Beginning as much as three thousand years ago, this long-ago society—Erickson believes it was probably founded by the ancestors of an Arawak-speaking people now called the Mojo and the Bauré—created one of the largest, strangest, and most ecologically rich artificial environments on the planet. These people built up the mounds for homes and farms, constructed the causeways and canals for transportation and communication, created the fish weirs to feed themselves, and burned the savannas to keep them clear of invading trees. A thousand years ago their society was at its height.
