Things That Look Suspciously Man Made

In North American Archeological circles, one of the great enigmas is who mined the millions of pounds of pure raw copper from Michigan's upper peninsula and Isle Royale in the time period between 3000 BC and 1200 BC. Indigenous use of copper was limited to small-scale utilization and does not account for the prodigious amounts mined.

In European and Middle Eastern Archeological circles, one of the enigmas is where did all the copper come from to sustain the copper and Bronze Age cultures in the time period between 3000 BC and 1200 BC. Local sources were not sufficient and of the quality necessary to supply these large scale cultures.

Oral Native American history and lore deny any affiliation to the prehistoric mining operations; rather they cite 'ancient maritime foreigners' who mined the ' Red Rock '. All throughout North America there are archeological anomalies that point to the possibility of contact from Trans Pacific and Trans Atlantic visitors with pre-Columbian North American cultures. Additional, evidence suggest wide trade networks between the people of Mesoamerica and those magnificent indigenous cultures labeled as the �Mound Builders�.
