Field WorkCountry: South Africa
Day: 1 - Cape Town - Friday, 28 March
We will start from Signal Hill for an overview from Dr. John Compton, associate professor of geological sciences at the University of Cape Town. Next, we’ll proceed to Sea Point, a site made famous by Charles Darwin’s 1836 visit and its role in the early history of geology, to examine a mix of sedimentary rocks and granite exposed along the coast. We will then drive south to Hout Bay and drive along the spectacular Chapman’s Peak Drive to view granite and sandstone cliffs. We will go all the way to the southwestern most tip of Africa, the Cape of Good Hope and to the Cape Point lighthouse. Coming back along the False Bay coast we will stop to observe a penguin colony at Boulder Beach. Academic Objectives:
- Observe and record (in writing and photographs) the diversity of both the natural coastal landforms (granitic headlands, long sandy beaches, dunes and estuaries, offshore islands) around the Western Cape.
- Document and describe the factors and coastal processes that have shaped this section of the Cape Town coastline.
- Relate the fossil record to the last 5 million years of sea level and environmental change.
