Sensational Rock Formations: Moeraki Boulders

The Moeraki Boulders are unusually large and spherical boulders lying along a stretch of Koekohe Beach on the wave cut Otago coast of New Zealand between Moeraki and Hampden. They occur scattered either as isolated or clusters of boulders within a stretch of beach where they have been protected in a scientific reserve.

The erosion by wave action of mudstone, comprising local bedrock and landslides, frequently exposes embedded isolated boulders. Take a look at hese boulders have been exhumed from the mudstone enclosing them and concentrated on the beach by coastal erosion.
