Lake Superior, the largest of the north American Great Lakes, it is also the largest freshwater lake in the world by surface area.
Believe to have first been inhabited 10,000 years ago after the retreat of the last Ice Age
However, there exists copper mines upon many of the lakes islands, which many researchers have concluded to be prehistoric.
A sophisticated array of tunnels litter the islands, or more specifically all of north America.
Scarred by ancient mine pits as deep as 150 feet. Carbon-14 testing of wood remains found in sockets of copper artefacts indicated that they are at least 5700 years old.
Although many have suggested that artefacts and evidence at some sites, has suggested a date far older than what has been put forward.
For example, some investigators believe that the mines were not even built by humans, but are the remains of a sophisticated mining operation that was once undertaken by alien visitors many thousands of years ago.
Similar in scale to the ancient Carolina Mica mines, Mica being a material which we use in electrical components.
The ancient copper mines on Superiors isle royale for example, although predictable disputed, produced over 750,000 tons of copper for a sophisticated group of ancient, mystery miners.
Findings published in 1961 within, “Prehistoric Copper Mining in the Lake Superior Region, by Roy Drier and Joseph Du Temple.
It must be noted that all of these pregistoric mines show evidence of being abruptly abandoned, whether this is evidence of the death of an unknown king or queen, or evidence for catastrophe is unknown, all along lake shore are vestiges of this once highly successful, ancient operation.
The most astonishing of remnants catalogued publicly, has to be the enormous lump of pure copper, found in 1771, near the bank of the Ontonagon river. In 1945 it was floated down river on a raft by a james k paul, and was eventually appropriated by an agent of the united states government, it was then shipped to Detroit and on to Washington, where it eventually slipped into the bowels of the Smithsonian.
Known as the Ontonagon Boulder it weighs 3,708 pounds, it was apparently well known to Native Americans. According to the Keweenaw Bay Indian Community, the boulder was used by tribe members to make offerings to its “manitou” or spirit, to seek improvement in their health and well-being.
Just how old is the Ontonagon Boulder? Or indeed the mine in which it came from?
Although many would like you to believe the mines are less than 5000 years of age, we think many factors surrounding them, suggest they are far older than that.
