The two unusual artefacts (previous post) on right side in the net, now have lots of company in the Lake Superior area, and they have a name and a reason for being here.
Copper flaking baton heads.
Thanks to a talk with Tony Romano at the Archaeology Workshop at LU on Saturday, March 17, 2012.
I'll get a better photo and post it later...along with what they did.
A lot of new research and discovery has gone on in the last thirty years. Copper Culture artefacts are now ranging back from 3 to 5ooo years ago. Later in the "Fenwick papers" of 1938 etc you will read where they were trying to tie the copper artefacts to Viking influence.
