Wonderwerk Cave

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 into the base of a hill. Accumulated deposits inside the cave, up to 7 m in depth, reflect natural sedimentation processes such as water and wind deposition as well as the activities of animals, birds and human ancestors over a period of 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.

The cave contains up to 6 m depth of archaeological deposits reflecting human and environmental history through the Earlier, Middle and Later Stone Ages to the present. Cosmogenic dating suggests that basal sediment entered the cave some 2 million years ago. Rock art occurs in the form of parietal paintings within the first 40 metres from the entrance, possibly all less than 1000 years old, and small engraved stones found within the deposit, mainly from the Later Stone Age sequence where they date back some 10 500 years. The associations of older engraved or striated pieces have yet to be substantiated.

Major damage was caused in the 1940s when local farmers dug up large parts of the cave interior to bag and sell organic-rich material as fertiliser – which in fact comprised stratified archaeological deposits containing artefacts, bone and other material that would have been crucial to an understanding of the cultural and palaeoenvironmental history of the site. The presence of bone was reported upon, leading to the first archaeological and zooarchaeological investigations.

The initial archaeological studies of the 1940s, by Malan, Cooke and Wells, were followed up briefly by K.W. Butzer in the 1970s.Peter Beaumont of the McGregor Museum in Kimberley then carried out major excavations at the site between 1978 and 1993, with Anne Thackeray and Francis Thackeray working at the site in 1979, excavating and researching the Later Stone Age levels from cultural and archaeozoological perspectives respectively. Current work is being led by Prof Michael Chazan of the University of Toronto, Dr. Liora Kolska Horwitz of the The Hebrew University and Dr. Francesco Berna Simon Fraser University in collaboration with the McGregor Museum (where excavated assemblages are housed). A digital model of the site was created by laser scanning, forming part of the Zamani Project. Key team members who have worked on the dating of the lower units are the late Hagai Ron (magnetostratigraphic or palaeomagnetic dating), Ari Matmon (cosmogenic isotope dating), Robyn Pickering (U/Pb dating) and Naomi Porat (Optically stimulated luminescence dating). Results of these archaeological, dating, sedimentological and palaeoenvironmental studies were first reported at a symposium convened by Chazan and Horwitz at the site. They have since been published in a series of papers, and in a special issue on the site published in 2015 in
