Exciting find, something definite to indicate East-Asian and Alaskan Trade approximately 1000 years ago. Three East-Asian areas are mentioned. China, Korea and Yakutia, in present day Siberia. Some of the evidence includes obsidian artifacts with a chemical signature that that indicates an origin in Anadyr River Valley in Siberia.
Another item of evidence is the design similarity of armour fabricated from overlapping plates.
