Blair provides a thorough review of data he claims stands in opposition to our narrative concerning the origins of IIa40/Early Blue glass trade beads and their presence in arctic Alaska prior to Columbus’ initial voyage. He employs three lines of evidence: historical and archaeological data, Instrumental Neutron Activation Analysis, and radiocarbon dating. Our reply addresses his application of these data sets, clarifying his use of our data to arrive at his conclusions. While we continue to disagree with Blair, we do wish to acknowledge his time spent on debating the issue thereby furthering all of our understanding on this topic.

回复布莱尔

布莱尔对数据进行了全面审查，他声称这些数据与我们关于 IIa40/早期蓝玻璃贸易珠的起源及其在哥伦布首次航行之前在北极阿拉斯加的存在相反。他采用了三行证据：历史和考古数据、仪器中子活化分析和放射性碳测年。我们的答复涉及他对这些数据集的应用，阐明了他使用我们的数据得出结论的情况。虽然我们继续不同意布莱尔的观点，但我们确实希望感谢他在辩论这个问题上花费的时间，从而加深了我们对这个话题的所有理解。
