This complex of caves is known world-wide for the very ancient archaeological deposits that accumulated for more than 100 000 years against the cliff face of the Tsitsikamma coastline. Their systematic excavation and analysis have yielded an array of vertebrate faunal remains, hundreds of stone artefacts, large amounts of marine shells and the superimposed series of hearth features left by people during the Middle Stone Age. Along with these, the recovery of a few and unique fragmentary human remains has helped scientists understand the development modern people as we know it today in terms of human anatomy and behaviour.
