Povertypoint mound dates to 1600 BC...



but now there is evidence that the mound complex at Watson Brake goes back to 3400 BC...

Located above wetlands, the site would have provided access to vast aquatic resources during certain seasons. Bones of the freshwater drum, a species of fish that spawns from spring to early summer, and charred seeds of plants that ripen in the summer and fall were recovered at the site. The findings contradict the commonly held belief that major building projects took place only in complex societies with permanent villages supported by agriculture or trade. Mobile hunter-gatherers, it was thought, were unable to undertake such projects.

The inhabitants of Poverty Point, while not yet agriculturalists, had a complex social organization, took part in extensive trading networks, and possibly maintained year-round occupation.
