Table Mountain

Table Mountain (known in Khoekhoe as Huriǂoaxa, meaning "sea-emerging," and in Afrikaans as Tafelberg) is a flat-topped mountain that stands as a defining landmark above Cape Town, South Africa. It draws many tourists, who reach the summit either by cableway or on foot. The mountain hosts 2,285 plant species, with roughly 80% being fynbos (Afrikaans for "fine bush"). Table Mountain National Park, the most visited national park in South Africa, welcomes 4.2 million people each year for a range of activities. This area was once home to Khoe-speaking clans, including the !Uriǁʼaes, or "High Clan." The mountain supports a wide variety of mostly endemic plants and animals. Its summit rises about 1,000 meters above the city, making the popular hike—along numerous steep, rocky paths—a serious undertaking that demands fitness, preparation, and proper gear.

The mountain’s defining feature is its level plateau, roughly three kilometers wide, edged by steep cliffs. Flanked by Devil’s Peak to the east and Lion’s Head to the west, the plateau forms a dramatic backdrop to Cape Town. Together with Signal Hill, these heights create the natural amphitheater of the City Bowl and Table Bay harbour. The highest point, near the plateau’s eastern end, is marked by Maclear’s Beacon, a stone cairn built in 1865 by Sir Thomas Maclear for trigonometrical survey. It sits 1,086 meters above sea level, about 19 meters higher than the cable station at the plateau’s western end. The cliffs are split by Platteklip Gorge ("Flat Stone Gorge"), offering a direct and relatively easy ascent; António de Saldanha took this route during the first recorded climb of the mountain in 1503. The flat top is often shrouded in orographic clouds, formed when a southeasterly wind pushes moist air up the slopes into colder air, creating the "table cloth." Legend says this results from a smoking contest between the Devil and a local pirate named Van Hunks, and the cloud’s appearance symbolizes that contest.

Table Mountain sits at the northern end of a sandstone mountain range that runs the length of the Cape Peninsula, ending about 50 kilometers south at the Cape of Good Hope and Cape Point. Just south of Table Mountain lies a rugged, lower plateau called the "Back Table," roughly 1,000 meters high, which extends about 6 kilometers to the Constantia Nek–Hout Bay valley. The Atlantic side of the Back Table is known as the Twelve Apostles, stretching from Kloof Nek (the saddle between Table Mountain and Lion’s Head) to Hout Bay. The eastern side, from Devil’s Peak and the eastern buttresses of Table Mountain to Constantia Nek, has no single name but is recognized by the conservation areas on its lower slopes: Groote Schuur Estate, Newlands Forest, Kirstenbosch Botanical Gardens, Cecilia Park, and Constantia Nek.

Geologically, the upper 600 meters of the mountain consists of 450- to 510-million-year-old Ordovician rocks from the two lowest layers of the Cape Fold Mountains. The topmost, younger layer is hard quartzitic sandstone, called "Table Mountain Sandstone" (TMS) or "Peninsula Formation Sandstone," which resists erosion and forms steep grey crags. Below it, a 70-meter-thick layer known as the "Graafwater Formation" is made of maroon mudstones laid down in thinner horizontal strata. These Graafwater rocks are visible just above the contour path on the mountain’s front and around Devil’s Peak, as well as in the cutting along Chapman’s Peak Drive. They likely formed in shallow tidal flats, where a few Ordovician fossils and tracks have been preserved. The overlying TMS probably formed in deeper water, due to subsidence or a rise in sea level. The Graafwater rocks rest on a basement of Cape Granite. Devil’s Peak, Signal Hill, the City Bowl, and much of the Cape Flats sit on folded and altered phyllites and hornfelses, informally called Malmesbury shales. The Cape Granite and Malmesbury shales form the lower, gentler slopes of the Table Mountain range on the Peninsula. They date to the late Precambrian, at least 40 million years older than the Graafwater rocks.

The basement rocks are less resistant to weathering than TMS, but large outcrops of Cape Granite appear on the western side of Lion’s Head and elsewhere on the Peninsula, such as below Chapman’s Peak Drive and at The Boulders near Simon’s Town. The weathered granite soil on the lower slopes is more fertile than the nutrient-poor TMS soil, so most vineyards on the Cape Peninsula are found on these granitic slopes. The mountain’s flat top results from its being a syncline mountain—originally the floor of a valley. The anticline, or highest point of the folds that once included Table Mountain, lay to the east but has since weathered away.
