Last year, researchers associated with the Younger Dryas Impact Hypothesis claimed that an exploding comet destroyed the Hopewell culture of ancient Ohio. At the time, I pointed out many of the reasons their claim did not pass the sniff test, notably because Hopewell culture persisted more than two centuries after the supposed impact. Now, a new paper in Nature confirms that the original claim is almost absurdly flawed: Tankersley et al. claim a cosmic airburst over modern-day Cincinnati, Ohio in the 3rd or fourth century CE catalyzed the decline of Hopewell culture. This claim is extraordinary in the face of hundreds of archaeological investigations in the Middle Ohio River Valley (MORV) that have heretofore provided no evidence of a widespread cataclysm or “social decline” in need of explanation. Tankersley et al. misrepresent primary sources, conflate discrete archaeological contexts, improperly use chronological analyses, insufficiently describe methods, and inaccurately characterize the source of supposed extraterrestrial materials to support an incorrect conclusion. While charcoal and burned soils are found on virtually all excavated Middle Woodland archaeological sites in the region, these have prosaic explanations. Many of the burned “habitation surfaces” mentioned are actually prepared surfaces for ceremonial fires, not the result of a synchronous regional catastrophe. Radiocarbon dated samples from one context are mistakenly attributed to distinct and unrelated contexts. The chronological analysis does not support the notion of a single event spanning 15,000 km2. The composition of their supposed extraterrestrial materials is inconsistent with an origin in comet or asteroid events. In sum, there is no evidence to support the conclusion that a comet exploded over modern-day Cincinnati in the third or fourth century CE. The whole paper is a great read and a decisive rebuke to the expansive but fantastical types of claims Younger Dryas Impact Hypothesis researchers have proposed.

There is no definitive evidence that the Shawnee occupied that area or even existed 1500 years ago. Maybe that is why.

The fascination lies in pointing out your lying fake Injun lies. You never once took a photograph? Not much of a researcher, certainly not $30,000 worth though I notice you cut the amount from $40,000 on the Wikipedia Walam Okum or whatever discussion/talk page #2. Cutting prices is the first move of the past-her-prime whore. So you are minimally self-aware on a good day. But still a lying Sacajawea.

Also, as far as oral traditions go, hearsay passed down through hundreds of mouths through millennium of peoples who have gone through extreme social, religious and political upheavals for the last five hundred years will never be considered scientific or historical fact.

Before you said he was "literally" a Nazi. Which is it, or will it cost $30,000 for you to explain what you said? By which I mean to explain that you lied, again, as you do habitually.

My understanding is that the Tankersley et al. paper was officially retracted by the journal a few days ago based on the critique. One of the authors agreed with the retraction. The others apparently declined to discuss the matter with the editorial staff.
