This is about rock piles and stone mound sites in New England. A balance is needed between keeping them secret and making them public. CONTACT: email@example.com
It certainly seems that split-wedged boulders outnumber wedgeless splits by a significant factor. I wish we had the statistics on it. I also wish we knew how many of these splits may have been created or helped along by stone tools.
In some places every split rock is wedged. Other places seem relatively free of them.
And sometimes you find a small split wedged/filled boulder and only a few feet away there is a car sized split boulder with nothing in it.You have to wonder why one and not the other.
My theory is that wedges close the door. So each door would have its own history of use.
