Almost
all moais were carved out of characteristic, compressed, easily worked volcanic
ash. The biggest one weights up to 165 tons & its height is almost 22
meters. Some upright moai have become covered up to their necks by shifting
soils. This huge production of
megalithic works on an Easter Island that is absolutely barren, with
just grass, right away captures our imagination.
Some
scientists suggest that Easter Island population,
the Rapanui came from Polynesia. However similarities to Indian stone statues
around Lake Titicaca in South America are striking.
