Since moving up here to Montana, I've read quite a bit on the effects of the Altithermal period and how it caused the extinction of two of the three types of buffalo, ended the Paleo style points and was the start of the notched points, and changed hunting methods of the northern plains people. Even with the library of Tx based artifact and prehistory books that I've amassed over the years of living in So.Tx, few mention how it affected/changed Tx., flora, fauna, or people living during that time period, (8,500 - 5,000 BP). The Alithermal period was global.
Just curious if anyone has found any info on that period's affect on Texas.
The evidence shows here in among other things, arch. digs in buffalo jumps.

Alti WHO ?

Never heard of it...
So I did some Google searching.....
WOW, what a global event..must have been a shock to people worldwide, Mongolian deserts turned to lush forests !

As to Texas, , , , One report indicates that the effect had little or NO effect on the low and middle latitudes..perhaps Tx escaped the full force of the condition, at least not enough to make a change in the cycle of artifacts time lines.
