So what is at the bottom of this Wisconsin lake?

A new book, The Dragon in the Lake, seeks to answer the question:

In the cold murky depths of a Wisconsin lake lay mysterious rock structures wrapped in Native American folklore and local legend. These ancient underwater manmade structures may be the most significant and controversial North American archaeological discovery of the twentieth century.

In Archie Eschborn's fascinating new book The Dragon in the Lake, you will follow a small band of amateur archaeologists led by Eschborn himself as they reveal new research opening up a new chapter in prehistoric North American history and ending decades of controversy on North America's most sacred and secret native American site.

In North American archaeological circles, one of the great enigmas is who mined the millions of tons 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”
