"This Moai has great potential for scientific and natural studies, it's a really unique discovery as it's the first time that that a Moai has been discovered inside a laguna in a Rano Raraku crater," said the Ma'u Henua Indigenous community in a statement on Tuesday. "The interesting thing is that, for at least the last 200 or 300 years, the laguna was three meters deep, meaning no human being could have left the moai there in that time," said Huki, who is also the provincial head of the local branch of the national forestry corporation, which is collaborating with the restoration of the marshland. The Rano Raraku volcano and its Moai are a UNESCO World Heritage Site
