Abstract
Cape Hangklip consists of the abrasion platform of the 60 Foot Sea, partially regraded at the 20–25 Foot Stage and at the 12–14 Foot Sub-stage of the succeeding regression. A basal shingle may be evidence of this marine withdrawal. In its upper parts, the platform was buried by peat which formed towards the close of the Early Stone Age. A succeeding Middle Stone Age occupation level was buried by sand-dunes advancing from the south and east. With the erosion of the sand-dunes and the resumption of normal drainage the peat has been extensively removed. Farther south, the platform consisted of isolated rock banks which were joined together and to the mainland by shingle beaches. These beaches are attributed to a sea standing 6 feet above present sea-level and are tentatively correlated with the marine re-advance following the last Pleistocene regression. They antedate the dune system. The beaches and dunes are capped by shell middens with a predominantly ‘Strandloper’ cultural assemblage.
