The Witwatersrand is a prominent geological ridge located in South Africa, known for its rich deposits of gold. This area played a crucial role in the country's mining industry, particularly during the late 19th and early 20th centuries, when gold was discovered, leading to a significant economic boom and the establishment of cities like Johannesburg. The ridge stretches approximately 56 kilometers and is situated in the Gauteng province. It is not only important for its mineral wealth but also for its historical significance, as it attracted a large influx of people during the Gold Rush, shaping the demographics and economy of the region.
