"international expert" ? I guess that's important since we AI's traveled the globe and established prehistoric American Indian colonies.
The modern plague of American Indians - archaeologists & anthropologists.
Keep in mind that the Cahokia city was contemporay with the large cities in Arizona, the Chaco culture and the Phoenix basin.
The peoples of the east, knew and traded with the west. The Southwest cities traded with the cities to the south. Thus, there was wide spread commerce that crosses the artificial present border with Mexico.
The key fact un mentioned is the source of the copper. Did it come from Tennessee or from Arizona?
Aside, I use the same technique of forging and annealing in my studio today. I have a little rolling mill that eases the hammering task and a gas torch for annealing and don’t use stones.
Also, before bending, a line, even a curved line can be scored with perhaps a flint to assure the break along a desired line
What?! Modern plague of Native Americans? I beg to differ, and take offense to that... So would many, many modern tribal councils. Archaeologists are the last hope that many tribes have to recording their ancestral heritage before it is destroyed by all of us. WE get one shot at trying to find what is there, before the land gets blown up. And, most sites found are only 25% excavated, as is the Federal guidelines. NO sites get 100% excavated, which is sad in so many instances...Wanna point fingers at who destroys what? Scream about Walmart...they bulldoze whatever is there...prehistoric graves, paleo sites, mound complexes, paleo point manufacturing sites, historic cemetaries, etc...pay their environmental fine for not completing the mandatory survey required by the Federal government, and build a store that makes up for the loss in one week. Wanna put a stop to destruction of our history? Start by not shopping at Wally World anymore...
Anyone who shops there both indirectly supports modern terrorism, and the destruction of American Indian heritage...Now who’s at blame?
