Solution to the mysterious traces of "rock caps" at Easter Island

Researchers at the University of Oregon have recently come up with solutions to the mysteries of the "stone hat " on Easter Island.

Accordingly, these "stone hats" symbolize the chief's bun . They won in the races for power, so they were honored by great statues.

Of the more than 1,000 statues (called Moai) on the island, only about 70 hats are found, indicating that " stone hats" are not for all but "rewards ", symbols of rights. force . Through research, each hat weighs several tons, made of volcanic slag with characteristic red color. Not only that, but on the top of the hat there is also a bulky cylinder (called Pukao) that looks like a Russian fur hat.

Sean Hixon of the University of Oregon said that historians and ethnologists said that hats were ornaments. However, at the largest statues, decorative caps on the hat can be as high as 2m, weighing up to 12 tons.

Nobody knows exactly what the blocks on the hats mean, but they are carved in a subtle and completely different way.

Many theories have been put forward. In it, some people said that the ancients had to gather a lot of stones, then use the trunk as a roller to transport to giant statues placed on high pedestals.

Hixon and his colleagues used simple physics to describe how the ancients took tens of tons of statues to the mountains. For example, the ancients used the pulley system or created a long way to the giant tower to build Pukao Moai and hats at the same time.

The elongated shape will have an advantage over a circular cross-section, so it will prevent the Pukao from rolling down the slope by accident. Experts discovered a few dents about 2cm thick on each Pukao . This is said to be the vestige of the rope and traction of the ancients when they have to drag them on a long road.

However, not all Pukao has that dent. Some researchers believe that it was the erosion of the weather that changed Pukao's surface and made it difficult for them to identify the scratch.Experts are still conducting research to find the final solution to the mysteries of Easter Island - one of the greatest mysteries of humankind.
