The people of the Vikings also were in America before Columbus. They even had a village in Canada but after years of bad luck weather decided to abandon it. There's been some archaeology on this site. Very interesting. Also, there were about a dozen Eureopean-based skeletons found in various places in the US (Oregon, Ohio valley, etc) dating far before the "natives" migrated across the Bering Strait. I've forgotten how early the cave-woman of LA dated. She had Asian heritage and was very very old. Diane
