I think they wrote the history books years ago, and everyone thought that was the truth, the way it is. Yes, there has been a lot of explorers on North and South America prior to 1492. I am sure there are many people who never heard of Cristabol Colon! There have been quite a few finds in Oklahoma and other interior states of early, very early, European explorers. A coin from Roman times was found in central US. A lot of this was also just tossed aside. As far as we know the Emanuel Point wreck is the oldest found shipwreck, but of course there are the old native indian dugout canoes found. I was on the Ichatucknee River years ago, and walking around a slough, and found what I think was a dugout canoe. It had cypress knees growing up through it, but it was a canoe shape, and felt like a dugout. I am sure that was much older than the Emanuel Point Wreck (Tristan De Luna). Keywestdiver, do you think your wreck is an old one? Real old? That would be nice. There are a ton of 1800s wrecks, of all kinds out there. Check it out good, and do recover something to date it.
