Or, it was dropped overboard by Indians say, 600 years ago while they were out fishing, geeze.
Sorry guys but if you actually saw all of the sizes and shapes of the stuff then you would realize that it is no ballast nor was it dropped off some canoe 600 years ago.
Although we are no experts on Chert, we are certainly bringing in the experts to qualify the find. These are DEFINITE OUTCROPS....some with fossilized coral growths on them (doubt they got that way in 600 years)
If you do some research there is more and more evidence of a Coastal migration of PRE-CLOVIS peoples that came across Canada and down what was then the East Coast of North America.
Plenty more to come.....just stay tuned :)
