur Hospital an animal camp bequeathed to the City of Cape Town by Cecil John Rhodes has been used in recent years as part of the Quagga Project. The quagga used to roam the Cape Peninsula, the Karoo and the Free State in large numbers, but were hunted to extinction during the early 1800s. The last quagga died in an Amsterdam zoo in 1883. In 1987 a project was launched by Reinhold Rau to back-breed the quagga, after it had been established, using mitochondrial DNA obtained from museum specimens, that the quagga was closely related to the plains zebra, and on 20 January 2005 a foal considered to be the first quagga-like individual because of a visible reduced striping, was born. These quagga-like zebras are officially known as Rau quaggas, as no one can be certain that they are anything more than quagga look-alikes. The animal camp above Groote Schuur Hospital has several good looking Rau quaggas, but they are unfortunately not easily seen except from within the game camp, which is quite large and undulating, and the animals are few. The animal camp is not open to the public.
HistoryEdit
Prehistoric inhabitation of the district is well attested (see for example the article on Fish Hoek). About 2000 years ago the Khoikhoi migrated towards the Cape Peninsula from the north, displacing the San and bringing with them their herds of cattle and sheep. It was the Khoikhoi who were the dominant local tribe when the Europeans first sailed into Table Bay.
António de Saldanha was the first European to land in Table Bay. He climbed the mighty mountain in 1503 and named it Taboa do Cabo (Table of the Cape, in his native Portuguese). The great cross that the Portuguese navigator carved into the rock of Lion's Head is still traceable.
In 1796, during the British occupation of the Cape, Major-General Sir James Craig ordered three blockhouses to be built on Table Mountain: the King's blockhouse, Duke of York blockhouse (later renamed Queen's blockhouse) and the Prince of Wales blockhouse. Two of these are in ruins today, but the King's blockhouse is still in good condition. and easily accessible from the Rhodes Memorial.
Between 1896 and 1907, five dams, the Woodhead, Hely-Hutchinson, De Villiers, Alexandria and Victoria reservoirs, were opened on the Back Table to supply Cape Town's water needs. A ropeway ascending from Camps Bay via Kasteelspoort ravine was used to ferry materials and manpower (the anchor points at the old top station can still be seen). There is a well-preserved steam locomotive from this period housed in the Waterworks Museum at the top of the mountain near the Hely-Hutchinson dam. It had been used to haul materials for the dam across the flat top of the mountain. Cape Town's water requirements have since far outpaced the capacity of the dams and they are no longer an important part of the water supply.
Arguments for a national park on the Cape Peninsula, centred on Table Mountain, began in earnest in the mid-1930s. Following a big fire in 1986, the Cape Times started a 'save the mountain' campaign, and in 1989 the Cape Peninsula Protected Natural Environment (CPPNE) area was established. However, environmental management was still bedeviled by the fragmented nature of land ownership on the Peninsula. Following another big fire in 1991, Attorney General Frank Kahn was appointed to reach consensus on a plan for rationalizing management of the CPPNE. In 1995, Prof. Brian Huntley recommended that SANParks be appointed to manage the CPPNE, with an agreement signed in April 1998 to transfer around 39,500 acres to SANParks. On 29 May 1998, then-president Nelson Mandela proclaimed the Cape Peninsula National Park. The park was later renamed to the Table Mountain National Park.
Fires are common on the mountain. The most recent major fires include those of January 2006, which burned large amounts of vegetation and resulted in the death of a tourist (a charge of arson and culpable homicide was laid against a British man who was suspected of starting the blaze), and March 2015.
In November 2011, Table Mountain was named one of the new seven wonders according to votes received, but the official result of the new natural wonders are still to be presented to the world by the New7Wonders of the World.
CablewayEdit
The Table Mountain Cableway takes passengers from the lower cable station on Tafelberg Road, about 302 m above sea level, to the plateau at the top of the mountain, at 1067 m. The upper cable station offers views overlooking Cape Town, Table Bay and Robben Island to the north, and the Atlantic seaboard to the west and south.
Construction of the cableway was first started in 1926, and the cableway was officially opened in 1929. In 1997, the cableway was extensively upgraded, and new cars were introduced carrying 65 instead of 25 passengers. The new cars give a faster journey to the summit, and rotate through 360 degrees during the ascent or descent, giving a panoramic view over the city.
The top cable station offers viewpoints, curio shops, a restaurant and walking trails of various lengths.
ActivitiesEdit
Hiking on Table MountainEdit
Hiking on Table Mountain is popular amongst locals and tourists, and a number of trails of varying difficulty are available. Because of the steep cliffs around the summit, direct ascents from the city side are limited. Platteklip Gorge, a prominent gorge up the centre of the main table, is a popular and straightforward direct ascent to the summit. Par for the course is about 2.5 hours but is done between 1-3 hours depending on one's fitness level. This route is very hot in summer, as it is located on the north facing slope of the mountain, with almost no shade along the 600 m climb from Tafelberg Road to the Table Mountain plateau.
