Middens are present throughout the entire coastal and inland area, and clearly visible in dunefields and inland of the rocky stretch of coast between the Cape St Francis Point and St Francis Bay. The wind is a very active erosive agent, constantly exposing and recovering the middens. Fish-traps are found in Oyster Bay with more middens and hearths around the Slang River. Standloper pottery can still be found around these middens.
Cape St Francis is situated on approximately 4,8km either side of a headland which is capped by two rocky promontories (Cape St Francis Point and Seal Point), a unique occurrence in the world.
