The mysterious volcanic hats atop the statues.
Researchers believe they’ve figured out how the remote Easter Islanders were able to place huge rock “hats” on their distinctive statues, but they still don’t know why.
The hats were carved from volcanic rock. "We know the hats were rolled along the road made from a cement of compressed red scoria dust," archaeologist Colin Richards tells the BBC. Each hat weighs several tons, but the reason for the hats remains unknown.
"These hats run all the way down the side of the volcano into the valley,” he says. "We can see they were carefully placed. The closer you get to the volcano, the greater the number.”
Easter Island lies 2,500 miles off the coast of Chile and is one of the world’s most remote places inhabited by people. "The Polynesians saw the landscape as a living thing, and after they carved the rock the spirits entered the statues," Richards adds.
The research team is from the University of Manchester and University College London, the first English archaeologists to work on Easter Island since 1914.
