>>12080023I live in michigans copper country where this all went down and even find copper tools once in a while....there is NO WAY IN HELL the miners stayed here over the winter....the areas the anchient mines are in get 400 inches of snow on a normal year... but holy shit did they do alot of mining in hard rock without explosives....there was non memory of the mining when europeans got here and the indian mine pits had trees growing in them that were hundreds or hears old. the tools have the same amount of patina on them as the glacial float copper we dig up here. easy 10k years old.....
