The Three Roots
Mitiaro makes up part of an island grouping called Nga-Pu-Toru. or "The Three Roots". The other two are Atiu and Mauke. It's the flattest and economically, the poorest. Like the other two, it was once a volcano that sank to become a coral atoll. It was also thrust upwards 10,000 years ago, but unlike the others, it only rose about 20 feet. Despite that, its coral ring still died forming the makatea.
