EPPS, La. (AP) — Officials say the process to have Poverty Point named as a World Heritage site remains full-steam ahead.

Diana Greenlee, station archaeologist at Poverty Point State Historic Site in West Carroll Parish, tells The News-Star everything is running smoothly.

Greenlee says officials have submitted the draft nomination, through the National Park Service Office of International Affairs, to the UNESCO World Heritage Centre in Paris for a technical review.

The U.N. Educational, Scientific and Cultural Organization's World Heritage List includes fewer than 1,000 sites, and among them are the Grand Canyon, the Great Barrier Reef in Australia, the Great Wall of China and the Statue of Liberty.

Poverty Point is a vast complex of earthen mounds and ridges built by inhabitants more than 3,500 years ago.
