While doing some digging on my own account I came across
She has written on the subject. See:
"in press Ancient Copper Mining: Facts, Fallacies, and Public Education. Submitted to Proceedings of the 28th Annual Chacmool Conference, Public or Perish: Archaeology into the New Millennium, edited by L. Beckwith and N. Saxberg. University of Calgary, Calgary, Alberta, 1999."
Weren't we recently told in another context that Chacmool is but a student conference without peer review?
"in press The Complex Formerly Known as a Culture: The Taxonomic Puzzle of Old Copper, with Thomas C. Pleger. In Taming the Taxonomy: Toward a New Understanding of Great Lakes Prehistory, edited by Ronald Williamson. EastEnd Books and the Ontario Archaeological Society, Toronto, 1999."
Co-authered with Thomas C. Pleger. Now there is someone who really does seem to know something about old copper.
"1999 Wonderful Power: The Story of Ancient Copper Working in the Lake Superior Basin. Wayne State University Press, Detroit."
This looks a little better but seems to be aimed at an amatuer audiance. Amazon's details can be found at
There is no doubt that Susan R. Martin knows more about copper than most of the subscribers to this group but if, as Doug says, she is the leading authority on this field then it it implies a disappointing level of interest in the problem by the experts. Could it be that Doug has cited her because she has written the kind of debunking article which Doug likes to put on his site?
