Laser-scanning surveys reveal that the ancient Aquiry civilisation was bigger than previously thought, building tens of thousands of large geometric earthworks in what was once thought to be pristine wilderness

The Aquiry civilization comprised between 1.25 million and 3 million people around AD 100–300.

Many of these structures date to around C.E. 100–300, during the time of the Aquiry civilization, and may have been used for ceremonial purposes
