The Moeraki Boulders are large, spherical concretions formed from mudstone, a type of sedimentary rock, approximately 60 million years ago during the Paleocene era. These boulders, which can reach up to 3 meters in diameter and 7 tons in weight, were created through a process of sedimentation and mineralization on the seafloor, and were later exposed by coastal erosion along Koekohe Beach. Optimal time for photography is during mid-tide which required an early departure from Dunedin. We drove through rain for much of the way but it stopped as we arrived in Moeraki only to start again after I captured my final images. This good fortune did not persist, however, as rain and low clouds greeted us as when we arrived at Aoraki / Mount Cook later in the day.
