I vaguely remember reading about "ancient Egyptian artifacts" found in Michigan as proof that somehow they were able to cross the ocean. Can't remember exactly where though, I cruise a lot of wacko sites. Well, in case you actually come across someone who talks about them, as you'd expect they're all fakes, and bad ones at that:

Last June [2002], [artifact invenstigator Richard] Stamps visited the Slate Valley Museum on the New York-Vermont border and asked workers there to examine several of the relics. The workers could identify the specific quarry each piece came from and what it originally was made to be: a window sill, a shingle or other construction pieces. But one trapezoidal tablet still puzzled Stamps. In the next room, he looked at a display of items made from slate, including a laundry tub. On closer examination, he noticed the end pieces of the tub were trapezoids, exactly matching the tablet.
