Talk:Copper mining in Michigan

About "Fringe Writers"
"Fringe writers have suggested that as much as 1.5 billion pounds of copper was extracted during this period, but archaeologists consider such high figures as "ill-constructed estimates" and that the actual figure is unknown."

This is quite a biased way of writing, and not usual in Wikipedia. It gives the impression that "archaeologists" (presumably scientists?) are united in the view that "high figures" estimated for prehistoric copper mining at Lake Superior are an illusion countenanced only by "fringe writers" which group evidently contains no archaeologists (therefore no scientists?). 1.5 billion pounds of copper mined prehistorically is a high-end estimate. 500 million pounds of copper is more usual. Of course the actual amount is unknown. Nobody left any records known to us. "unknown" includes both of the above estimates as well as higher, in between and lower values, and therefore is not informative. Jwilsonjwilson (talk) 06:55, 29 December 2013 (UTC)

Copper divers in Lake Superior?
This would make a nice small addition -- the divers who recover native copper from the lake bottom, for the mineral collector specimen trade. Anyone? TIA, Pete Tillman (talk) 07:35, 29 December 2013 (UTC)
