Geological marvels

The Moeraki Boulders are a group of large spherical “stones” on Koekohe Beach near Moeraki on New Zealand’s Otago coast. These boulders are actually concretions that have been exposed through shoreline erosion from coastal cliffs. Even today, there are still boulders remaining in the mudstone that will, eventually, fall on to the beach as they come lose due to erosion! (…) There are over 50 boulders along Koekohe Beach. The biggest boulders weigh 7 tons and measure over 2 metres across. It took about 4 million years for the largest boulders to form to their current size.1 The tiny fragments however began forming about 60 million years ago.” –

The Moeraki Boulders are indeed quite something when you see so many of them scattered all over the beach! I’ve never seen anything like this and it’s fascinating to read how old they really are!
