Normally a lack of a sewage system and the accompanying vermin and disease are the reasons an old city became uninhabitable.
Naaa, a couple of generations of worthless “progressives” took over. That’ll muck up anything.
There are some very interesting YouTube videos on the Cahokians. Take a peek.
They had a shot as a long-term civilization, and blew it.
Would have been interesting for the conquistadors (sp) if they had kept growing.

Watch some of those shows on pre-historic cities and cultures. Almost all of those shows attribute any decline to “climate change”.
There’s a wonderful book “Hotel of the Mysteries” which is a parody of archaeology. Far in the future, archaeologists unearth a present day motel. They construct all sorts of stories about how it was a place to bury the dead, the abandoned cars were the remnants of hearses, the toilet was a way to contact the spirits of the underworld, etc. It’s hilarious and will cause you to think every time you see a show based upon archaeology.
