Poverty Point contains a collection of earthworks built during a 600-year period. The mounds are concentric half-circles, 4 to 6 feet high with an outside diameter of three-quarters of a mile apart.
With no human remains or heaps of shells, archaeologists assume that these mounds were simply symbols of power and wealth.
Dating to the Late Archaic period, the people lived in small groups at Poverty Point. There were most likely hundreds of residents.
