Dit is ongelooflik mooi om daar bo te staan en die natuurwonder te aanskou.
Separated by around 300 metres of water, The Knysna Heads are the headlands of two peninsulas that enclose and form the Knysna River Estuary. Formed over geological time beginning as far back as the break-up of the supercontinent, Gondwana, during the Jurassic, 180 million years ago. the Knysna Heads can be described as the rocky headlands at the western and eastern ends of the two peninsulas that embrace and define the Knysna basin. They also frame the Knysna Estuary’s only entrance to the sea.
How The Knysna Heads were formed:
The Peninsula Formation quartzites visible at Coney Glen - the beach on the Eastern Head - exhibit intensely fractured breccia zones (faults) and similarly-orientated jointing that lie in a northwest-southeast direction. This deformation is related to the formation of the Knysna half-graben faulting that occurred during the break-up of the supercontinent, Gondwana.
Rivers will naturally exploit zones of weakness in the underlying geology, and the slow-flowing Knysna River, meandering across the coastal plain, will have eroded downwards through the intensely fractured quartzite at the same pace as the coast gradually uplifted (this Tertiary Period uplift, which raised the level of the coast by some 500 meters, began 60 million years ago, and ended about 5 million years ago).
The Heads were therefore formed when the Knysna River cut a channel through a ridge of hard Peninsula Formation quartzite (commonly known as TMS, or Table Mountain Sandstone).
The Knysna River mouth
Commonly known as The Heads, the Knysna River mouth is about 230 metres wide.
