New Paper about Göbekli Tepewith and the Younger Dryas Impact

New Paper about Göbekli Tepewith and the Younger Dryas Impact

A recent paper in Mediterranean Archaeology and Archaeometry discusses the Göbekli Tepewith
Site in Turkey in the context of the Younger Dryas Impact hypothesis. It is:

Sweatman MB, Tsikritsis D. Decoding Göbekli Tepewith
Archaeoastronomy: What Does the Fox Say?. 
Mediterranean Archaeology and Archaeometry. 2017;17(1):233-50.

Some comments on the paper can be found in

The paper seemed like an exercise in speculation and personal opinion lacking a firm basis in evidence
and unconstrained by what other researchers have published and documented.They certainly failed to consider what modern geologists have written in published peer-reviewed articles in plain English in reference to Spokane / Missoula Flood as seen in the statement:

"Analysis of the geology of the Scablands and similar features across North America indicating
sudden melting of the Laurentide ice sheet and immense flooding across large areas of North America."

The fact of the matter is that the "analysis of the geology of the Scablands and similar features
across North America" had shown that the Laurentide ice sheet did **not** suddenly melt at the time of their alleged impact. It has been clearly demonstrated that there has been multiple Missoula Floods over the past 1.5 to 2 million years and that the significant flooding events predate the hypothesized Younger Dryas Impact event. At least, in respect to the Missoula Floods, their ideas are unconstrained by the known evidence.
