The Moeraki Boulders are a big attraction, found on Koekohe Beach near Moeraki on New Zealand’s coast. The huge, gray, spherical stones formed in sediment on the sea floor 60 million years ago and were revealed by shoreline erosion. The boulders, some of which stand alone and some in clusters, can weigh several tons and measure 10 feet across. >>> Pretty neat, has anyone seen these?
