Book excerpt: Archaeologists have been investigating the ruins of Poverty Point for decades, piecing together a fascinating picture of a 3,500-year-old hunter-gatherer way of life. But Poverty Point is more than an archaeological treasure-trove. It's also an eerie locus for southeastern native lore. Cold breezes on warm nights stir up spirit foxes and singing locusts. Otherworldly messages find their conduit in the drumming of trees and hooting of owls. Archaeologist and author Jon Gibson unearths the strange narratives that are as much a part of Poverty Point as the artifacts and earthworks themselves.
