Advance archaeological archaeology chronometric dating in in museum science

Over 25 years of experience in field collection and x-ray fluorescence analysis of geologic obsidian source materials and archaeological artifacts from the United States (Alaska, Arizona, Arkansas, California, Colorado, Idaho, Illinois, Iowa, Kansas, Louisiana, Minnesota, Montana, Nebraska, Nevada, New Mexico, North Dakota, Ohio, Oregon, South Dakota, Texas, Utah, Washington, Wisconsin and Wyoming), Canada, Iceland, Mesoamerica, Poland, South America, and Tibet.

At the same time of the research done by the Honolulu Museum, the University of Honolulu excavated several sites in O'ahu which would suggest dates of AD 600 to 1100.

Regardless by the close of the 1970s a model of Polynesian settlement chronology emerged suggesting multiple contacts with the island relying on the Pu‘u Ali‘i sand dune sample posited (although revised in 1969 as actually sometime between 10 AD) as supporting a possible earlier wave of settlement in 124 AD, with a long pause in between.

Over the next ten years the early radiocarbon dating of Hawaiian samples started to return dates suggesting sometime first humans arrived sometime between 300 AD to 800 AD casting doubt on Pu‘u Ali‘i sand dune sample.Accordingly, it was retested with the help of a second lab and to their dismay could not be replicated and was instead revised to roughly 1000 to 1350 AD.
