Cahokia-America's Lost City (Beneath St. Louis) 

It’s for sure why they had the ability to grow like that in one area because they would have overused the soil if not for the floods bringing in fertile silt on a regular basis. I know Moundville sits on the warrior river but on the bank that is slightly above the floodplain with the opposite side of the river being on much lower land that see’s flooding and where they grew large fields of maze and I’m sure squash and beans in large areas also. Makes me wonder if they had the same technique for growing squash as my father taught me where you make a small mound about a little bigger than a foot across so you can make it around a foot high then plant a few seeds in the top after making a little dip in the top and then a few inches deep. It’s been a while so look up that seed depth if anyone reads this and thinks they’ed grow some squash doing it that way. We always planted cucumbers and zucchini the same way and of all the things I’ve ever planted those three were the easiest and had abundant yields to the point I’d let cucumbers get way to big and have to throw some in the compost pile before they quit producing.

Imagine if instead of building a massive levee system on the Mississippi River we had taken a fraction of that fill material and built large mounds and moved the river towns on top of them. I think these people came up with the cleverest adaptation to life in a floodplain they just built high ground to which they could retreat when the river came up. These folks were very smart, and they used the available technology and resource base to make life possible in this complex environment.

@@ben-jam-in6941 you make an excellent point about the sediment from floods keeping the soil from depleteing. Just keep in mind that we witness that phenomena today but we have a massive amount of people which depletes soil faster (need more crops to feed them!) That said, i digress, as i didnt consider living close to lands that flood by building up as to avoid the waters when they rize will allow one to work the flooded land quicker

There was no earlier civilization. Nice try though.

Don’t need your approval when we already hold proof. I live in and have been unearthing evidence for decades-your universities look foolish

@@Great-Documentaries You are completely wrong

The British say they didn’t build Hadrian’s wall, they inherited it from an earlier civilization, the Romans. The mounds were abandoned by 1350, 400+ years is a long enough break to say an earlier civilization created them. But many of the cultural practices defused into other Indian cultural practices like chunky, which originated in Cahokia was still played by the Mandan as recorded by George Caitlin.
