Knowing that it becomes hard to believe the Sa'ami (or proto Sa'ami) wouldn't have trekked the ice across the Atlantic to become what we know as the Clovis Culture. That makes sense that Solutrean/Clovis culture is derived from the Sa'ami.
They brought their birchbark and teepee culture to this continent.
So Hiawatha was a Sa'ami!
Hiawatha could literally have been a cross between a Japanese and a Sa'ami ~ those guys have been drifting around the Pacific Litoral for thousands of years and show up just everywhere.
The problem is they can't go back! The trip West is very difficult. The trip East is possible for a guy in a rowboat.
