An independent pollution-control agency has rejected environmentalists' claims that a planned landfill could desecrate possible burial grounds near the ruins of a once-thriving prehistoric city.
Environmentalists say the expanded landfill site would be within 2,100 feet (640 meters) of the Cahokia Mounds site, which was among the among the most complex, sophisticated societies of prehistoric North America. As many as 20,000 people lived during its peak of 1100 to 1200 A.D.
Not enough there to really judge what's going on.
