#3Interesting to consider why they might have wound up at Cooper's on the Salmon River

instead of going farther up the Columbia. Might not have been a viable option!

"On the western edge at the Haida Gwaii ... the lower thickness of the ice sheet meant that sea levels were as much as 170 metres lower than they are today.... migrants ... were able to travel southward during the deglaciation process due purely to the exposure of submerged land between the mainland and numerous continental islands...."

Or they did go further up the Columbia and we haven't discovered evidence of it. It's not easy for things to survive for fifteen thousand years.

#5National Geographic marks the coastal route (20k - 15k ago) on their maps for schools. So it seems it's an already accepted theory?

Nor would the timing of the last predicted flood of Glacial Lake Missoula help.

#9Very sparse on details. Artifacts in Texas also point to possibly 15500 years ago. A northern origin might put Idaho even earlier. (https://www.ncbi.nlm.nih.gov/pubmed/21436451)
That said, I'm always extra cautious with claims out of Idaho and Utah given the density of people with very high desire to find ancient civilization. Eg the ongoing search and occasional "Discovery" of Nephilim Giants.

This family of theories has been around for a while, 1491 by Charles Mann discusses them extensively, and that book is from 2005. Reliable evidence is sparse though, so this could be a major contribution.
