Sleeping Moai, Easter Island Editorial Image

Rano Raraku is a volcanic crater formed of consolidated volcanic ash, or tuff, and located on the lower slopes of Terevaka in the Rapa Nui National Park on Easter Island in Chile. It was a quarry for about 500 years until the early eighteenth century, and supplied the stone from which about 95% of the island`s known monolithic sculptures moai were carved. Rano Raraku is a visual record of moai design vocabulary and technological innovation.
