“This is an excellent book that deals with the history of the Anasazi, the Hohokem and the Mogollon peoples that had large populations and cities in the Colorado Plateau, the Phoenix basin and the highlands in between”
What you site is a study that suggests “widespread” inter-tribal trade across the southwest and north of the Rio Grande.
You suggested, in your original comment, that the widespread trade was with groups south of the Rio Grande.
I continue to contend, as I said, the tribal groups in the southwest and north of the Rio Grande, had awareness of and contact with groups far south of the Rio Grande, but THAT contact did not constitute “widespread trade” from north to south of the Rio Grande. The vastly more correct “widespread” thesis is ACROSS the southwest, north of the Rio Grande, as study you cited suggests.
No, you are grossly misinformed. The Rio Grande has nothing to do with the trade routes across Arizona and New Mexico into the south.
You are behind in your studies. The incidence of trade with the south is well known and documented.
I gave you the reference. It can be delivered to you in just a few days........ read it
