Approximately 60 hectares in areas, on the foreshore between Maslin Beach and Aldinga Beach, the area contains excellent and rare exposures of the older Cainozoic (up to 65 million years old) sediments of the Adelaide region. Sandy Beach deposits and rock debris from the cliffs above form a shore section about 100m wide with the outcrop about 5km in length. It has been been subject to scientific studies since 1878 and is an important reference area for secondary and tertiary teaching in geology.
