Celebrating International Mountain Day with The Cableway

Celebrating International Mountain Day with The Cableway

To celebrate International Mountain Day on Monday 11 December, Table Mountain Cableway, in partnership with the Geological Society of South Africa, has put together an infographic revealing the geological secrets of the 260 million year old Cape Town icon.

The infographic, on public display at the Upper Cable Station, reveals the four different rock layers which constitute the structure of Table Mountain:

  • Cape Granite – Hard and coarse-grained, this rock is the foundation for most of Table Mountain. It is characterised by large white feldspar crystals, shimmering flakes of black mica and grey glassy quartz.
  • Malmesbury Group – Around 540 million years old, this formation that forms the foundation of Devil’s Peak consists of siltstone, mudstone and lighter coloured sandstones.
  • Graafwater Formation – Between 25m and 65m thick, this reddish brown layer of sandstone and siltstone is the mountain’s middle layer and its thinnest.
  • Peninsula Formation – Comprised of light grey, pebbly sandstones, this formation, at 700m thick, is the top layer and forms the bulk of Table Mountain.

Some other lesser-known facts about Table Mountain:

  • It is approximately 260-million years old.
  • It is part of the Cape Floristic Region World Heritage Site, with Table Mountain National Park being home to an incredible 8200 plant species – of which 80% are Fynbos.
  • At its highest point (Maclear’s Beacon), Table Mountain sits at 1067m above sea level.
  • Table Mountain is neighboured by Devil's Peak at 1000m above sea level, and Lion’s Head at 669m above sea level.
  • Table Mountain is referred to as Hoerikwaggo meaning “Mountain of the Sea” by the Khoikhoi.
