Wonderwerk Cave is an archaeological site, formed originally as an ancient solution cavity in dolomite rocks of the Kuruman Hills, situated between Danielskuil and Kuruman in the Northern Cape Province, South Africa. It is a National Heritage Site, managed as a satellite of the McGregor Museum in Kimberley. Geologically, hillside erosion exposed the northern end of the cavity, which extends horizontally for about 140 m (460 ft) into the base of a hill. Accumulated deposits inside the cave, up to 7 m (23 ft) in-depth, reflect natural sedimentation processes such as water and wind deposition as well as the activities of animals, birds, and human ancestors over some 2 million years. The site has been studied and excavated by archaeologists since the 1940s and research here generates important insights into human history in the subcontinent of Southern Africa. Evidence within Wonderwerk cave has been called the oldest controlled fire. Wonderwerk means "miracle" in the Afrikaans language. Source: Wikipedia (en)
