Hi All,

Couple of historical notes, somewhat off topic:

There was indigenous ironworking going on in the Arctic--the Greenland Arctic. Bits of the Cape York Meteorite (which landed on the Cape York Peninsula, NW Greenland roughly 10,000 years ago) were being cut off and cold forged into blades at least 1000 years ago (ref: McGhee, Ancient People of the Arctic, 2001). The meteorite is currently at the American Museum of Natural History (AMNH link)

I'm still looking for images of these blades, but I suspect that they would have been small tools, rather than big daggers. Cold forging means pounding a flake into shape and scraping it sharp, and that would take a lot of effort to make any sort of useful blade.

I'd also point out that the "Old Copper Complex" in the western Great Lakes area dates back to 6,000 years ago, although copper working was confined to jewelry by 3,000 years ago. Apparently, when the copper mines in Michigan were found by Europeans, they were human-worked pits with the tools still in them.

Basically, copper working isn't new to North America. The big issue to make it work is heat and technology. Copper melts at 1085 deg. C, about 200 deg C hotter than a campfire. Because of this, you need some precursor technology, such as a pottery kiln, to provide expertise and technology in getting the proper temperatures. Iron can be similarly worked in a bloomery at 950 deg C up (1070 deg. C is apparently optimal). This is lower than the temperature required to melt iron (1538 deg C), but importantly, it requires bellows and charcoal to work.

So if we're looking for a culture that has independently developed iron or copper smelting, I think it's a safe guess that they'd also have things like ceramic pots, probably bellows (or at least blow tubes), and some other technological infrastructure lying around. While I have great admiration for the skills of the tribes of the Pacific Northwest and Pacific Arctic, they weren't potters. Rather, they were carvers and weavers. Prior to Contact, I think they worked native copper lumps whenever they could find them, but they didn't start working big sheets of copper until those were available through trade with the Europeans (the copper was used to coat the hull to make it worm-proof, and ships carried extra for repairs).

So far as figuring out how old the daggers are, I think this sets an upper limit. They probably could not have been produced prior to European contact. The tribes didn't have the precursor technology necessary to get enough copper (let alone iron) to make them. However, other groups (notably the Hawaiians) learned how to work with iron quite quickly after they met their first blacksmiths, and I'd bet that's the case for the PNW as well. They weren't stupid people, after all, just limited to the technology that their local environment could sustain.

My 0.00002 cents,
