It is clear to me that the onset caused massive disruption of human life in North America. The 1275 -1300 dating corresponds to the massive change in the South west and Cahokia.

I've been seeing articles popping up lately touting Ubehebe Crater in Death Valley as last erupting only 800 years ago, rather than thousands, "with profound effects upon the Southwest...".

First thing that came to mind was the Anasazi.

There was also an active volcano field around the same time at Flagstaff. There are several cones at Sunset Crater National Monument and the plain north towards the Grand Canyon has many.

I hope to go to Death valley in May and will have a look.
