Table Mountain


Table Mountain
Table Mountain 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.


Geology

The upper part of the mountain mesa consists of Ordovician quartzitic sandstone, commonly referred to as Table Mountain Sandstone (TMS), which is highly resistant to erosion and forms characteristic steep grey crags. Below the sandstone is a layer of micaceous basal shale, which weathers quite readily and is therefore not well exposed. The basement consists of heavily folded and altered phyllites and hornfelses known informally as the Malmesbury shale. This has been intruded by the Cape Granite. Both rocks are of late Precambrian age. 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.

History

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 'Table Mountain' ('Montanha da Mesa' in 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.

Hiking

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 Maclears 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 Forest, 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 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.
