Copper crystals pre-historic pit on Mount Bohemia Keweenaw County Michigan This miniature copper came from a pre-historic pit up on Mount Bohemia, not far from the Mendota mine. The ancient people were "mining" a vein of copper that happened to be crystallized to make tools (arrowheads, fish hooks, etc.) This race of people has been dated to over 5,000 years ago by archeologists. The crystals are crude, but what a story they could tell. Found in 1997. 4.5 x 3.6 x 0.7cm TM 19-816 SOLD |
