Three of the papers list Chatters as an author, but he does not sign on to the view that Kennewick Man came from somewhere far away.

“If he’s an eater of seals, he’s in the wrong position,” Chatters said. He said Kennewick Man is more than 100 miles from the nearest seal.

Base ignorance on the part of Chatters-Seals (and their cousins the Sea Lions) can & do travel long distances up freshwater rivers here in the Pacific Northwest-it's common behaviour.
