The canoe, which weighs some 1,000 pounds and is three-foot-wide, is thought to be the largest ever found intact in the USA.
It was constructed 800 to 1,000 years ago by digging out a cypress trump, most likely by the Caddo Indians, who settled in the area.
Mr Girard said a similar canoe was found locally in 1983.
Archeologist Jeffrey Girard from the Louisiana Archaeological Society and Robert Chip from the State Archaeological Division excavated the boat.Once you're pretty sure the person you're drinking coffee and/or sleeping with fancies you, it might be time to check out their living situation.As well as finding out whether or not they're married ('gift'), consider also investigating if they are a 'mambo' - the word for someone who lives at home with their mother.They may take several months to build what may feel like the romance of a lifetime and can even pretend to book travel to visit you, but they never actually arrive.Once they have gained your trust and your defences are down, they will ask you, either subtly or directly, for money, gifts, or your banking or credit card details.You can also get asked to go for a fika by someone who fancies you, or someone you've already slept with (but perhaps barely spoken to).
