I first came across this a year or more ago. Fascinating find. I saw tv documentary on this find and they showed the reason why people organized around this area was because of the kind of plant{ wheat? } that grew there.
Apparrently most wheats or grasses of that species fall off easily if touched i.e attempted to be harvested, but in this area, that wheat/grass kernal/fruit does not fall off easily when touched ergo made it more easy to harvest and manipulate.
The other more speculative ideas come from the picto-graphs on one of the monuments. Some who have studied them show that the people of that time witnessed a metorite impact that occurred in Norht America in the approixmate time.
Ive had read and seen various info regarding this metor impact at a time the ice age may have been in decline{?} over North America and specifically north of the great lakes in US. Apparrently there is not an impact crater because the meteor hit only thick ice.
So ice melted but Earth was not impacted enough to be record or show evidence of the impact.
The third thing that is interesting to the scientists is that it appears that whoever built these monuments and temple intentionally buried it with rocks, Because the used rocks --instead of Earth/Soil-- water ran off and did not do signifcantly damage to the site.
Another aside I read somewhere —an foget many of the details-- was that Fullerenes were created from this impact and they have found these Fullerenes in caves in South or North Carolina ergo more evidence that there were some severe pressures created on Earth at around this time.
In the same program or another, they gave a scenario that we may have had Indians from Europe who lived on East coast, and when the impact happened, storms not only caused the exstinction of woolly bison and saber tooth tiger, but that those East coast Indians may have migrated west in search of more fertile and/or warmer environment.
They then met the Clovis people of Texas or New Mexico. So we have two kinds of spear heads there what being created East Coast Folsom and Western Clovis and the two cultures encountered each other.
One from European route/pahways and the other from Asian route/pathways.
