Easter Island heads would possibly were positioned via consuming water resources.

The lost civilization of Easter Island could have selected the site of the enduring moai heads to sign the place recent water used to be to be had, a find out about has recommended.

Carl Lipo, an anthropologist who has spent nearly 20 years finding out the Rapa Nui – People and their disappearance from Easter Island, used to be taking a look at how the inhabitants used to be ready to live to tell the tale with such restricted get right of entry to to consuming water. Across the island, there’s little or no get right of entry to to freshwater—springs and streams are nearly totally absent and there’s little or no rainfall (roughly 48.eight inches consistent with year). So how did a civilization of an estimated 15,000-20,000 at its top set up to live to tell the tale?

To in finding out, Lipo and co-workers performed box research taking a look at how the islanders would possibly have used brackish groundwater discharge that surfaces alongside coastlines. Brackish water is saltier than commonplace water, however no longer as salty as seawater. Previous accounts from European explorers indicated the Rapa Nui – People drank brackish water, however the place they accessed it used to be no longer identified.

Lipo’s analysis, printed within the Hydrogeology Journal, reveals the islanders will have survived via consuming the brackish groundwater discharge that turns into ponded in trenches alongside the coast, or that floats at the coastal waters of the island. “Two field surveys indicate abundant locations of brackish but potable water along the coastline… Although coastal groundwater sources are of poor quality, they were apparently sufficient to support the population and allow them to build the magnificent statues for which Easter Island is famous,” the find out about concludes.

What is extra intriguing, alternatively, is the site of the water resources and the location of the Easter Island statues. The moai seem to have been positioned at spots the place consuming water used to be to be had.

The statutes—which is able to achieve as much as 30 ft in peak—are carved from compressed volcanic ash. In general, there are nearly 900 statues. They have been constructed one day between 1200 and 1600. After the Europeans arrived within the 1700s, they have been toppled over, which has been attributed to tribal battle and an earthquake. 

Why the Rapa Nui constructed those statues and what function they served isn’t totally understood. It is believed they have been symbols of spiritual and political energy, representing the traditional ancestors of Polynesians. Most of the statues are positioned at the coasts of Easter Island—Lipo suggests this will have been achieved for sensible functions.

“Now that we know more about the location of freshwater, however, the location of these monuments and other features makes tremendous sense: they are positioned where freshwater is immediately available,” he stated in a remark.

The team will now attempt to higher know how intently the site of the moai and the provision of consuming water are tied. This may sooner or later supply solutions about 1 of the sector’s maximum enduring archaeological mysteries. “This information ultimately sheds light on the conditions that drove and enabled these communities to work together to achieve their feats of engineering,” Lipo stated.

The Rapa Nui civilization collapsed after the arriving of European explorers. Foreign illness is believed to have performed an enormous position of their loss of life—along side the slave raiding expeditions within the 1860s.
