Table Mountain (Afrikaans: Tafelberg) is a flat-topped mountain forming a prominent landmark overlooking the city of Cape Town in South Africa, and is featured in the Flag of Cape Town and other local government insignia.[2] 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.

Features[edit]

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, 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.[3]

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.[4] 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. To the south of the main plateau is a lower part of the range called the Back Table. On the Atlantic coast of the peninsula, the range is known as the Twelve Apostles. The range continues southwards to Cape Point.

Geology[edit]

Main article: Cape Fold Mountains
Geology of Table Mountain in relation to the geology of the rest of the Cape Peninsula.

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.[6][7] The uppermost, and younger of the two layers, consists of extremely hard quartzitic sandstone, commonly referred to as Table Mountain Sandstone (TMS), 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.[6] 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.[6][8] The overlying TMS probably arose in deeper water, either as a result of subsidence, or a rise in the sea level.[6][8] 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.[6]

An west-east (left to right) geological cross section through Table Mountain on the Cape Peninsula, the Cape Flats (the isthmus connecting the Peninsula to the African mainland) and the Hottentots-Holland Mountains on the mainland. It indicates how the Cape Fold Mountains have been eroded in this region, leaving what was once the bottom of a valley to form Table Mountain with its flat table-top structure.[6]

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).[6][9][10] 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".[6]

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.

Flora[edit]

Table Mountain has 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.

The mountain's vegetation types form part of the Cape Floral Region protected areas. These protected areas are a World Heritage Site, and an estimated 2,200 species of plants are confined to Table Mountain - more than exist in the whole of the United Kingdom.[11][12] Many of these species, including a great many types of proteas, are endemic to the mountain and can be found nowhere else.

In addition, the Table Mountain range has the highest concentration of threatened species of any continental area of equivalent size in the world.[13]

Remnant patches of indigenous forest persist in the wetter ravines. However, much of the indigenous forest has been felled and replaced with commercial plantations. Varieties of fynbos tend to dominate on the more exposed parts of the mountain (such as above the city) where conditions are too dry and harsh for forests. The mountain's natural wildfire cycle seasonally burns and thus rejuvenates the fynbos vegetation on these exposed slopes.[14][15]

The mountain has also suffered under a massive onslaught of invasive alien plants for well over a century, with perhaps the worst invader being the cluster pine. Considerable efforts have been made to control the rapid spread of these invasive alien trees. Other invasive plants include Wattle, Port Jackson and Rooikrans (All Australian members of the Acacia family).[16]

Dassies (rock hyrax)

Fauna[edit]

The most common mammal on the mountain was the dassie, 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 upper cable station, near areas where tourists discarded or (illegally) supplied food. The population crash of the dassies has in all probability been responsible for the decline in the Verreaux's eagle population on the Peninsula, which currently (2014) consists of only one nesting pair on Noordhoek Peak, when previously there had been at least three pairs, one of which had a cliff nest near the upper cable station on Table Mountain, in Blinkwater Ravine. Dassies were an important part the Verreaux's Eagles' prey on the Peninsula.[17] Table Mountain is also home to porcupines, mongooses, snakes, lizards, tortoises, and an 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 mountain 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 African wild cat) were once common on the mountain. 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.[17]

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.[18][19] 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.[19]

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.[20] 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 zebra are officially known as Rau quagga, 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 in not open to the public.

History[edit]

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.[21][22][23] 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.

The mountain became part of the new Cape Peninsula National Park in the 1990s. The park was renamed to the Table Mountain National Park in 1998.

Fires are common on the mountain. The most recent major fire came in January 2006, destroying large amounts of vegetation and resulting 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.

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.[24]

Cableway[edit]

Table Mountain Aerial Cable Car

The Table Mountain Cableway[25] 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. 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.

Activities[edit]

Hiking on Table Mountain[edit]

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.

Longer routes to the summit go via the Back Table, a lower area of Table Mountain to the South of the main plateau. 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, while the Pipe Track is a level route popular with walkers.

The Hoerikwaggo Trails[26] are four hiking trails on Table Mountain ranging from two to six days, operated by South African National Parks. The original inhabitants of the area, the Khoekhoen and San tribes called Table Mountain Hoerikwaggo – "sea mountain". The four Table Mountain hiking trails are called the People's Trail, Table Mountain Trail, Orangekloof Hiking Trail and Top to Tip Trail.[27]

Rock climbing[edit]

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.

Caving[edit]

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 Biking[edit]

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 is the name of a very steep jeep track. Bike riders should follow the directional signs on display for mountain bike riders.

"Mensa" constellation[edit]

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.[citation needed]