Longer routes to the summit go via the Back Table, a lower area of Table Mountain to the south of the main, northern, plateau (which constitutes "Table Mountain" as seen from the Cape Town City Centre and Table Bay). From the Southern Suburbs side, the Nursery Ravine and Skeleton Gorge routes start at Kirstenbosch National Botanical Garden. The route via Skeleton Gorge to Maclear's Beacon is known as Smuts Track in memory of Jan Smuts, who was a keen hiker. The Bridle Path, or Jeep Track, makes a more gradual ascent from Constantia Nek along the road used to service the dams on Back Table. There are many other paths in popular walking areas on the lower slopes of the mountain accessed from Constantia Nek, Cecilia Park, Kirstenbosch, Newlands Forest and Rhodes Memorial.
On the Atlantic side, the most popular ascent is Kasteelspoort, a gorge overlooking Camps Bay, but there are a few others, but not as many as on the east side of the mountain.
There is a popular "Contour Path" that runs from Constantia Nek, and then, in succession, above Cecilia Park, Kirstenbosch Botanical Gardens, Newlands Forest, and from there, above Groote Schuur Estate, past the King's Blockhouse, at the north-east corner of Devil's Peak, immediately below the Mowbray Ridge cliffs, to the front of Devil's Peak and the north face of Table Mountain, ending at the bottom of Kloof Corner Ridge at the western end of the Table Mountain cliffs. It starts at Constantia Nek at 250 m, but immediately gradually climbs to around 320 m at Angela's Memorial and the look-out point above Cecilia Park. It then undulates down and up again at about this elevation as far the north-western corner of Kirstenbosch, when the path suddenly climbs quite steeply to 470 m to the scree (or Dassieklip) below the cliffs of Fernwood Buttress. It then descends again to 350 m, only to ascend again to 400 m, 1 km later. It remains at this level, as a true 'contour path', to the King's Blockhouse, and from there, eventually, to Tafelberg Road (at 400 m). From the King's Blockhouse it is possible to choose a footpath that will lead to the "upper contour path" which traverses the front (north face) of Devil's Peak and Table Mountain at 500 m, to just beyond the Lower Cable Station. From there it is possible, from either contour path, to join up with the "Pipe Track" which starts from Kloof Nek, and then runs at an elevation of about 300 m, below the cliffs of the Twelve Apostles, on the Atlantic side of the mountain range as far as the Oudekraal Ravine, where the path goes up the ravine to join the "Apostles Path" on top of the Back Table at an elevation of 685 m. There are innumerable paths which join the contour path from below (at least five from Kirstenbosch alone), and somewhat fewer that join it from above.
On top of the mountain, and particularly on the Back Table, there is an extensive network of well marked footpaths offering hiking opportunities over a wide variety of terrains, and distances which can be covered in 30 minutes to several hours (or even all day if so desired). Good maps of all the routes are available at bookshops and outdoor recreation stores, which hikers are advised to use, as dense mist and cold weather (or extreme heat) can descend without warning at any time of the year.
The Hoerikwaggo Trails were four hiking trails on the Cape Peninsula Mountain Chain ranging from two to six days, operated by South African National Parks (SANPARKS) between the Victoria & Alfred Waterfront and Cape Point. Today (2017) the trails can no longer be undertaken with an official SANPARKS guide, and only four of the original accommodation facilities are operational (the Overseer's Cottage on the Back Table, the Orange Kloof Tented Camp, the Slangkop Tented Camp and the Smitswinkel Tented Camp). These camps are "self-catering", each with communal ablution facilities, with large communal kitchen/lounge areas, fully equipped for 12 persons. SANPARKS arranges for luggage and provisions to be transported to the operational cottages and tented camps, so that the hikers can ascend the mountain unencumbered by heavy backpacks.
The original inhabitants of the area, the Khoekhoen and San tribes, called Table Mountain Hoerikwaggo - "sea mountain". The four Table Mountain Hoerikwaggo hiking trails were called the People's Trail, Table Mountain Trail, Orangekloof Hiking Trail and Top to Tip Trail.
Rock climbingEdit
Rock climbing on Table Mountain is a very popular pastime. There are well-documented climbing routes of varying degrees of difficulty up the many faces of the mountain. The main climbs are located on cliffs below the upper cable station. No bolting can be done here and only traditional climbing is allowed. Commercial groups also offer abseiling from the upper cable station.
CavingEdit
Most of the world's important caves occur in limestone but Table Mountain is unusual in having several large cave systems that have developed in sandstone. The biggest systems are the Wynberg Caves, located on the Back Table, not far from the Jeep Track, in ridges overlooking Orange Kloof and Hout Bay.
Mountain bikingEdit
The slopes of Table Mountain have many jeep tracks that allow mountain biking. The route to the Block House is a popular route for bike riding. Plum Pudding Hill is the name of a very steep jeep track. Bike riders should follow the directional signs on display for mountain bike riders.
"Mensa" constellationEdit
Table Mountain is the only terrestrial feature to give its name to a constellation: Mensa, meaning The Table. The constellation is seen in the Southern Hemisphere, below Orion, around midnight in mid-July. It was named by the French astronomer Nicolas de Lacaille during his stay at the Cape in the mid-18th century.
