Moeraki Boulders facts for kids
The Moeraki Boulders are amazing, giant, round rocks found on Koekohe Beach in New Zealand. You can see them along the Otago coast, between the towns of Moeraki and Hampden. Some of these huge boulders are grouped together, while others stand alone on the sand. This special area is protected as a scientific reserve, meaning it's kept safe for everyone to enjoy and learn from.

What Are the Moeraki Boulders?
The Moeraki Boulders are not just any rocks; they are spherical (meaning perfectly round) and very large. They formed inside a type of soft rock called mudstone. Over many years, the ocean waves crash against the coast, slowly wearing away the mudstone. As the mudstone washes away, the hard, round boulders are left behind, sitting exposed on the sandy beach.
How Did These Giant Boulders Form?
These unique boulders started forming millions of years ago, deep under the sea. They grew slowly, bit by bit, like a pearl grows inside an oyster. Minerals in the ancient mudstone gathered around a tiny piece of shell or fossil, gradually building up layers to create the round shapes we see today. This process is called "concretion."
Māori Legends About the Boulders
The local Māori have a wonderful legend about how the Moeraki Boulders came to be. They say the boulders are the remains of a large sailing canoe called the Arai-te-uru, which was shipwrecked long ago. According to the story, the boulders are actually eel baskets, calabashes (gourds for carrying water), and kumara (sweet potatoes) that washed ashore from the wrecked canoe.
The legend also says that the rocks stretching out into the sea from Shag Point are the petrified (turned to stone) hull of the canoe itself. And a nearby rocky point is believed to be the body of the canoe's captain. These stories help us understand the deep connection Māori people have with their land and its natural wonders.
History and Popularity
People have known about the Moeraki Boulders for a very long time. In 1848, a drawing of the beach showed even more boulders than there are today. This old picture is now kept safe in the Alexander Turnbull Library in Wellington.
Since the 1850s, the boulders have been written about in many reports and articles. In more recent times, they have become a very popular tourist attraction. Many web pages and travel guides feature pictures and descriptions of these amazing rocks, drawing visitors from all over the world to see them. It's a great place to visit and learn about geology and Māori culture!
