Description: The Easter Island statues stand 13 feet high and each weigh about 14 tons. Their human-like heads-on-torsos are carved from rough hardened volcanic ash. The islanders call them "moai," and they have puzzled ethnographers, archaeologists, and visitors to the island since the first European explorers arrived here in 1722. In their isolation, why did the early Easter Islanders undertake this colossal statue-building effort? Unfortunately, there is no written record (and the oral history is scant) to help tell the story of this remote land, its people, and the significance of the nearly 900 giant moai that punctuate Easter Island's barren landscape. Some believe they were made by visitors from other planets.
