The Monumental Earthworks of Poverty Point is beingnominated by the U.S.Department of State for inscription on the United Nations Educational, Scientific and Cultural Organization's (UNESCO) World Heritage List.
Poverty Point is an amazing site! It's amazing for the sheer scale of the earthworks, which are spread across more than 700 acres, but the most incredible thing about it is that it dates to between 1700 and 1100 B.C. If you're not familiar with the timeline of eastern North American prehistory, that span of years lies within the Late Archaic period. The cultures of that era depended upon hunting and gathering for their livelihoods and, in Ohio at least, they were not yet building mounds let alone gigantic earthworks on the scale of Poverty Point.
