Another mystery of Easter Island is revealed by scientists from the University of Manchester and University College London.
Their collective work is to answer the origin of the huge stone with red hats, which are placed on the heads of some gigantic statues of people scattered over the surface of the island.
Experts said that the hats are made of stone formed by an ancient volcano nearby. Each of them weigh several tons. It is assumed that cylindrical hats were made on the spot in the crater, and then were rolling up the valley for a long time whilst sprinkled with red volcanic ash.
But why are the hats placed on the heads of statues? , and what was their purpose? Scientists still can not tell.
