Interesting scenery, arrowheads not so much
A basalt [or actually black rhyolite] arrowhead missing its tip, from the Fairhaven side of New Bedford harbor. Video above.
Come to think of it, this proves the spot is worth exploring more carefully. Finding a place with arrowheads is harder, and more valuable, than finding individual arrowheads.
Update: I was excited to find this arrowhead. When I cleaned it up, it turned out to be nice flaking PLUS it was a new site PLUS it was a new material. So I went back a couple days later and examined that beach pretty carefully. Not a single thing was found - nothing. So why return after this? In fact this single, solitary, fragment of an arrowhead is all we are going to get from this place, short of some extensive digging. So that's it: we are never going to learn anything about who and when this arrowhead was made. A whole story, hinted at but lost. It is sad.
