Most of the famous moai or monolithic sculptures found on Easter Island (Rapa Nui) were carved in hard volcanic tuff quarried around the edge of and inside the crater of Rano Raraku. Nearly 400 moai remain in the quarries and these allow the stage of production of these statues to be reconstructed. More
