How do I get to the Cook IslandsWhere do I get to the Cook Islands?
The Aitutaki is partly vulcanic, partly igneous; it is also referred to as near-atoll.
Mauke, Mitiaro, Atiu, Takutea, Manuae, the Eclipse Sea-mount (between Manuae and Aitutaki), Aitutaki and after a small hollow Palmerston are forming a straight line of volcanoes with a Wnw-tendency. The Rarotonga and Mangaia are on the ridge of a seperate arc that surrounds the Mauke-Aitutaki-Chains. It is likely that Rarotonga is due to crust-like reactions to the further decline of the group.
There was a new body of water around her below see surface. This elevated crag that surrounds the ascending summits is known as the macatea. These four islands are elevated islands of corals or macatea. Situated between the Manihiki Plateau and the Line Islands, the highest of the Cooks' volcanoes, it has a topography of over 4,876 metres.
Niue, once within the Cook Islands' borders (1901/3), is not one of the Southern Cook-mountains. This is an insulated islet of corals near the top of the Tongan Trench, made entirely of lime and covering a sunken vulcano. The volcanos of the group in the north are thought to have been high above the surface at this time.
Oligocene (38 to 26 million years ago) and Miocene (26 to 7 million years ago) were found in the elevated Mangaia sea wall page 66 Penrhyn, Manihiki-Rakahanga and Suwarrow are supported by 14 to 22 million year old limestones (Miocene). Atiu' s endemic freshwater life began in the early Pliocene (7 million years ago), while the reefs of Suwarrow, Rakahanga, Pukapuka (south of Ngake) and Manihiki (south of Tauhunu) probably date back to the Pleistocene (2 million and fewer years ago).
Mangaia at plus 2m showed a radius of 90 plus/minus 20 and 110 plus/minus 20,000 years. Ngatangiia's macatea, Rarotonga, can have a similar population. Rarotonga and Aitutaki's most important coral formations were built before the last glacial period (15,000 years ago). An elevated Avarua Rarotanga with plus 1 meter above the low tide was dating to 2,130 BC (before the present), while the near-by Rarotonga with plus 2 meters is older than 43,000 BC. Rarotonga is the youngest of the Cook people.
