Svenja Arlt's DPhil project addresses patterns of fine-scale spatial and temporal variation of the Robberg Complex in the Caledon River Valley in southern Africa. The Robberg is a miniaturised technocomplex from the beginning of the southern African Later Stone Age with an emphasis on the production of elongated, parallel-sided slivers of stone, known archaeologically as bladelets. Ntloana Tšoana and the nearby sites of Ha Makotoko and Rose Cottage Cave were all inhabited during the last phase of the Robberg, c. 16,500-10,500 years before today. By analysing the stone artefacts from these three sites, I am investigating how people coped with the climatically variable conditions of the Pleistocene-Holocene transition in the Caledon River Valley.
