“Similarly, others think that the mined copper has gone “missing,” and that this perceived absence of artifacts in North America was further evidence for trans-Atlantic trade. I learned that this misunderstanding arose because most people are totally unaware that thousands of copper artifacts made by Native Americans have been found around Lake Superior and are still regularly discovered to this day. The reality is that these so-called missing copper artifacts were simply lost over vast stretches of forests, lakes, rivers, and prairies. One can only guess how many missing artifacts are actually out there. If the size and extent of the prehistoric copper mines around Lake Superior are any indication, thousands of artifacts are still likely to be found.” ArchaeologyArtifactsCopperNative American History Book:Great Water: The Lost Mines of Lake Superior Source: Great Water: The Lost Mines of Lake Superior
