Bob,
Interesting stuff! There are a couple of books that you may be interested in written by Barry Fell, Professor Emeritus of Biology at Harvard University. They are "Bronze Age America" and "America B.C.".
They address the possibility that North America had been explored and colonized by peoples other than American Indians. In fact, certain tribes may be directly related to these outsiders, some more than others.
For instance, I went to school with a guy that was 100% Iroquois Indian. To look at him he seemed as white Anglo Saxon as anyone else.
Fell links these peoplesâ€â€such as the Phoeniciansâ€â€with artifacts as well as writing inscriptions found throughout the country. He claims that this expansion of seafaring peoples was spurred-on by the quest for resources during the Bronze and Iron Ages.
There are also amazing similarities some of these inscriptions have with Egyptian Hieroglyphics.
I bought these books in the late '70s and early '80s when they were first released. They have long since been out-of-print but are available through Amazon if you're willing and able to spring the cash for them.
Here is a link to the Barry Fell books....

The book is a study of the prehistory and contact period history of native American tribes in the Merrimack Valley area of Massachusetts. The book was signed and given to me by the author.
John (Jay) was a friend and we would get-together for free form jazz jam sessions where he'd play flute and recite beat poetry. It was a blast! I still have all the recordings.
Here is a link to more information on it....
