More Information
Summary:Mangaia is the most southerly of the Cook Islands with a land area of 52 square kilometres. It comprises the highly weathered remains of a volcanic cone that emerged from the Pacific some 20 million years ago and stands 15,600 feet (4,750 metres) above the ocean floor. In the late Pleistocene epoch, tectonic activity resulted in the elevation of the island and reef. Subsequent undercutting of the elevated reef by run off from the former volcanic core has helped create the current formation of the limestonemakateawhich surrounds the island, standing up to 200 feet (60 metres) above sea
