Statement of Significance (as of designation - June 13, 1962):
Poverty Point is the largest and most complex Late Archaic (4000 to 2500 B.P.) earthwork occupation and ceremonial site yet found in North America. The site is dominated by the immense Poverty Point Mound A, which is 640' by 710' in base dimension, and rises to a height of nearly 70'. First noted in the scientific literature in 1872, it was not until the early 1950's, with aerial photography, that the six concentric earthen ridges, became apparent. These earthworks, plus five other earthen mounds (Mounds B-E and Motley Mound) comprise the Landmark. It has been identified as a possible World Heritage Site.
