500 years of drought indicates no fake science but a natural solar cycle.

Exactly my point!

Before the 500 years of drought there was something else.

Climate changes and the power of the sun dictates how and when.

500 years takes the drought to 1850. In reading up on great plains\midwest droughts, the whole 19th century was considered dry with periods of drought.
The prior century as a whole was considered wet.

Which makes me wonder how Cahokia was in a 500 year drought ?
Here’s an older article with some different spin.
